Vitrectomy versus scleral buckle for retinal detachment without posterior vitreous detachment

To compare the effectiveness and safety of scleral buckling and pars plana vitrectomy in treating retinal detachment without posterior vitreous detachment. A total of 88 eyes of 83 patients with retinal detachment without prior posterior vitreous detachment were investigated retrospectively. Group A comprised patients who underwent scleral buckling (n = 47) and Group B (n = 36) patients who were treated with pars plana vitrectomy. Anatomical success, postoperative visual acuity, and ocular adverse events were evaluated. The primary and final anatomical success rate showed a nonsignificant difference (p = 0.465 and p = 0.37 respectively). No significant difference was observed in the reoperation rate or development of epiretinal membrane between the groups (p = 0.254 and p = 0.254 respectively). However, scleral buckling resulted in significantly better visual acuity at the last follow-up (0.12 ± 0.23) compared to pars plana vitrectomy (0.37 ± 0.46, p = 0.001). The incidence of cataract progression was also significantly higher in the pars plana vitrectomy group (46%) compared to the scleral buckling group (10%, p < 0.001). Scleral buckling and pars plana vitrectomy show similar success rates in treating retinal detachment without vitreous detachment. However, due to less cataract progression and better visual acuity outcomes, scleral buckling is recommended for these cases. Determining vitreous status before surgery is crucial for optimal outcomes.

Microinvasive intrascleral double continuous suture repair surgery for cyclodialysis clefts.

The traditional suturing method for cyclodialysis cleft usually requires an incision in the sclera for direct suturing, resulting in greater damage and a high risk of postoperative complications. The purpose of this work is to propose a newly intrascleral double continuous suture repair technique for the treatment of cyclodialysis clefts. Seven patients with cyclodialysis cleft underwent microinvasive intrascleral double continuous suture repair surgery to restore the attachment of the detached ciliary body to the sclera without scleral incision. All operations were performed by the same surgeon. Preoperative and postoperative visual acuity (VA), intraocular pressure (IOP), slit lamp and corneal examination results, ultrasound biomicroscopy (UBM) and optical coherence tomography (OCT) results were recorded. Closure of the cyclodialysis cleft was achieved in 7 eyes and no obvious complications occurred after the operation. Intraocular pressure increased from preoperatively 6.8 ± 1.35 mmHg (range: 4.8-8.0 mmHg) to postoperatively 12.5 ± 4.0 mmHg (range: 8.0-20.0 mmHg) (paired sample T test, P < 0.01). Best-corrected Snellen visual acuity improved from preoperatively range 20/2000-20/63 to range 20/200-20/25 at final follow-up. In short, intrascleral double continuous suture repair surgical is safe and effective in treating cyclodialysis cleft, with minimal surgical trauma.

Non-syndromic OTX2-associated pattern dystrophy: a 10-year multimodal imaging study

PurposeTo report novel multimodal imaging features and long-term follow-up of Orthodenticle Homeobox 2 (OTX2)-associated pattern Gdystrophy.MethodsA 14-year-old boy referred with glaucoma suspect and macular pigmentation underwent fundus autofluorescence imaging, optical coherence tomography, fluorescein and indocyanine green angiography, visual field test, microperimetry and electrophysiology over a ten-year period. Next-generation sequencing panel identified a de novo heterozygous likely pathogenic OTX2 variant, c.259G>A, [p.(Glu87Lys)].ResultsVisual acuity was 20/40 OD and 20/30 OS. Examination showed bilateral enlarged optic nerve heads and increased disc cupping, multiple cilioretinal arteries, a pigmentary maculopathy with stellate-shaped region of hypoautofluorescence, shallow serous macular detachment, subretinal deposits and temporal avascular retina. Angiography showed no source of leakage and absence of retinal neovascularisation despite extensive peripheral non perfusion. Electrophysiological assessments demonstrated mild progressive rod and cone pathway abnormalities, reduced light-adapted b:a ratio, and reduced Arden ratio on electro-oculogram. Ten-year follow-up confirmed a stable disease course despite persistent submacular fluid. There was no associated pituitary structural abnormality or dysfunction.ConclusionsThis case study contributes to further understanding of OTX2-associated pattern dystrophy, highlighting its stability over 10 years. Further investigation into inter-individual and intrafamilial variability is warranted.

