Visual Outcome In Patients Research Articles

Acute retinal necrosis: clinical features, management and outcomes.

To evaluate the clinical features, treatment, and visual outcome of patients with acute retinal necrosis (ARN). The data of patients were retrospectively reviewed. Factors associated with visual loss and factors affecting the risk for retinal detachment (RD) development were evaluated. Twenty-four eyes of 24 patients (7 female/17 male, mean age 43.7years, mean follow-up period 31.0months) were included. In ocular fluid samples of 15 (83%) out of 18 eyes, polymerase chain reaction (PCR) tests were positive for herpes simplex virus (seven eyes; 39%), varicella zoster virus (six eyes; 33%), cytomegalovirus (one eye; 6%), and adenovirus (one eye; 6%). Central retinal occlusive vasculitis was observed in three (13%) eyes. Systemic antiviral therapy was given to all patients, and additional intravitreal ganciclovir was administered in seven eyes (29%). The most common complication was RD (46%). There was no statistically significant difference in the frequency of RD between herpes simplex virus- and varicella zoster virus-positive patients (p = .617). The rate of RD was similar in eyes undergoing prophylactic laser photocoagulation (LPC), eyes undergoing vitrectomy + LPC, and eyes not undergoing LPC (p = .237). The number of eyes with final visual acuity below 20/200 was significantly higher in eyes with RD than without RD (p = .047). Prophylactic LPC and vitrectomy did not show clear benefits in terms of preventing RD development. RD was the most common complication and a major factor for a poor visual prognosis.

The First-Year Variation in Central Retinal Thickness Predicts Legal Blindness in Patients with Neovascular Age-Related Macular Degeneration

Introduction: Due to its progressive nature, early evaluation and timely prediction of legal blindness are important in patients with neovascular age-related macular degeneration (nAMD). We examined the association between early-stage variation in central retinal thickness (CRT) and long-term visual outcomes in patients with nAMD. Methods: We included 103 nAMD patients who were administered anti-vascular endothelial growth factor (anti-VEGF). Participants were considered qualified if they were (1) 50 years and older, (2) treatment-naïve, (3) received standard anti-VEGF treatment and had complete baseline information. We further excluded patients with less than 1-year follow-up data and those who experienced best corrected visual acuity ≤35. Early-stage variability in CRT was measured as the first-year coefficient of variability (CV) of CRT. Patients were then classified into the high-variability and low-variability groups according to the X-tile. A product-limit plot was used to demonstrate the differences and tested with the log-rank test. The association between first-year variability and visual outcomes was quantified using Cox regression models. Time-to-event primary endpoint was the overall visual preservation (OVP) rate, defined as the time from the first injection to legal blindness, i.e., best corrected visual acuity ≤35 Early Treatment Diabetic Retinopathy Study (ETDRS) letters. Results: A threshold of 20% of first-year CV in CRT was used to categorize 76 qualified patients into high variability (35, 46.1%) and low variability (41, 53.9%). The 5- and 10-year OVPs for patients with high versus low variability were 76% versus 48% and 59% versus 22%, respectively. High early-stage CRT variability showed a significantly higher risk of legal blindness. Even after adjusting for the demographic and clinical features, the variability remained significant (HR = 2.39, 95% CI: 1.20–4.78). Conclusion: First-year variability of CRT was predictive of long-term visual outcomes in patients with nAMD, and 20% of the variability could be used as a clinically convenient threshold to qualitatively classify patients into high- and low-variability groups. The current study is important for identifying high-risk populations and for long-term disease management.

