Clinical and Genetic characteristics of patients with Peripheral Retinal Fleck in Koreans.

To describe the clinical and genetic features of Korean patients with peripheral retinal flecks unrelated to aging. A retrospective analysis was conducted on the clinical characteristics of patients with symmetric peripheral retinal flecks. Age-related deposits such as reticular pseudodrusen were excluded, as well as secondary deposits related to intraocular inflammation, tumor, and drug toxicity. Multimodal imaging, electrophysiological examinations, and genetic testing were analyzed. A total of 10 patients (2 males and 8 females) with bilateral peripheral flecks were enrolled in this study. A mean age at diagnosis was 30.5±19.6 years (4-59 years). Within the 10 patients, 6 were genetically confirmed with monogenic retinal disorders. Biallelic pathogenic variants in RDH5 were found in 5 patients, and 1 patient was diagnosed with retinopathy related to Alport syndrome due to a pathogenic variant in COL4A5. Although not genetically confirmed, one case associated with nanophthalmos and another case showing chorioretinal mottling in a carrier of ocular albinism have been identified. In one patient, genetic testing also revealed unknown causes. The mean logMAR initial visual acuity was 0.12±0.18 and 0.07±0.18 in right and left eyes, respectively. Night blindness was reported by 4 patients (40%), with 3 showing decreased or delayed rod response in electroretinogram, particularly those with RDH5 mutations. Differences in the deposit layers and the patterns of flecks were observed on multimodal imaging. In the study population, we observed various causes and clinical differences in the retinal fleck patterns among Koreans, including RDH5-related fundus albipunctatus and Alport syndrome. Despite reports of night blindness symptoms in some cases, all patients demonstrated satisfactory corrected visual acuity.

Trajectories following Impella 5.5 support are associated with initial presentation acuity.

Impella 5.5 is a temporary left ventricular assist device utilized to support patients with cardiogenic shock and those undergoing high-risk cardiac interventions. From October 2019 to January 2023, 226 patients received Impella 5.5 support at Cleveland Clinic main campus. Patients were stratified by Society for Cardiovascular Angiography and Interventions (SCAI) shock stages. Immediate post-Impella 5.5 trajectories were compared across groups. Trajectories were defined as mortality on Impella 5.5, transition to advanced heart failure therapies (durable left ventricular assist device/heart transplantation), or survival to Impella 5.5 removal without advanced therapies. Overall, 148 (65%) patients with cardiogenic shock and 78 (35%) undergoing high-risk cardiac interventions received Impella 5.5 support. SCAI stage was A in 63 (28%), B in 10 (4.4%), C in 29 (13%), D in 104 (46%), and E in 20 (8.8%). Mortality on Impella 5.5 was highest in SCAI stage E (A: 3.2%, B: 10%, C: 14%, D: 27%, E: 35%; p < 0.01). Transition to advanced therapies (durable left ventricular assist device or heart transplantation) was highest in SCAI stages C-D (A: 1.6%, B: 0.0%, C: 45%, D: 36%, E: 20%; p < 0.01). Survival to Impella removal without advanced therapies was highest in SCAI stages A-B (A: 95%, B: 90%, C: 41%, D: 38%, E: 45%; p < 0.01). Stratification by presentation acuity in candidates for Impella 5.5 insertion may help identify which patients may and may not benefit from this escalation of tailored temporary mechanical circulatory support.

Persistent syphilitic ocular manifestations despite treatment: a case series

BackgroundPenicillin has remained the most effective treatment for syphilis for several decades. Syphilitic retinal manifestations may persist following treatment and cause visual problems. In this case series, we describe three syphilis patients with persistent posterior segment manifestations due to chronic inflammation, incomplete treatment, and reinfection.Case seriesRecommended initial treatment for all patients was 14 days of intravenous penicillin. Oral prednisone was added 48 h after initiation of penicillin therapy. Case 1: A 48-year-old female presented with gradual vision loss for two months. Fundus imaging revealed syphilitic outer retinopathy (SOR), papillitis, and acute syphilitic posterior placoid chorioretinopathy (ASPPC). After treatment, she had persistent cystoid macular edema (CME) and was treated with intravitreal triamcinolone injections and ketorolac drops. Case 2. A 24-year-old male presented with sudden vision loss for two days. On imaging, he had ASPPC, papillitis, and SOR. IV penicillin treatment was given for 10 days only. He had persistent SOR and was retreated with doxycycline and prednisone. Case 3: A 52-year-old male presented with eye pain and visual loss for one week. There was evidence of ASPPC and papillitis on imaging. One month after treatment, he had persistent papillitis and was restarted on oral prednisone. One year later, he was found to have recurrent ASPPC and was confirmed to be reinfected with syphilis, for which he was retreated.ConclusionWhen treating persistent syphilitic ocular manifestations, we recommend checking that the penicillin treatment was complete and the RPR titers are declining. If both hold true, then the affected eye should be treated with anti-inflammatory therapy. Other factors that contribute to poor visual prognosis include treatment delay, poor initial visual acuity, macular edema, and HIV coinfection.