Endophthalmitis Caused by Bacillus cereus: Clinical Characteristics, Outcomes and Antibiotic Susceptibility.

Bacillus cereus endophthalmitis is a severe vision-threatening disease. This study aimed to analyze the clinical characteristics, antibiotic susceptibility, and risk factors for poor final visual acuity (VA) and enucleation or evisceration (ENEV) outcomes of B. cereus endophthalmitis patients. We retrospectively reviewed 52 cases (52 eyes) of culture-proven B. cereus endophthalmitis at Zhongshan Ophthalmic Center from January 2013 to December 2023. The mean age of the patients was 38.1 ± 20.1 years, and males composed the majority (90.4%) of the sample size; laborers (32.7%) and farmers (19.2%) were the primary occupations of the patients. All cases were caused by ocular trauma. Forty-one of 51 eyes (80.4%) had a final VA worse than the ability to count fingers (CFs), and 15 of the 52 total eyes (28.8%) underwent ENEV. Binary logistic forward (LR) regression analysis demonstrated that red eye (odds ratio [OR], 13.13; 95% confidence interval [CI], 1.58-108.80; p = 0.017), eye pain (OR, 22.87; 95% CI, 1.00-522.72; p = 0.050), and corneal edema/ulcer (OR, 13.13; 95% CI, 1.58-108.80; p = 0.017) were significant risk factors for poor VA outcomes. Conjunctival sac purulent discharge (OR, 10.08; 95% CI, 2.11-48.12, p = 0.004) and white blood cell (WBC) count (OR, 1.35; 95% CI, 1.06-1.72, p = 0.016) were significant risk factors for ENEV outcomes. B. cereus showed susceptibility rates of 100.0% to vancomycin and ofloxacin; 98.0% to levofloxacin; 93.3% to ciprofloxacin; 87.5% to imipenem; and 78.9% to tobramycin. The susceptibility to azithromycin and clindamycin was 66.7% and 50.0%, respectively. In contrast, B. cereus was resistant to penicillin (susceptibility at 3.8%), cefuroxime (5.6%), and cefoxitin (37.1%).

Treat-and-Extend Versus Pro re nata Regimens of Ranibizumab and Aflibercept in Neovascular Age-Related Macular Degeneration: A Comparative Study from Routine Clinical Practice.

Anti-vascular endothelial growth factor (VEGF) is generally given using pro re nata or "treat-and-extend" (T&E) regimens for neovascular age-related macular degeneration (nAMD). Randomized clinical trials have reported that T&E is superior to Pro re nata (PRN), but results from clinical trials may not always be replicated in clinical practice. Real-world data comparing T&E and PRN regimens for nAMD are limited. The objective of this work was to report 24-month outcomes of PRN versus T&E regimens for ranibizumab and aflibercept to treat nAMD in routine clinical practice. We conducted a retrospective analysis of data from a prospectively designed observational outcomes registry, the Fight Retinal Blindness! Project (FRB). Treatment-naïve eyes starting nAMD treatment with at least three injections using a T&E or PRN regimen were tracked by using the FRB. The primary outcome was the mean change in visual acuity (VA) measured by the number of letters read on a logarithm of the minimum angle of resolution chart at 2years versus baseline. The secondary outcome was the number of injections at 2years. From January 1, 2015 to January 31, 2019, 3313 eyes from 2948 patients with nAMD were included: 1243 eyes from 1065 patients were classified as PRN and 2070 eyes from 1935 patients started a T&E regimen. At 24months, patients on the T&E regimen experienced significantly greater mean (95% confidence interval) improvement in VA than those on PRN (+ 4.2 [3.1, 5.2] vs. + 1.3 [0.1, 2.6] letters; p < 0.001), with more injections (14.9 standard deviation(SD) 4.3) vs. 9.8(SD 4.3); p < 0.001). Eyes treated with a T&E regimen had better VA outcomes from VEGF inhibitors than eyes treated PRN. This large real-world data assessment supports previous data from randomized clinical trials that the T&E regimen delivers better outcomes than PRN.

Natural History of Visual Acuity and Microperimetry-Based Functional Outcome Measures of the Macula in Patients with Geographic Atrophy: A Retrospective Chart Review Study in Germany.