Demographic pattern and visual outcome in patients with open globe injury

: This study aimed to assess the demographic and clinical characteristics, prognostic factors, and visual outcomes of open globe injury on the repair. This was a retrospective cross-sectional study including all patients who underwent repair surgery following open globe injury and are on regular follow-up visits postoperatively in a tertiary eye hospital from 1st July to 31st December 2021. Patients were divided into two groups. Group A include OGI patients undergoing repair within 24 hours, and Group B includes OGI patients who underwent repair after 24 hours of injury. All the study patients were studied in detail, including the Presenting features, mechanism of injury, preoperative and postoperative visual acuity, demographic data, and postoperative complications. This study studied a total of 100 patients (46 in group A and 54 in group B). Male predominance (>70%) was seen in both groups. In both groups, the highest number of patients (61% in group A and 52% in group B) were in ≤18 years of age. In both groups, the majority of OGI (52% in group A and 61% in group B) were Iron induced. In groups A and B, Zone I is affected chiefly, about 85% and 81%, respectively. Most OGI patients were admitted to the hospital with severe low vision on VA examination, about 54% and 63% in Group A and B, respectively. At three months of postoperative follow-up, BCVA was significantly improved In Group A than in Group B (p-value 0.05). 80% patients improved to normal vision in group A compared to 50% in group B. Open globe injuries should be repaired as soon as possible, even within hours. Initial visual acuity remains the strongest predictor of outcome; however, delay to primary repair reduces final visual acuity.

Clinical, demographic characteristics, and treatment protocols of optic neuropathies: Three-year follow-up experiences from a tertiary hospital in Turkey.

Background: This study was conducted to review the demographic and clinical characteristics, treatment protocols, and visual outcomes of patients with optic neuropathy. Methods: This historical cohort study analyzed the clinical features of 91 patients with optic neuropathy followed up for three years at a university hospital in Turkey. Results: Non-arteritic anterior ischemic optic neuropathy (NA-AION) was the most common group among the optic neuropathy subgroups (47.2%), and optic neuritis (ON) was the second most common group (38.5%). The mean age of symptom onset for NA-AION was 64.97 ± 12.15 years, significantly higher than the mean age of onset for ON (40.28 ± 15.52 years). Most of the patients with NA-AION had at least one systemic disease causing microangiopathy [51.1% had diabetes mellitus (DM), 33.3% had hypertension (HTN)]. Among the patients with ON, 51.4% were idiopathic, and 25.7% were multiple sclerosis (MS)-related ON cases. Patients with ischemic optic neuropathy (ION), ON, and traumatic optic neuropathy received pulse intravenous (IV) corticosteroids, and eleven patients with NA-AION received acetylsalicylic acid (ASA) therapy in addition to corticosteroids. There was a statistically significant increase in visual acuity in NA-AION and ON groups (P = 0.019). It was observed that the cases of ON peaked in the winter months in Turkey. Conclusion: In the differential diagnosis between NA-AION and idiopathic ON, the presence of one or more vascular systemic diseases and mean age may be the main factors. IV steroid treatment given to patients with NA-AION in the acute phase may significantly improve visual acuity.

Visual Outcomes and Optical Coherence Tomography Biomarkers of Vision Improvement in Patients With Leber Hereditary Optic Neuropathy Treated With Idebenone