Incidence, Mechanisms, and Clinical Characteristics of Traumatic Iritis: A Population-Based Analysis.

To describe the incidence, mechanisms, and clinical characteristics of patients diagnosed with traumatic iritis in a U.S. Midwestern county population. Retrospective population-based cohort of all residents of Olmsted County, Minnesota diagnosed with traumatic iritis from January 1, 2006, to December 31, 2015. The medical records of patients with traumatic iritis were identified using the Rochester Epidemiology Project database, which contains virtually all medical care in the county. Medical records were reviewed for demographics, presentation, and follow-up data. Incidence rates were calculated per 100,000 per year. There were 156 incident diagnoses of traumatic iritis during the 10-year study period, yielding an age- and sex-adjusted incidence rate of 10.7 per 100,000 per year. Traumatic iritis disproportionately occurred in male (p < 0.001) and Black (p < 0.001) patients. The mean age of diagnosis was 33 years (range: 4-96 years), mean number of traumatic iritis-specific follow-up visits was 2.1 (range: 0-26), and median duration of traumatic iritis-specific follow-up was 11 days (range: 1 day-1.6 years). There were 155 (99.4%) patients with unilateral disease. The most frequent mechanisms of traumatic iritis were sports-related (N = 29, 18.6%), assault-related (N = 23, 14.7%), scratch (N = 22, 14.1%), and work-related (N = 21, 13.5%) injuries. The mean initial and final best-corrected visual acuity (BCVA) of the affected eye was 20/40 and 20/30, respectively. Loss of follow-up was more frequently observed in Black patients (p < 0.001) and patients with smoking history (p = 0.004). Traumatic iritis was most frequently observed in younger males and Black patients. Common mechanisms included sports, assault, scratch, and work-related injuries.

Clinical factors and predictors for spontaneous separation of epiretinal membranes.

To investigate the clinical characteristics, imaging features, and predictive factors for spontaneous separation in patients with idiopathic or secondary ERM. The overall cohort was divided into two subgroups: idiopathic ERM (28 eyes, 56%) and secondary ERM (22 eyes, 44%). Electronic records and multimodal imaging were reviewed. Among the 50 eyes included in this study, the self-separation of ERM occurred over a mean duration of 28.1 ± 25.3months (median: 25.4months). Compared with the secondary ERM group, the idiopathic group had a shorter interval to separation (idiopathic vs. secondary, 23.4 vs. 34.1months, respectively; P = .01) and better vision at diagnosis (logMAR 0.094 vs. 0.224; P = .009) and after separation (logMAR 0.097 vs. 0.188; P = .01). Overall, in both subgroups, spontaneous ERM separation appeared to have been induced by posterior vitreous detachment (PVD) (P < .001). Multivariate analysis revealed that the self-separation interval (odds ratio [OR] 0.936) and IRF (OR 0.049) were significantly associated with complete ERM separation (all P < .05). Additionally, secondary ERM (OR 15.224) and lower initial best-corrected visual acuity (OR 267.589) were significantly associated with improvements in vision after self-separation (all P < .05). The self-separation of ERM appears to be induced by PVD development in most eyes. Owing to the possibility of complete spontaneous separation, surgical membrane peeling may be delayed by up to 28months in eyes without PVD, regardless of whether the cause is idiopathic or secondary. Patients with secondary ERM may experience favorable visual improvement after self-separation despite having poor vision at diagnosis and IRF on OCT. What is known • An epiretinal membrane (ERM), the most prevalent retinal disease in adults, is less understood regarding clinical factors and the accurate mechanism of spontaneous separation. What is new • The separation of ERM appears to be induced by PVD development in most eyes. • Favorable vision outcomes were associated with secondary ERMs and lower initial visual acuity. • Complete ERM separation was associated with a shorter self-resolution interval and the absence of intraretinal fluid (IRF) in OCT imaging.