Background/Objectives: Geographic atrophy (GA) is an advanced form of age-related macular degeneration (AMD) leading to the progressive and irreversible loss of visual function. Characteristics of GA include atrophic lesions resulting from the loss of photoreceptors, retinal pigment epithelium, and choriocapillaris. During GA progression, atrophic lesions typically advance from the macular periphery to the center, affecting foveal light sensitivity and visual acuity. This study analyzed changes in light sensitivity and visual acuity during the natural course of GA progression using the topographic analysis of structural and functional changes based on Early Treatment Diabetic Retinopathy Study (ETDRS) charts, multimodal imaging, and microperimetry assessment. Methods: Medical chart data of GA patients between 2014 and 2022 from the Internationale Innovative Ophthalmochirurgie GbR (I.I.O.) research center (Düsseldorf, Germany) were retrospectively analyzed. All patient eyes fulfilling the phase 3 OAKS study inclusion criteria were included and followed up for 60 months. The imputation of missing measurements and dropouts was performed by linear mixed models. Results: A total of 20 GA eyes from 13 GA patients were included in the study. At the index, 53.8% of patients had bilateral GA, with 70.0% of the eyes showing multifocal GA and 30.0% subfoveal encroachment (SFE). A total of 35.0% of the eyes had 2-5, and 15.0% over 20, areas of atrophy. Over time, the GA lesion size increased from 6.4 mm2 to 11.8 mm2 (1.08 mm2/year). After an average observation time of 2.9 years, 78.6% of the initially unaffected study eyes developed SFE. The percentage of study eyes without visual impairment decreased from 55.0% to 30.0%, with mean normal-luminance best-corrected visual acuity (NL-BCVA) reducing from 63.7 to 55.7 ETDRS letters. The share of absolute scotoma points in microperimetry assessment increased from 15.7% to 43.5% while overall average macular sensitivity declined from 15.7 dB to 7.4 dB. Conclusions: The substantial deterioration of macular outcomes and visual function was comprehensively detected. The results were a documentation of structural and functional aspects of the natural progression of GA for a 60-month follow-up, providing a typical outline for AMD patients with GA.

The effect of four loading intravitreal aflibercept injections on macular fluid in treatment-naïve neovascular age-related macular degeneration

PurposeTo evaluate the effect of four versus three loading aflibercept injections on macular fluid resolution and visual acuity (VA) in exudative neovascular AMD (nAMD).MethodsMulticentre, retrospective cohort study of treatment naïve nAMD eyes undergoing 3 versus 4 loading doses of aflibercept. Change in VA and fluid resolution on optical coherence tomography (OCT), were evaluated at 8 weeks post loading. The primary outcome was proportion of patients with no intraretinal (IRF) and/or subretinal (SRF) fluid at central 1 mm and whole macula at 8 weeks after loading. Data were summarised with mean ± SD for continuous variables, and n (%) for categorical variables.ResultsData from 995 patients was analysed (355 patients − 4 loading doses and 640–3 loading doses). At 8 weeks post 4 loading doses proportion of eyes with neither IRF nor SRF, no IRF and no SRF were 62.8%, 88.7% and 79.2% at fovea versus 56.1%, 87.9% and 69.9% in the whole macula, respectively. Fluid resolution at both fovea and macula were significantly higher in eyes with 4 loading injections versus 3 (p = 0.0001). The mean VA change was +4.0 (±11.3) and +5.4(±13.3) letters for 3 and 4 loading doses groups (p = 0.09).ConclusionFour loading dose injections of aflibercept results in higher proportion of eyes with total fluid resolution in the central subfield and total macular scan when compared to those receiving 3 loading dose injections at 8 weeks post loading phase. However, the better drying effect of 4th loading dose does not translate into better short-term VA outcomes.