To assess the relationship of demographics, clinical characteristics and structural optical coherence tomography (OCT) findings to long-term visual outcomes in patients with Leber hereditary optic neuropathy (LHON) treated with idebenone. Retrospective, interventional, noncomparative clinical cohort study. In this study, a total of 17 participants (34 eyes) with LHON treated with idebenone therapy within 1 year after disease onset and 2 years (24 months) of regular follow-ups were retrospectively enrolled. At baseline, structural OCT volume scans of the macula and optic nerve were reviewed to measure metrics reflecting neuronal loss (ie, macular ganglion cell and inner plexiform layer [GC-IPL] and peripapillary retinal nerve fiber layer [RNFL] thicknesses). Stepwise multiple regression analyses were computed to assess associations between final best-corrected visual acuity (BCVA) at 2 years and change in BCVA from baseline at 2 years as dependent variables with demographics, clinical characteristics, and OCT metrics at baseline (visit before the initiation of treatment). The BCVA was 1.6±0.8 logMAR (Snellen VA of ∼20/800) at baseline (visit before the initiation of treatment) and 1.0±0.7 logMAR (Snellen VA of 20/200) at the 2-year follow-up visit (P < .0001). Mean±SD change in BCVA from baseline at 2 years was -51.9%±35.9%. In multivariable analysis, the strongest associations with final BCVA were with baseline BCVA (P=.012), superior macular GC-IPL thickness (P=.044), superotemporal macular GC-IPL thickness (P=.010), and inferotemporal macular GC-IPL thickness (P=.015). Similarly, the strongest associations with delta BCVA were with superior macular GC-IPL thickness (P=.045), superotemporal macular GC-IPL thickness (P=.047), and inferotemporal macular GC-IPL thickness (P=.030). We identified OCT biomarkers associated with long-term (ie, 2-year) visual outcomes in patients with LHON treated with idebenone therapy in the first year after disease onset. Thinning of the GC-IPL in the superior and temporal parafoveal regions was associated with worse long-term visual outcomes in these patients.

Clinical Audit on Badminton-Related Ocular Injuries in a Tertiary Hospital in Malaysia.

Background Badminton-related ocular injuries are among the commonest causes of blunt trauma to the eye, which can lead to significant damage to the ocular structures. This study aimed to assess the clinical presentations, complications, and visual outcomes of patients who sustained ocular injuries related to badminton treated in a single tertiary center in Malaysia. Materials and methods A retrospective clinical audit was conducted in Hospital Universiti Sains Malaysia (HUSM), Malaysia, involving patients diagnosed with ocular injuries related to badminton, either as players or spectators, between January 1, 2003 and December 31, 2017. The demographic data, mechanism of injury, and clinical presentation were recorded. In addition, visual acuity, anterior and posterior segment, and intraocular pressure (IOP) measurements were recorded at the initial presentation and at the present recruitment period. Management at the initial presentation was also obtained and recorded. The final visual outcome and complications were based on the finding of the most recent follow-up. Visual acuity was categorized as follows: mild or no visual impairment (6/18 or better), moderate and severe visual impairment (<6/18 and worse). Results A total of 23 patients (23 eyes) were included in this clinical audit. The average age was 24 years, with a range of 6-56 years, with the highest incidence occurring at the age of 20 years old and younger. The majority of the injuries were sustained during the single-player game. All the injuries were caused by shuttlecock hits. In 18 cases (78%), the trauma was caused by an opponent, in four cases (17%) by a partner, and in one case involving a bystander. Most of the patients in this series were not using any protective eyewear while playing the game 96% (22). Most injuries (22 eyes) involved the anterior segment, with hyphaema as the commonest clinical presentation. The mean IOP at presentation was 23.5 (11.2) mmHg. Angle recession was detected as early as one-week post initial presentation in 17 eyes. Commotio retinae (5 eyes) and vitreous hemorrhage (4 eyes) were the common posterior segment findings. There were eight eyes with visual acuity of worse than 6/18 at the initial presentation, but only three eyes had poor final visual acuity. There was a statistically significant improvement in visual acuity at the last follow-up compared to the initial presentation (Fisher's exact test) (p=0.032). Conclusion Ocular injuries related to badminton is common and cause a detrimental effect on the long-term visual outcome. Traumatic hyphaema and commotio retinae are the most common presenting signs related to poor visual outcomes. Therefore, protective eyewear and promoting awareness of badminton-related ocular injuries are essential to prevent monocular blindness in young adults.