Multimodal Imaging Characteristics and Correlation to Outcomes in Patients with CRAO Presenting to a Large Academic Center

PurposeTo characterize a large modern cohort of patients with central retinal artery occlusion (CRAO) by describing presenting features and outcomes relating to manually segmented optical coherence tomography (OCT) features, angiographic reperfusion, and visual recovery. DesignRetrospective clinical cohort study. MethodsPatients with CRAO (ICD-10: H34.1) initially presenting to a tertiary referral center between January 2017 and December 2021 were included. Demographics, eye exam findings, fundus photographs, OCT, and fluorescein angiography (FA) were analyzed. Main outcome measures included total and inner retinal thickness on macular OCT, reperfusion, visual outcomes, and development of neovascularization. Results145 eyes of 144 patients with mean age at of 69.4±13.6 years were included. The mean time to presentation was 1.6±4.2 days, with 19% examined within 4.5 hours and 26% within 6 hours of vision loss. 19% had cilioretinal artery (CLRA) sparing. Mean initial visual acuity (VA) was 1.68±1.10 LogMAR (CLRA sparing) compared to 2.53±0.58 LogMAR (non-CLRA sparing), P<0.001. 32% had elevated inflammatory makers. Out of 47 eyes with final fluorescein angiography, one-third showed some reperfusion. Final vision was 1.40±1.16 LogMAR (CLRA sparing) compared to 2.46±0.81 (non-CLRA sparing), P<0.001. A third of patients improved in VA in both groups, 27% of patients gained more than 2 lines of vision in the CLRA sparing group and 36% in the non-CLRA sparing group. 17% improved to better than 20/200 in CLRA-sparing and 4% in non-CLRA sparing. 11% developed neovascularization all in non-CLRA sparing. In a multiple linear regression, VA at presentation was associated with regaining vision of 2 lines or more (OR=2.603, P=0.007). OCT showed progressive thinning over time, reaching lowest measurements at 6 months, and stabilizing thereafter. ConclusionsIn this modern cohort of acute CRAO patients, presentation to a tertiary facility within 12 hours of symptoms was seen in almost half of the patients. Final visual acuity improved in almost a third of the patients, however, vision better than the legal blindness limit was rare (∼5%). Interestingly, a third of patients had some mild elevation of systemic inflammatory markers. Better visual acuity at presentation was associated with visual gain, while baseline OCT values had poor correlation with final outcome.

Risk factors and prognostic factors associated with retinal detachment and visual outcomes in acute retinal necrosis

ObjectiveTo investigate the risk factors and prognostic factors that affect the long-term clinical outcomes of acute retinal necrosis (ARN).MethodsA retrospective study of patients with ARN who underwent treatment and completed follow-up in our ophthalmology department from 2011 to 2021 was conducted. The incidence and risk factors of retinal detachment (RD) and prognostic factors affecting long-term clinical outcomes, such as late-onset RD and final vision loss (< 20/200), were analyzed.ResultsTotally 59 ARN patients (65 eyes) with an average follow-up of 48.9 months were enrolled. During the follow-up period, RD occurred in 34 eyes (52.3%). The risk factors for RD included quadrants of involved retinal necrosis (odds ratio [OR], 4.181; 95% confidence interval [CI], 1.950–10.834) and initial intraocular viral load (OR, 1.721; 95% CI, 1.071–3.083). Early intravitreal antiviral treatment (OR, 1.204; 95% CI, 1.040–1.480) was independently associated with a decreased risk of late-onset RD. The factors independently associated with an increased risk of final vision loss were worse initial visual acuity (OR, 3.895; 95% CI, 1.551–13.662) and late-onset RD (OR, 8.043; 95% CI, 1.380–67.216). In addition, we utilized the fluctuating magnitude of viral load to quantify the extent of its reduction in comparison to its original value following the initial intravitreal antiviral injection (IAI). This ratio was strongly related to initial intraocular IL-8 concentration (Spearman correlation coefficient=-0.741, P = 0.000) and moderately related to the initial degree of aqueous flare (Spearman correlation coefficient=-0.508, P = 0.010).ConclusionRD is a common and severe complication of ARN with multiple risk factors, such as initial retinitis involvement area and initial intraocular viral load. Active local antiviral therapy may reduce the risk of late-onset RD. The antiviral medication should be adjusted according to the inflammatory state. Therefore, timely detection of causative viruses and intensive systemic and local antiviral therapy is crucial for preserving visual function in ARN patients.