Visual Outcomes and Risk of Endophthalmitis in Open Globe Injuries without Intraocular Foreign Bodies with Delayed Repair

To assess and compare the rate of endophthalmitis and visual outcomes in cases of OGI's without intraocular foreign bodies repaired within and greater than 24 hours from the time of injury. A retrospective review of 2,002 cases of OGI's presenting to a single institution. Patients with OGI's were admitted and managed according to a standardized protocol. The impact of timing of repair was assessed between those undergoing OGI repair within (i) 24 hours, (ii) 25-36 hours, and (iii) greater than 36 hours from the time of injury. Rates of endophthalmitis and postoperative visual acuity of logMAR 1.3, logMAR 1.0, and logMAR 0.3 at 180 days and 1 year following open globe repair. 1,382 patients with OGI's were included, of which 75% were male with an average age of 41 years. Maximal zone of injury was zone 1 for 468 patients, zone 2 for 529 patients and zone 3 for 508 patients. 84% of all OGI's underwent repair within 24 hours from the time of injury, 9% from 25-36 hours, and 7% greater than 36 hours. Average preoperative visual acuity was hand motion. Risk factors associated with repair performed greater than 36 hours from the time of injury included female sex (p=0.042). Endophthalmitis was associated with time to repair greater than 36 hours (p=0.049) but not with 25-36 hours or zone of injury (p=0.111). Time to repair had no significant impact on visual acuity outcomes. Although repair of OGI's within 24 hours is the current standard of care, this study found no statistically significant difference in rates of endophthalmitis or visual outcomes in eyes undergoing repair within 24 hours of injury compared to repair extending to 25 to 36 hours . Endophthalmitis rates did increase after 36 hours. We recommend urgent repair of open globe injuries, but in certain circumstances, it may be reasonable to delay repair beyond 24 hours to optimize operating conditions.

Outcomes of Corneal Compound Hyperopic Astigmatism With Presbyopia by Zeiss PRESBYOND Laser Blended Vision LASIK Using Default Custom Refractive Software Master Target Refractions for Reduced Anisometropia.

To evaluate the effectiveness, safety, and stability of a modified PRESBYOND Laser Blended Vision protocol (Carl Zeiss Meditec AG) for correcting hyperopic astigmatism and presbyopia, using Custom Refractive Software Master (CRSM) targeting over a 6-month period. A total of 636 eyes of 318 patients with a mean age of 51.05 ± 4.71 years (range: 40 to 60 years) met the inclusion and exclusion criteria. All patients completed a 6-month follow-up. CRSM software was used to generate ablation profiles for the MEL90 excimer laser (Carl Zeiss Meditec AG). The target refraction was emmetropic for the dominant eyes and between -0.75 and -1.12 diopters (D) for the near eyes. Visual and refractive results were studied separately by the dominant and non-dominant eyes. The mean attempt to correct for spherical equivalent refraction was +2.17 ± 1.16 D (range: -1.00 to +5.37 D). The mean attempted cylinder was -0.60 ± 0.75 D (range: -4.00 to 0.00 D). All eyes monocularly achieved uncorrected distance visual acuity (UDVA) of 20/25 or better after refractive treatment and 88% achieved 20/20. Binocularly all eyes achieved UDVA of 20/25 or better and 96.54% achieved 20/20. Ninety-eight percent of the patients maintained their corrected distance visual acuity before surgery and UDVA 6 months after surgery. This hyperopic micro-anisometropia protocol with PRESBYOND Laser Blended Vision was an effective, safe, and well-tolerated refractive treatment. It was an effective procedure with excellent results for UDVA and uncorrected near visual acuity and demonstrates that binocular summation exists. [ J Refract Surg. 2024;40(7):e480-e489.].

Long-term visual outcomes and fluid compartment changes in limited-early versus early response to anti-VEGF treatment for diabetic macular edema

ObjectiveThis study assessed best visual acuity (BVA) and central subfield thickness (CST) outcomes for LER (limited early responder) and ER (early responder) patients at 24 and 36 months. DesignRetrospective chart review ParticipantsOne-hundred and twelve patients characterized at 3 months after their first anti-VEGF injections as either LER if they met the anatomic criteria (aLER = CST reductions ≤ 10%), visual criteria (vLER = ETDRS letter gains < 5 letter), or both (cLER). All other patients were classified as ER (aER/vER/cER). MethodsVariables collected include CST and ETDRS letters at baseline, 3, 24, and 36 months following injections, comorbidities, smoking status, demographics, baseline systemic factors, and the type and quantity of anti-VEGF injections. Analyses were performed using Welch's t-test, multivariable linear and multivariable logistic regression. ResultsBVA changes from 3 months were significant between cLER versus cER and vLER versus vER groups (p < 0.05). There was a greater decrease in mean BVA from 3 months to 36 months in the cER group compared to the cLER group. Alternatively, mean BVA decreased in the vER cohort, while the vLER cohort slightly increased. CST changes from 3 months were statistically significant (p < 0.01) between all LER and ER groups with LER groups showing greater reductions compared to ER counterparts. BVA and CST changes from baseline to 24 and 36 months were not significant after controlling for baseline differences between LER and ER groups. ConclusionResults highlight the value of long-term anti-VEGF treatment and the need to further explore options that may lead to continued BVA improvements beyond 3 months.