Pars plana vitrectomy and subretinal tissue plasminogen activator for large exudative submacular hemorrhage: a case series

BackgroundTo evaluate anatomical and functional outcomes of patients with large submacular hemorrhage (SMH) who treated by pars plana vitrectomy (PPV) in combination with subretinal tissue plasminogen activator (TPA) injection, intraocular gas tamponade, and with additional post-operative interventions.MethodsMedical records of 9 patients who presented with large SMH secondary to age-related macular degeneration (AMD) and underwent PPV, subretinal TPA injection, and gas tamponade at Chiang Mai university hospital between January 2012 and January 2020 were reviewed. Collected data included preoperative visual acuity (VA), SMH extent and duration, intraoperation and post-operation complications, post-operative anatomical and VA responses, and the need for administer post-operation additional treatments.ResultsOverall, five patients were male and four patients were female with a mean (SD) age of 66.9 (7.7) years and a mean (SD) follow-up of 21.1 (16.1) months. A mean (SD) duration of SMH was 15.1 (10.9) days with a mean (SD) extent of SMH was 6.2 (3.4) disc diameters. At 1-month post-operation, complete SMH displacement was noted in eight (88.9%) patients. The mean (SD) VA significantly improved from LogMAR 1.9 (0.4) to 1.1 (0.4), (P = 0.004). During follow-up, eight patients (88.9%) were given additional therapy (anti-vascular endothelial growth factor (anti-VEGF) monotherapy, photodynamic therapy, or in combination). At final follow-up, a mean (SD) LogMAR VA of 0.9 (0.4) was significantly improved compared to baseline (P = 0.004). For intra- and post-operation complications, none developed intraoperative retinal break and retinal detachment.ConclusionsVitrectomy with subretinal TPA injection, intraocular gas tamponade, and additional post-operation treatments provide benefit for anatomical and visual outcomes for patients with large SMH. It may consider as one of effective treatment in this group of patients.

Visual, Anatomic Outcomes, and Natural History of Retinal Nerve Fiber Layer Schisis in Patients Undergoing Epiretinal Membrane Surgery

To evaluate the anatomic and visual outcomes of patients with idiopathic epiretinal membranes (ERMs) complicated by schisis of the retinal nerve fiber layer (sRNFL) in routine clinical practice. Retrospective case-control study. Patients undergoing idiopathic ERM surgery at Cole Eye Institute from 2013 to2021. Patients were grouped by the presence or absence of sRNFL before surgery. Preoperative and postoperative data were collected regarding visual acuity (VA), changes in central subfield thickness (CST) over time, and presence of cystoid macular edema. Frequency of sRNFL in patients undergoing idiopathic ERM surgery. Overall, 48 (53.9%) of 89 patients presented with sRNFL. Schisis of the retinal nerve fiber layer patients presented with significantly decreased VA compared with those without (58.63 ± 12.48 vs. 67.68 ± 7.84 ETDRS letters, P < 0.001, respectively). At the final follow-up after ERM removal, there was no significant difference in final VA in patients with sRNFL compared with those without (71.16 ± 2.93 vs. 74.11 ± 2.76, P=0.467). At presentation, patients with sRNFL had greater CST than those without (454 ± 10.01 vs. 436 ± 0.23, P= 0.23). This difference persisted at the 90-day follow-up after ERM removal (402 ± 8.08 vs. 375 ± 10.19 μm, P= 0.043). The resolution of sRNFL was reported at postoperative week 1 in 30 (96.7%) of 31 cases. Schisis of the retinal nerve fiber layer is a microstructural feature in > 50% of idiopathic ERMs in routine clinical practice and carries visual significance on presentation and anatomic significance postoperatively.

Intra-arterial Thrombolysis for Acute Retinal Ischemia: A Retrospective, Observational, Cohort Study.