The Flip and Fix internal limiting flap technique versus the classic temporal flap for macular hole repair.

To describe a novel technique of macular hole (MH) repair and compare it to the perfluorocarbon liquid (PFCL)-assisted temporal internal limiting membrane (ILM) flap technique. Twenty-two eyes of 22 patients with MH were randomized on a 1:1 basis into two groups. Group A cases were treated using the Flip and Fix technique, in which the single-layer ILM flap was flipped, flattened over the macula using PFCL, and fixed in place using two drops of autologous nonheparinized blood over the superonasal and inferonasal edges of the flap (away from the MH center). Group B patients had the classic temporal ILM flap technique without using the PFCL or autologous blood. All patients were followed up for a period of 6 months after the surgery. No significant difference was observed in initial and final visual acuities between Groups A and B. Intraoperative flap displacement did not occur in Group A and occurred in two eyes in Group B (18.2%). One of them showed failed MH closure and required reoperation. These two cases had a final (W shape) MH closure and a worse final vision than the remaining cases, which had either a U shape or V shape final MH closure. The study results show that the Flip and Fix technique is as effective as the PFCL-assisted temporal ILM flap technique and is associated with less ILM flap displacement risk for the repair of macular holes.

Clinical-Laboratory Outcome of Cryptococcus sp. Multifocal Choroiditis in Acquired Immunodeficiency Syndrome Patients

ABSTRACT Purpose This study aims to describe the clinical and laboratory outcomes of patients with Acquired Immunodeficiency Syndrome (AIDS) presenting multifocal choroiditis secondary to Cryptococcus sp. infection. Methods We reviewed the clinical records of AIDS patients diagnosed with cryptococcal multifocal choroiditis at the Laboratory of Infectious Disease in Ophthalmology, Oswaldo Cruz Foundation, from January 2022 to March 2024. Patients meeting the criteria of typical fundus appearance associated with disseminated cryptococcosis laboratory diagnosis were included. Data collected included age, gender, symptoms, plasma HIV viral load, serum T-CD4+ cell count (cells/mm3), initial visual acuity (VA), laboratory methods for cryptococcosis diagnosis, treatment, and final VA. All patients underwent multimodal evaluation including spectral domain optical coherence tomography, fluorescein angiography (FA), and indocyanine green angiography (ICG). Results Six patients were evaluated, comprising five males (83%) and one female (17%), with a mean age of 36.5 years (standard deviation, SD: 10,46). Five patients (83%) presented with meningeal syndrome. Mean HIV plasma viral load was 262.959 copies/mm3 (SD: 209.469), and the mean serum T-CD4 count was 13.33 cells/mL (SD: 14,63). All patients tested positive for serum cryptococcal antigen (CRAG). Four patients (67%) had positive cerebrospinal fluid (CSF) culture and CRAG. Treatment included intravenous Amphotericin B and oral Fluconazole. Among twelve eyes (100%), four (33%) achieved visual recovery, while eight (67%) maintained initial VA. Lesions were more numerous and distinct on ICG compared to fundus examination and FA. Conclusion This study underscores the importance of clinical, laboratory, and multimodal evaluations in AIDS patients presenting with cryptococcal multifocal choroiditis.

Etiologies and Outcomes of Granulomatosis With Polyangiitis-Associated Optic Neuropathy: A Case Series and Review of the Literature.