Aphakia treatment with sutureless scleral fixation or retropupillary iris-claw intraocular lens implantation: visual acuity, anterior segment and keratometry outcomes

PurposeEvaluation of anterior segment parameters using the Scheimpflug corneal topography 1 year after surgery in patients who underwent sutureless scleral fixation intraocular lens (SFIOL) implantation using the modified Yamane technique and retropupillary iris-claw intraocular lens (RPIOL) implantation.MethodsA total of 60 eyes from 57 patients who underwent sutureless SFIOL implantation and 57 eyes from 52 patients who underwent RPIOL implantation were included. Anterior chamber depth (ACD), anterior chamber angle (ACA), anterior chamber volume (ACV), anterior–posterior corneal astigmatism, and keratometric values were assessed using the Scheimpflug corneal topography (Pentacam HR, Germany).ResultsThere was no statistically significant difference in postoperative UCVA and BCVA between the sutureless SFIOL and the RPIOL group (p = 0.236, p = 0.293, respectively). While there was no statistically significant difference in postoperative IOP between the two groups (p = 0.223), a statistically significant decrease in IOP was observed in both groups (p < 0.001). While there was no statistical difference between the sutureless SFIOL group and the RPIOL group in terms of spherical value (p = 0.441) and spherical equivalence (p = 0.237), there was a statistically significant difference in cylindrical value (p < 0.001). While there was a statistical difference in anterior astigmatism (p < 0.001), there was no statistical difference in posterior astigmatism (p = 0.405). There was no statistical difference in terms of ACV, ACD, and ACA between the sutureless SFIOL and the RPIOL group (p = 0.812, p = 0.770, p = 0.401, respectively).ConclusionIn this study, although there was a statistical difference in cylindrical value and anterior corneal astigmatism between the sutureless SFIOL and RPIOL groups, vision was not affected. According to this study, sutureless SFIOL and RPIOL are two successful methods in terms of visual acuity, anterior segment, and keratometry outcomes in aphakic patients after phacoemulsification.

Effect of Blue Light Filter Intraocular Lens (IOL) on Colour Vision.

Purpose The objective of this study is to knowthe effect of blue light filter (BF) intraocular lenses (IOL) on colour vision of Sudanese patiens as BF IOLs are relatively new in Sudan and its effect on Sudanese patients is not yet studied. Methods This was a descriptive cross-sectional observational study. Data collection was done through interview andpretested structured questionnaire containing three sections: (i) personal data, (ii) past medical and ocular surgical history, and (iii) visual acuity (VA), the anterior and posterior segment exam result, and the D15photopic color vision test result. Results In this study, 206 eyes of 103 patients were enrolled. Of them, 57 (55.3%) were females and 46 (44.7 %) were males. The mean age of the participants was 58.38 years±11.488 (SD). Furthermore, 81 patients (78.64%) achieved normal D15 color vision test results, while 22 patients (21.4%) had abnormal results. There was a significant effect (P=.00) on photopic color vision perception. Finally, the gender-wise performance showed an insignificant difference (P=.933)with 78.3% of the males having normal D15 color vision test and the females having slightly better results with 78.9 %. Conclusions The results suggested that implantation of BF IOLs has a significanteffect on photopic color vision perception.