To determine whether intra-arterial thrombolysis (IAT) within 16 hours after the onset of symptoms is feasible and associated with better visual outcomes in patients with acute retinal ischemia (ARI). The retrospective cohort study was performed from January 2014 to December 2021 in the Xuanwu Hospital of Capital Medical University. Patients with ARI who initially presented visual acuity of 20/100 or worse were screened in the study. Visual end points were evaluated at one week and at final visit after treatment. Serious adverse events were recorded during operation and within 1 week after IAT treatment. The amount of clinically significant visual improvement (≥0.3 logarithm of the minimum angle of resolution) in the IAT group was significantly higher than that in the conservative treatment group at one week after the treatment (47.8% vs 16.7%; P = 0.014) and at final visit (52.2% vs 20%; P = 0.014). After controlling confounding factors, ARI treatment was the only factor significantly associated with the amount of clinically significant visual improvement (OR, 4.364; 95 CI, 1.298-14.667; P = 0.017). A patient (4.3%) experienced retinal hemorrhage without symptom within 1 week after IAT treatment. No patients experienced new symptomatic cerebral infarction, intracranial hemorrhage, TIA, artery dissection, vascular perforation, and distal embolization during operation and within 1 week after IAT treatment. IAT may be associated with better visual improvement within 16 hours after the onset of symptoms. Besides, IAT is feasible and associated with a low risk of periprocedural complications for ARI. This study will aid in feasibility testing and sample size calculations in advance of future, fully-powered efficacy studies for ARI.

ISOLATED RETINAL VASCULITIS: Prognostic Factors and Expanding the Role of Immunosuppressive Treatment in Retinal Vasculitis Associated With Positive QuantiFERON-TB Gold Test.

To identify prognostic factors for poor visual outcomes in patients with isolated retinal vasculitis and to elucidate the outcome of immunosuppressive treatment without the use of antituberculosis drugs for patients with retinal vasculitis associated with a positive QuantiFERON-TB Gold In-Tube (QFT) test. A retrospective chart review was performed of patients presenting with retinal vasculitis. After the diagnosis of active retinal vasculitis had been confirmed by fluorescein angiography and other possible causes of retinal vasculitis had been excluded, patients were categorized into two groups by their QFT result. Potential associated factors between the poor and good visual outcome groups were statistically analyzed by the chi-square test and logistic regression model with generalized estimating equations. Seventy-three eyes (48 patients) were enrolled in this study. After univariate analysis, multivariate logistic regression analysis was performed and revealed that logMAR visual acuity at the initial visit ( P = 0.01) and outer retinal disruption ( P = 0.03) were the two factors significantly associated with poor visual outcomes. Systemic corticosteroids were administered without the use of antituberculosis drugs to all 16 cases of presumed tuberculous retinal vasculitis associated with positive QFT (26 eyes), 10 (63%) of whom were given nonsteroidal immunosuppressive drugs and achieved inflammatory control and treatment success. Risk factors leading to poor visual outcome in patients with isolated retinal vasculitis have been identified. Immunosuppressive treatment without antituberculosis drugs seems to be a promising regimen for selected patients with presumed tuberculous retinal vasculitis under vigilant care.

Investigating Determinants and Evaluating Deep Learning Training Approaches for Visual Acuity in Foveal Hypoplasia

To describe the relationships between foveal structure and visual function in a cohort of individuals with foveal hypoplasia (FH) and to estimate FH grade and visual acuity using a deep learning classifier. Retrospective cohort study and experimental study. A total of 201 patients with FH were evaluated at the National Eye Institute from 2004 to2018. Structural components of foveal OCT scans and corresponding clinical data were analyzed to assess their contributions to visual acuity. To automate FH scoring and visual acuity correlations, we evaluated the following 3 inputs for training a neural network predictor: (1) OCT scans, (2) OCT scans and metadata, and (3) real OCT scans and fake OCT scans created from a generative adversarial network. The relationships between visual acuity outcomes and determinants, such as foveal morphology, nystagmus, and refractive error. The mean subject age was 24.4 years (range, 1-73 years; standard deviation = 18.25 years) at the time of OCT imaging. The mean best-corrected visual acuity (n= 398 eyes) was equivalent to a logarithm of the minimal angle of resolution (LogMAR) value of 0.75 (Snellen 20/115). Spherical equivalent refractive error (SER) ranged from-20.25 diopters (D) to+13.63 D with a median of+0.50 D. The presence of nystagmus and a high-LogMAR value showed a statistically significant relationship (P < 0.0001). The participants whose SER values were farther from plano demonstrated higher LogMAR values (n= 382 eyes). The proportion of patients with nystagmus increased with a higher FH grade. Variability in SER with grade 4 (range,-20.25 D to+13.00 D) compared with grade 1 (range,-8.88 D to+8.50 D) was statistically significant (P < 0.0001). Our neural network predictors reliably estimated the FH grading and visual acuity (correlation to true value > 0.85 and > 0.70, respectively) for a test cohort of 37 individuals (98 OCT scans). Training the predictor on real OCT scans with metadata and fake OCT scans improved the accuracy over the model trained on real OCT scans alone. Nystagmus and foveal anatomy impact visual outcomes in patients with FH, and computational algorithms reliably estimate FH grading and visual acuity.