Granulomatosis with polyangiitis (GPA), formerly known as Wegener granulomatosis, is a rare autoimmune disease characterized by inflammation of small- to medium-sized blood vessels (vasculitis). We described the 3 causes of GPA-associated optic neuropathy (compressive, inflammatory, or ischemic) and analyzed initial and final visual acuities (VAs) in each group, which could potentially help prognosticate visual outcomes depending on the etiology of optic neuropathy. This was a retrospective chart review of patients who were diagnosed with GPA-associated optic neuropathy and were seen in the Department of Ophthalmology at Mayo Clinic in Rochester, Minnesota. Only patients who met the 2022 American College of Rheumatology/European Alliance of Associations for Rheumatology GPA classification criteria were included. A total of 12 patients with GPA-associated optic neuropathy were identified. The etiology of the optic neuropathy was compressive in 6 patients, inflammatory in 4 patients, and ischemic in 3 patients. One patient had compressive optic neuropathy initially, then presented with GPA-related optic neuritis years later. Four patients in the compressive optic neuropathy group had orbital masses requiring orbitotomy for debulking, and the remaining 2 patients had compression from pachymeningitis. Average logarithm of the minimum angle of resolution (logMAR) VA at optic neuropathy onset was 1.50, 1.50, and 0.67 (Snellen equivalent 20/600, 20/600, and 20/100, respectively). At the last follow-up, average logMAR VA was 0.91, 1.73, and 1.10 (Snellen equivalent 20/160, 20/1,000, and 20/250, respectively) for each group. Visual outcomes were variable, with compressive and inflammatory optic neuropathies showing improvement in 4 eyes and worsening in 3 eyes in total. Patients with ischemic optic neuropathy from GPA were either stable or worsened over the course of the disease.

THE PROGNOSTIC SIGNIFICANCE OF ACUTE HENLE FIBER LAYER HYPERREFLECTIVITY IN PLACOID DISEASES.

To investigate the pathophysiology and prognostic significance of acute Henle fiber layer (HFL) hyperreflectivity in placoid diseases by examining its relationship with impaired choroidal flow and persistent photoreceptor disruption. Retrospective-prospective observational study on patients with placoid diseases. Indocyanine green angiography and optical coherence tomography were performed during the acute phase and follow-up. Impaired choroidal flow, HFL hyperreflectivity, and persistent ellipsoid zone disruption, their colocalization index, and their associations with initial and final visual acuity were explored. Sixteen eyes from eight patients (mean age, 25.3 ± 6.44 years) were included (median follow-up, 13.5 months). Quantitative analysis revealed significant correlations between areas of impaired choroidal flow, HFL hyperreflectivity, and persistent ellipsoid zone disruption (correlation coefficients of 0.69, 0.63, and 0.46, respectively). Impaired choroidal flow area exceeded HFL hyperreflectivity (P = 0.002) and ellipsoid zone disruption (P = 0.003). A noteworthy 94% nonrandom overlap between HFL hyperreflectivity and ellipsoid zone disruption was observed. Worse initial visual acuity correlated with foveal involvement (P = 0.0002), thicker choroid (P = 0.001), larger impaired choroidal flow areas (P = 0.02), and thinner outer retina post lesion inactivation (P = 0.04). Henle fiber layer hyperreflectivity predicted photoreceptor recovery potential in placoid diseases. If HFL hyperreflectivity corresponds to acute HFL damage, it may suggest more severe involvement of the entire photoreceptor length.

POSTINTRAVITREAL INJECTION AND POSTCATARACT EXTRACTION ENDOPHTHALMITIS VISUAL OUTCOMES BY ORGANISM: A SYSTEMATIC REVIEW AND META-ANALYSIS.

To compare visual outcomes of endophthalmitis following intravitreal injections (IVIs) and cataract extraction by causative organism. Searches in Cochrane Central Register of Controlled Trials, MEDLINE, and Embase identified articles reporting visual outcomes by causative organisms in post-IVI and cataract extraction endophthalmitis cases from January 2010 to February 2022. A random-effects meta-analysis compared visual improvement among endophthalmitis cases caused by causative organisms. Eighty-five out of 3,317 retrieved studies were included. The highest degree of visual acuity improvement in both post-IVI and postcataract extraction endophthalmitis was seen in cases caused by coagulase-negative staphylococci, followed by gram-negative organisms and other gram-positive organisms such as streptococci and enterococci. Culture-negative cases showed more visual acuity improvement than culture-positive cases in post-IVI endophthalmitis. These results remained consistent when accounting for endophthalmitis treatment, IVI type, condition requiring IVI treatment, follow-up period, and initial preprocedural visual acuity. Coagulase-negative staphylococci and gram-negative organisms show the most visual acuity improvement in both post-IVI and postcataract extraction endophthalmitis. Other gram-positive organisms such as streptococci and enterococci are associated with less visual improvement. This updated systematic review and meta-analysis revealed that the results of the Endophthalmitis Vitrectomy Study are consistent decades later despite advancements in surgical practices and the evolution of microorganisms over time.