Correlation of limited-early-response status with 12-month CST, BVA, and machine learning-quantified retinal fluid in diabetic macular oedema in routine clinical practice

Background/ObjectivesAnti-VEGF treatment response in DMO has been measured by changes in the central subfield thickness (CST) and best visual acuity (BVA) outcomes at 3 months after initial treatment, termed early or limited early response (ER/LER). This study correlates LER with 12-month BVA, CST, and retinal fluid volumes quantified by a machine learning algorithm on optical coherence tomography (OCT).Subjects/MethodsThe study included treatment naïve DMO patients ≥ 18 years with OCT scans at baseline (M0), M3, M6, and M12. The 220 patients were categorized as limited early responders (LER) if they had ≤ 10% CST reduction and/or < 5 ETDRS letter gain at M3. BVA, CST, and subretinal (SRF), intraretinal (IRF), and total retinal (TRF) fluid volumes quantified by a machine learning algorithm were compared between groups and across time.ResultsAt M12, the anatomic LER (aLER), defined solely by CST, had significantly worse BVA and CST versus the anatomic ER (aER) group (p < 0.001). Retinal fluid M12 outcomes did not significantly vary between all LER and ER groups. No significant BVA, CST, TRF, and IRF variance across time for LER was found (p > 0.1).ConclusionsBVA and CST M12 outcomes vary by aLER/aER status indicating that CST may be a strong predictor of treatment outcomes, while retinal fluid volumes were not predicted by LER status.

An Effective Treatment for Progressive Keratoconus with Two-Year Outcomes: Accelerated Epithelium-on Corneal Cross-Linking

Purpose: Corneal collagen cross-linking is a surgical technique for progressive keratoconus. There are several technical modifications with varying clinical outcomes. This study aimed to evaluate the long-term outcomes of the accelerated epithelium-on collagen cross-linking. Design &amp; Methods: A retrospective study was performed on progressive keratoconus patients treated via the accelerated epithelium-on collagen cross-linking who completed the 24th-month follow-up. We included 111 eyes of 77 patients. Clinical variables, including visual acuity, aberrometry, topographic measurements, and refractive outcomes, were evaluated at the postoperative 12th and 24th months. Results: There was a significant improvement in postoperative visual acuity in 50.4% of the patients (p

Retrospective Large Database Study of Central Serous Chorioretinopathy Treatments and Visual Outcomes Analysis in the United States.

Purpose: To evaluate a large database detailing the changes in visual acuity (VA) and central subfield thickness after various treatments for central serous chorioretinopathy (CSCR). Methods: A retrospective analysis was performed of patients with CSCR from January 2015 to September 2022 using the Vestrum Health Retina Database of aggregated de-identified electronic medical records from retina specialists in the United States. The cases of CSCR were categorized by age, sex, and treatment provided. Results: The annual incidence of CSCR was 1.72% (61 755 of 3 598 672 patient eyes), with a mean patient age of 53 years. Male eyes comprised 71.8% of the patient population. Eighty-five percent of patients received no treatment within 1 year of diagnosis. Of the patients needing treatment, 21% received thermal laser therapy, 23% photodynamic therapy, and 49% antivascular endothelial growth factor (anti-VEGF) intraocular injection. Patients not receiving treatment had the best baseline and 1-year VA. All treatment groups had an increased percentage of patients gaining letters compared with patients not receiving treatment. Conclusions: Although most patients did not require treatment, those who received treatment generally did well, with a large proportion having visual gain. Statistical analysis suggests treatment has a positive impact on VA outcomes. Patients receiving combination treatment were older and had the least visual gain of the treated cohorts. Younger patients with CSCR treated with anti-VEGF (and without a secondary diagnosis of macular degeneration) had the greatest increase in VA at 1 year.

A retrospective analysis of the management and surgical treatment of orbital lesions: Outcomes and rationale

The orbital cavity is a subject of interest for various specialists, and achieving optimal outcomes requires comprehensive, multidisciplinary management. This study aims to report 10 years of experience in the preoperative, surgical, and postoperative care of patients with orbital lesions, examining their clinical, radiological, and anatomopathological features and outcomes.A retrospective review of 125 patients who underwent surgical treatment for intraorbital masses between January 2012 and December 2021 was performed. Outcome measures included postoperative diplopia, exophthalmos, decimal visual acuity, eyeball position, ocular motility, operative time, complications, and aesthetic results. A total of 107 patients were included. All cases were discussed with a neuroradiologist to determine the best therapeutic approach based on preoperative imaging.Preoperative diplopia was linked to extraconal (p = 0.03) and anterior (p = 0.001) lesions, and exophthalmos and visual acuity deterioration were associated with intraconal (p = 0.02; p = 0.03) and retrobulbar (p = 0.001; p = 0.02) lesions. Complications (11.2%) included diplopia, worsened visual acuity, postoperative blepharoptosis, and postoperative ectropion. Of the patients, 80.4% reported an "excellent" aesthetic outcome.This study underscores the importance of a multidisciplinary approach based on a thorough analysis of preoperative imaging. Periorbital approaches tailored to the lesion's three-dimensional location enables safe access to most intraorbital lesions, resulting in minimal complications and good aesthetic results.