Incidence and visual outcomes of acute endophthalmitis post intravitreal injection of anti-vascular endothelial growth factors in a single referral center.

To describe the incidence and factors predicting visual outcome in patients with infectious endophthalmitis following intravitreal anti-VEGF injection. Retrospective, single-site, cohort study. Patients with acute endophthalmitis within 6weeks of intravitreal anti-VEGF injection who were referred to our practice after inciting injection or were injected by us between January 2010 and July 2017 were included. All patients received intravitreal antibiotics with either vitreous/anterior chamber tap (TAP) or pars plana vitrectomy. Visual outcomes pre/post treatment, baseline variables (age, gender, ocular disease) and cultures results were studied. Seventy eyes of 69 patients were included. Presenting VA was the strongest factor associated with final visual outcome after adjusting for other variables including culture status and baseline VA (p = .0002). Cultures were positive in 62.8% of eyes and were associated with worse visual outcome (p = .0087). Growth of Streptococcus or microorganisms other than coagulase negative Staphylococci (CNS) was also associated with worse prognosis, regardless of baseline and presenting VA (p = .0002). The crude incidence of post-injection endophthalmitis was 0.028% in our practice (40 eyes in 143,628 injections) during the study time. No significant difference was found between pre-filled bevacizumab versus ranibizumab or aflibercept drawn from a vial. In a large, single center, retrospective study, the incidence of acute endophthalmitis post anti-VEGF injection was relatively low. Worse visual acuity at presentation of endophthalmitis and growth of Streptococcus or organisms other than CNS were associated with the worst visual outcomes.

The Predictive Value of Computed Tomography Findings for Poor Visual Outcome in Traumatic Eye Injury.

Background The prognosis of visual outcome is important for patients and healthcare providers and guides proper decision-making in traumatic eye injury. In this study, we have evaluated the predictive value of computed tomography (CT) scan findings for poor visual outcomes in patients with traumatic eye injuries. Methods In a retrospective survey, documents of 200 patients with traumatic eye injury who underwent a diagnostic orbital CT scan were reviewed. Disorganized or collapsed globe, intraocular foreign body or gas, increased or decreased anterior chamber size, hemorrhage in the anterior or posterior chamber, crystalline or intraocular lens dislocation, posterior sclera thickening, globe borders haziness, orbital fracture, orbital hemorrhage, and foreign body, optic canal, and optic nerve injuries are the diagnostic clues for eye injury in CT scan. The predictive value of CT scan findings for poor visual outcome was calculated by sensitivity, specificity, accuracy, predictive values, hazard ratios, and binary logistic regression model. Results The sensitivity, specificity, accuracy, and positive predictive values showed to be high. However, there was a low negative predictive value of CT findings for the prediction of poor vision. Among the investigated factors, disorganized/collapsed globe (HR 47.72, CI 6.13–371.62), increased/decreased anterior chamber size (HR 5.04, CI 2.57–9.88), hemorrhage in anterior/posterior chamber (HR 3.58, CI 1.900–6.774/3.62, CI 1.90–6.89), globe borders haziness (HR 3.06, CI 1.33–7.01), orbital foreign body (HR 3.66, CI 1.11–12.05), and optic canal/nerve injury (HR 21.62, CI 4.73–98.78) reached the statistical significance for increasing the hazard ratio for poor visual outcome in patients with a traumatic eye injury. Logistic regression analysis showed only evidence for disorganized/collapsed globe and optic canal/nerve injury in orbital CT scan as independent predictive factors for poor visual outcome. Conclusion CT scan findings can be used as prognostic factors for visual outcomes in patients with a traumatic eye injury.