Validation of Emergency Nurse Practitioner Competencies: Patient Complexity and Clinical Decision Making

IntroductionOver the past 15 years, the emergency nurse practitioner has been recognized as a nursing specialty role with dedicated scope and standards of practice. However, a paucity of objective data exists to validate the actual practice of emergency nurse practitioners in the emergency care setting. The purpose of this pilot study was to describe the initial acuity of patients assigned to emergency nurse practitioners, actions, decisional complexity, and disposition decisions of advanced practice nurses as they function in emergency departments in a single system. MethodsThis descriptive exploratory study used retrospective chart data to gain understanding. ResultsThe most common Emergency Severity Index level seen by emergency nurse practitioners was Emergency Severity Index 3. Of 8513 encounters with Emergency Severity Index level data, 21% were triaged at Emergency Severity Index 2, 56% at Emergency Severity Index 3, 21% at Emergency Severity Index 4, and only 2% at Emergency Severity Index 5. Half of encounters resulted in a Current Procedural Terminology code of 99825 or higher and 94% were coded at 99824 or higher. There were a high percentage of admissions including intensive care unit admissions. DiscussionAlthough descriptive, this study is highly illustrative of the broad scope of complex skills and clinical decision making required to perform as an advanced practice nurse in the emergency department. Further examination of education and training is warranted.

Evaluation of Prognostic Factors in Adult Chemical Corneal Injury.

The aim of this study was to evaluate prognostic factors that may be useful in predicting final visual acuity in patients admitted to the clinic with chemical corneal injuries. Data on age, sex, time to admission, irrigation solutions (balanced salt solution or phosphate buffered saline) and type of substance causing chemical injury were recorded. On admission, all patients were evaluated according to Roper Hall and Dua classifications. At the twelfth month after treatment, all measurements were repeated. A total of 131 patients with chemical corneal injuries [group 1 (acid, n = 73) and group 2 (alkaline, n = 58)] were included. The initial best corrected visual acuity (BCVA) level was "20/40 and above" in 32 patients (43.8%) in group 1 and 14 patients (24.1%) in group 2. According to Roper Hall classification, the mean grade was 1.92 ± 0.9 in group 1 and 2.27 ± 1.1 in group 2. According to Dua classification, the mean grade of the patients in group 1 was 2.16 ± 0.9 and 2.58 ± 1.2 in group 2. Posttreatment BCVA level improved to "1/200 to 19/200" in 8 (66.7%) of the patients with an initial BCVA level of "perception of light or hand movements." In univariate analysis, initial visual acuity and posttreatment visual acuity were statistically significant (P < 0.001). It was also statistically significant in multivariate analysis adjusted for sex and age (P < 0.001). In conclusion, the treatment of chemical corneal injuries is a long and exhausting process. The use of initial visual acuity and Dua classification in prognosis prediction may provide high success.

Visual deterioration outcomes following optic pathway glioma treatment: a 12-year single institution retrospective study.

The surgical treatment of optic pathway gliomas (OPG) remains controversial, with visual outcomes often unpredictable. The present study explored surgical and clinical factors influencing visual acuity (VA) after OPG treatment and developed anatomical subtypes correlated with clinical symptoms. Children with OPG who underwent initial partial tumor resection at Beijing Tiantan Hospital from January 2011 to December 2022 were retrospectively analyzed. Multivariate logistic regression and random forest analyses were performed to identify risk factors for post-treatment VA deterioration and a decision tree model was created based on significant factors. A total of 140 patients were enrolled. Multivariate logistic regression analysis identified surgical approach and initial VA as independent predictors of post-treatment VA deterioration (P < 0.05). Surgical approach, initial VA, and extent of tumor resection were the most significant factors for risk assessment and were included in the decision tree model, with surgical approach as the most important "root" node. The model demonstrated good predictive performance, with area under the curve values of 0.75 and 0.66 for the training and test datasets, respectively. A simple anatomical classification was developed, which revealed clinical characteristic differences among OPG types. Meanwhile, a correlation analysis of post-treatment visual deterioration was performed for each of the three anatomical types. This study offers a predictive model for visual outcomes following initial tumor-reduction surgery in OPG patients, which may help in visual outcomes risk stratification. Additionally, the anatomical classification effectively indicates OPG growth direction, offering potential insights into clinical symptoms.