Long-Term Clinical Course and Treatment Outcomes in Occult and Overt Acute Zonal Outer Retinopathy

ABSTRACT Purpose To report the longitudinal outcomes for AZOOR patients including treatment response, imaging evolution, and overlap with multiple evanescent white dot syndrome (MEWDS). Methods Visual acuity (VA) and visual field (VF) outcomes of occult and overt AZOOR patients were retrospectively compared between the first and final visits as well as between the two AZOOR subtypes. For treated patients, rates of VA change and fundus lesion area were compared before and after treatment. Analyses were performed using STATA 17. Results Seventeen eyes from 11 occult AZOOR patients and 45 eyes from 29 overt AZOOR patients were included. In a composite VA/VF primary outcome, clinical improvement was noted in five occult AZOOR and three overt AZOOR patients. The decline of logarithm of the Minimal Angle of Resolution (logMAR) VA was minimal in both groups: 0.00016 units/month in occult AZOOR patients and 0.009 units/month in overt AZOOR patients (p = 0.94). Occult AZOOR patients were more likely to have improved or stable VF than overt AZOOR patients (p = 0.04). One occult AZOOR and two overt AZOOR patients developed MEWDS at subsequent visits. Treatment with steroids or immunomodulatory therapy (IMT) was initiated in one occult AZOOR patient and nine overt AZOOR patients. Treated patients had overall VA stability. Fundus lesion area in treated patients changed by a mean of 0.2831 mm2/month, with 40% of patients showing decreased lesion area. Conclusion AZOOR patients generally maintained their VA. Overt AZOOR patients were more likely to receive steroids or IMT; treatment was associated with stabilization of VA.

Clinical characteristics, visual acuity outcomes, and factors associated with loss of vision among patients with active ocular toxoplasmosis: A retrospective study in a Thai tertiary center.

Ocular toxoplasmosis (OT) is the most common cause of infectious uveitis worldwide, including Thailand. This study describes the clinical presentation, visual acuity (VA) outcomes, and factors associated with VA loss in patients with active OT following antiparasitic treatment. A retrospective chart review of patients with active OT treated with antiparasitic drugs between 2010 and 2020 was performed. Outcome measures included clinical characteristics, interval VA, and predictive factors associated with loss of VA ≤ 20/50 at 6 months post-treatment. Ninety-two patients (95 eyes) were enrolled. The median follow-up time was 10.9 months (IQR 4.9-31.8 months). The median age at presentation was 35.9 years, 51% were male, and 92.4% had unilateral OT. Eleven patients (12%) were immunocompromised (HIV infection, eight patients; receiving immunosuppressive agents, three patients). Patients mainly presented with primary retinitis without previous scar (62%), posterior pole lesion (56%), and lesion size of ≤ 2-disc area (75%). Immunocompromised patients showed a significantly larger size of retinitis than immunocompetent patients. Oral trimethoprim/sulfamethoxazole monotherapy was the primary short-term antiparasitic drug prescribed (85%). At the final visit, 21% of all affected eyes suffered VA ≤ 20/200. The cumulative incidence of recurrent OT at three years was 33.9% (95% CI, 19.7%-54.2%). Immunocompromised patients [adjusted odds ratio (aOR) 4.9, p = 0.041], macular lesion (aOR 5.4, p = 0.032), and initial VA ≤ 20/200 (aOR 9.1, p = 0.014) were predictive of having VA ≤ 20/50 at 6 months post-treatment. Ocular toxoplasmosis mainly presents as unilateral primary retinitis within the posterior pole. Severe VA loss was observed in one-fifth of eyes following treatment with lesion resolution. Immunocompromised patients, eyes with macular lesions, and poor initial VA were associated with poor VA outcomes.