CLINICAL PROFILE OF PATIENTS OF CENTRAL SEROUS CHORIORETINOPATHY PRESENTED TO THE TERTIARY HEALTH CARE CENTRE

Purpose:To study the clinical profile and relationship between time of presentation and visual outcome in patients with central serous chorioretinopathy . Material and Method: Total 100 eyes of 50 patients were selected for the study who presented with complaints of blurring and or sudden painless loss of vision ,out of which 10 eyes of 5 patients were excluded due to corneal opacity, diabetic retinopathy, hypertensive retinopathy ,cataract and retinal detachment, retinitis pigmentosa. Total 90 eyes of 45 patients were included in the study and divided into two groups according to the time of presentation :1) Group 1-Within 15 days of onset of symptoms.2) Group 2 -After 2 months of onset of symptoms. Result:Group 1 patients showed the better visual outcome(BCVA 6/36-6/9) than the group 2 patients(BCVA 6/36-6/24). Conclusion: The time of presentation to the tertiary care centre was the major factors influence the visual outcome in patients with CSR.

Visual outcomes of toxic optic neuropathy secondary to Ethambutol: A retrospective observational study from India, an endemic country.

Ethambutol (EMB) is one of the first-line drugs used for treating tuberculosis. Vision loss due to optic nerve toxicity is a well-known potential side effect of the drug. Our aim was to evaluate the clinical features and visual outcomes of patients with EMB optic neuropathy (EON). A retrospective, observational, single-center study of all patients who were diagnosed to have EON during January 2017-December 2019 was done. All these patients were screened in the Department of Neuro-ophthalmology at a referral tertiary eye care institution in India. Clinical features, visual outcomes, and neuroimaging findings of these patients were analyzed. Two hundred and fifty-six eyes of 128 patients were included. Of these, 73 were male and 55 were female. Mean age was 50.55 ± 15 years. Mean visual acuity at presentation was 1.12 ± 0.45 logarithm of the minimum angle of resolution (logMAR). One hundred and forty three eyes had normal optic disk on presentation, 111 had disk pallor, and two eyes had disk edema. The most common field defect was central/paracentral scotoma (26.2%) followed by temporal defects (24.6%). Magnetic resonance imaging (MRI) brain and orbit showed optic nerve signals in 19.6% and chiasmal signals in 5.2%. At the final follow-up, a ≥2-line vision improvement was noted in 161 eyes (62.9%), which was statistically significant. Multiple prognostic factors were analyzed to predict the visual recovery of EON. We observed that patients presenting with visual acuity worse than 6/60 had poor visual outcome and long duration of follow-up showed better visual recovery, proving the possibility of a gradual recovery pattern of EON. Interestingly, we found in our study that the chances of favorable visual outcome were directly proportionate to early diagnosis and cessation of EMB.

Ocular syphilis resurgence in an urban underserved community in the United States.