Visual outcome of penetrating ocular trauma among patients visiting University of Gondar comprehensive specialized hospital

Ocular trauma, a preventable public health issue, is one of the common causes of ophthalmic morbidity and monocular blindness worldwide. It can occur in almost any setting and at any age in either sex but largely affects males. The mechanism and type of injury, the extent of damage, and the time-lapse between the occurrence of injury and eye care are among the factors that determine the visual outcome of ocular injuries. This study is designed to assess the clinical profile and visual outcome of patients presenting with penetrating ocular injury. A prospective hospital-based study was conducted among penetrating ocular trauma patients who visited UOG tertiary eye care and training center during the study period. All patients with penetrating ocular trauma who fulfilled the inclusion criteria were included in the study. Data on demography, initial and final visual acuity, type of injury, as well as management, were included in a structured questionnaire. The collected data were processed and analysed using Statistical Packages for the Social Sciences (SPSS) version 25.0. The study included 91 cases of penetrating ocular injuries. The majority of the patients 81.2% were males. The male-to-female ratio was 4.3:1. The left eye was involved in 52.7% of the patients. The median age was 20 years, with an IQR of 10–35. The majority (31.9%) of the cases were in the age range of 5–10 years. nearly half of the study participants (45.1%) sustained the injury at home. The commonest source of injury was wooden sticks 49.5%. Six patients were lost to follow-up at three-month visits. Traumatic cataracts (p = 0.001), and poor initial visual acuity were poor prognostic factors. Still ocular injury is a common cause of monocular blindness. We recommend that more has to be done on the primary prevention and control measures.

Good Initial Visual Acuity in Patients with Macular Edema due to Retinal Vein Occlusion - Management and Outcomes.

The approach to managing patients with retinal vein occlusion (RVO) and cystoid macular edema (CME) with good initial visual acuity (VA) better than 6/12 has not been investigated. This study aimed to evaluate functional and anatomical outcomes of intravitreal treatment and observation in patients with CME due to RVO, who presented with good initial VA. Methods: Multicenter retrospective cohort study. Seventy-nine eyes of 79 patients with CME secondary to RVO and initial VA better than 6/12, either treated with anti-VEGF therapy or observed. Clinical parameters and OCT measures were recorded. Main Outcome Measure: Proportion of patients losing ≥1 line of VA at 12 months. Secondary outcomes: Visual and anatomical results at 12 and 24 months, and correlation between number of injections and VA outcomes. Fifty-three percent of patients maintained VA at month 12. VA of 6/6 - 6/7.5 was maintained in 59% and 57% at 12 and 24 months, respectively. At 24 months, the number of anti-VEGF injections was strongly correlated with VA among patients with BRVO and CRVO. This study marks the first exploration of patients with RVO and initial VA better than 6/12, indicating that most patients sustained good VA, and anti-VEGF treatment maintained and improved VA.

Ocular and adnexal injuries after two major earthquakes in Turkey on February 6, 2023.

This study aimed to determine the forms of ocular and adnexal injuries and to examine the treatment modalities applied after two major earthquakes in Turkey on February 6, 2023. Following the earthquakes, the medical records of 34 patients admitted with emergency ophthalmic complaints to Hatay Training and Research Field Hospital and Etlik City Hospital were retrospectively reviewed. Of these patients, 35 eyes of 34 individuals diagnosed with earthquake-related ocular and adnexal injuries were included in the study. Demographic characteristics were recorded, including ocular and adnexal findings, treatment modalities, and postoperative complications. Of the patients, 16 (47.1%) were female, and 18 (52.9%) were male. The mean age was 37.38 ± 17.3 years. The mean time from the earthquake to the first admission to the hospital was 3.82 ± 1.78 days. Initial and final best-corrected visual acuities (BCVA) were 0.54 ± 0.66 logMAR and 0.22 ± 0.41 logMAR, respectively (p = 0.0003). The initial and final BCVA of 2 eyes was no light perception. The most common forms of ocular/periocular injury associated with earthquakes were eyelid laceration (n:25, 71.4%) and orbital fracture (n:17, 48.6%). The most common accompanied systemic trauma was extremity/rib fractures (38.2). The most frequently performed surgery was the primary repair of the eyelid/canalicular (n:17, 48.6%). While earthquake-related ocular and adnexal traumas are relatively uncommon, understanding the specific injury types, promptly identifying cases requiring urgent intervention, and mastering effective treatment modalities are essential for minimizing the risk of severe permanent visual impairment in these patients.