To evaluate the clinical characteristics, demographics, and visual outcomes of patients with ocular syphilis at an urban hospital to increase awareness and assist in earlier diagnosis and treatment of the resurgent disease. A retrospective chart review was performed on patients with ICD-9 and ICD-10 diagnosis codes correlating with syphilis or syphilis-related ocular diseases between 2010 and 2019. Variables evaluated included age, gender, race, vision, ocular findings, human immunodeficiency virus (HIV) status and men who have sex with men status, recreational drug and alcohol use. Ocular syphilis was diagnosed in 40 patients (53 eyes) of a total of 229 patients who tested positive for syphilis via serum and/or cerebrospinal fluid treponemal testing from 2010-2019. Among patients with ocular syphilis, most patients were males, aged 45 or above and Black, and had no diagnosed HIV infection. Approximately 50% patients had 20/40 vision or better. Nearly 50% had non-granulomatous anterior uveitis as their initial presentation, and 49% of patients had involvement of the posterior segment. Neovascular glaucoma (5.7%), papillitis (7.5%), vasculitis (5.7%), and retinal detachment (5.7%) were rarer presentations of the disease and were associated with a poorer visual prognosis. Given the increased prevalence and protean manifestations of syphilis, early diagnosis and treatment are paramount. More studies on ocular syphilis are warranted to understand this resurging disease.

The Long-term Outcomes of Central Retinal Vein Occlusion and Factors Associated with Resolution of Macular Edema

Purpose: To report the long-term outcomes of patients with macular edema (ME) secondary to central retinal vein occlusion (CRVO) and to explore the ME incidence and factors associated with ME resolution.Methods: We retrospectively studied patients with ME secondary to CRVO. The visual acuity at baseline was compared to that at the final visit. The incidence and timing of ME resolution during treatment were evaluated and the visual outcomes of patients who did and did not experience ME resolution were compared. We also identified factors predictive of ME resolution.Results: We included 79 patients; the mean follow-up time was 50.1 ± 14.3 months. The mean logarithm of the minimal angle of resolution (logMAR) of visual acuity was 0.94 ± 0.75 at diagnosis and 1.00 ± 0.84 at the final visit (p = 1.000). A logMAR visual loss of 0.3 or greater was noted in 28 patients (35.4%). During follow-up, ME resolution was evident in 40 eyes (50.6%) at a mean of 16.9 ± 17.4 months. Visual improvement was greater in patients who evidenced ME resolution than in those who did not (p &lt; 0.001). The ME resolution rate was higher in patients younger than 60 years (p = 0.039) and in those who lacked subretinal fluid at diagnosis (p &lt; 0.001).Conclusions: In patients with ME secondary to CRVO, the risk of long-term recurrent ME was higher in older patients and those evidencing subretinal fluid at diagnosis indicating that such patients require close follow-up and aggressive treatment.

Socioeconomic disadvantage and impact on visual outcomes in patients with viral retinitis and retinal detachment

While socioeconomic disparities impact clinical care and patient outcomes, their impact on the anatomic and visual outcomes of retinal detachment in patients with viral retinitis is unstudied. This case series included 18 eyes in 18 patients from a single academic institution between January 1, 2008 and December 31, 2018. Patient characteristics including age, sex, race, ethnicity, insurance, immunosuppression, viral retinitis, retinal detachment, retinal detachment repair, visual and anatomic outcomes, missed appointments, and Area Deprivation Index [ADI] were collected. The low-ADI group, indicating less socioeconomic disadvantage, was comprised of twelve patients with national ADIs less than 38, and the high-ADI group of six patients with national ADIs greater than 38. High-ADI patients tended to be younger (average age 38.0 versus 51.3; P = 0.06), of female sex (P = 0.03), and had more missed appointments (median 11.0 vs 0; P = 0.002). A similar number of patients in both the high-ADI and low-ADI groups underwent pars plana vitrectomy alone or pars plana vitrectomy with scleral buckle. Visual acuity was similar in the high-ADI group than in the low-ADI group at baseline, but worse at the final follow-up visit (P = 0.004). Post-operative and final visit ocular hypotony were more common in the high-ADI group (P = 0.02). In our series, socioeconomic disadvantage negatively affects the visual outcomes in patients with viral retinitis associated-retinal detachments. These factors should be considered by ophthalmologists when treating these patients.