Management and Clinical Outcomes of Eyes With Posterior Segment Intraocular Foreign Bodies Seen at a Tertiary Referral Center.

This study aimed to identify the prognostic factors regarding the visual and anatomic outcomes of eyes with posterior segment intraocular foreign body (PS-IOFB). The medical records of 95 patients who underwent pars plana vitrectomy and PS-IOFB removal between 2004 and 2021 were retrospectively reviewed. Data on anatomical and visual outcomes, as well as preoperative, intraoperative, and postoperative variables were statistically analyzed. The mean age of the patients was 31.9 ± 12.3 years. The mean follow-up time was 21.9 ± 28.3 months. The median time interval from trauma to IOFB removal was 9 days. In univariate analysis, there was a positive correlation between initial visual acuity (VA) and final VA (P < 0.001). A higher ocular trauma score (OTS) was significantly associated with both anatomical and functional success (P < 0.001). Linear regression analysis showed that OTS was not superior to initial VA in predicting final VA (r = 0.625 vs r = -0.601). Anatomic and functional outcomes were not affected by the injury site, nature of PS-IOFB, or timing of PS-IOFB removal (P > 0.05 for all). Subretinal IOFB location, the need for silicone oil tamponade, and endophthalmitis (P = 0.005, P < 0.001, P = 0.044, respectively) were risk factors for poor visual outcome. The initial VA, the extent of the initial ocular damage, and the presence of endophthalmitis are important prognostic factors for functional success.

Optical coherence tomography characteristics and prognostic predictors of acute macular neuroretinopathy following SARS-CoV-2 infection.

To analyze the characteristics of optical coherence tomography in acute macular neuroretinopathy (AMN) following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and discuss the prognostic predictors. Patients with AMN following SARS-CoV-2 infection were divided into two groups according to the presence or absence of hyperreflective outer nuclear layer (ONL) lesion involving the fovea. The first visit included 14 eyes in the fovea-involved group and 20 eyes in the no fovea-involved group. Ellipsoid zone (EZ) hyporeflection and interdigitation zone (IZ) interruption were detected in all eyes. Other common manifestations were myoid zone (MZ) hyperreflection (76.5%), ONL hyperreflection (73.5%), outer plexiform layer (OPL) thickening (64.7%), and EZ interruption (50%). The follow-up period was 48.4 ± 55.3 days. At the last visit, 12 eyes were in the fovea-involved group and 13 eyes in the no fovea-involved group. IZ interruption was detected in all eyes. Other common manifestations were EZ hyporeflection (92.0%), ONL atrophy (40.0%), OPL thickening (36.0%), OPL linear (32.0%), and MZ hyperreflection (32%). The improvement of visual acuity (VA) was -0.5 ± 0.5 and -0.2 ± 0.4 in the fovea-involved group and the no fovea-involved group, respectively, with a statistically significant difference between them (P = 0.045). Initial VA, initial cotton wool spot, initial ONL cyst, final ONL cyst, and final OPL linear were associated with final VA (P = 0.000, P = 0.029, P = 0.044, P = 0.049, P = 0.049, respectively). In the early stage of AMN following SARS-CoV-2 infection, IZ interruption and EZ hyporeflection were the most common manifestations, and pathology of IZ was more serious than that of EZ. Subsequently, OPL and ONL atrophied, and ONL atrophied faster. Regardless of whether hyperreflective ONL involved the fovea, VA improved, with a more noticeable improvement found in the fovea-involved group. The presence of initial ONL cyst and initial cotton wool spot, rapid atrophy of OPL, and poorer initial VA indicating poorer VA outcome.
