Intravitreal anti-vascular endothelial growth factor (VEGF) injections are commonly used to treat eyes with macular edema secondary to hemiretinal vein occlusion (HRVO) or central retinal vein occlusion (CRVO). Information on whether differences exist in outcomes after anti-VEGF therapy can help guide treatment for each of the different disease types.To compare baseline characteristics, treatment burden, and outcomes of macular edema treatment in participants with HRVO with those of participants with CRVO.This post hoc outcome analysis from the Study of Comparative Treatments for Retinal Vein Occlusion 2 randomized clinical trial included 362 participants with macular edema caused by HRVO or CRVO treated at 66 US sites. Randomization began in September 2014, and the last month 24 follow-up visit occurred in February 2018. Data were analyzed from April 2020 to May 2021.Eyes were initially randomized to 6 monthly intravitreal injections of aflibercept or bevacizumab and were treated according to protocol between months 6 to 12 depending on 6-month outcome. After month 12, patients were treated per investigator discretion and observed through month 60.Mean visual acuity letter score (VALS).Of 362 included patients, 157 (43.4%) were female, and the mean (SD) age was 68.9 (12.0) years. Outcome data were analyzed up to month 24 owing to substantial missing data at later visits. A significantly greater proportion of participants with HRVO than those with CRVO were Black (37% vs 11%). Treatment rates between months 12 to 23 were 0.36 (95% CI, 0.32-0.40) injections per month for patients with CRVO and 0.28 (95% CI, 0.19-0.36) for patients with HRVO (P = .11). The mean VALS from months 1 to 24 of an HRVO study eye exceeded that of a CRVO study eye by 5.5 (95% CI, 1.5-9.5; P = .01), consistent with the magnitude of the VALS difference between eyes with CRVO and HRVO at baseline. Eyes with CRVO presented at baseline with more macular edema than eyes with HRVO (difference in central subfield thickness [CST], 86 μm; 95% CI, 48-124; P < .001), with no difference in CST between the groups throughout months 1 to 24.Black race was more prevalent among participants with HRVO than CRVO, and no differences were observed in the frequency of treatments for macular edema between eyes with CRVO and HRVO. Although eyes with CRVO presented with worse visual acuity and more macular edema on average than did eyes with HRVO, the magnitude of VALS improvement, central retinal thickness in response to anti-VEGF therapy, and treatment burden were similar between the groups.
To assess the efficacy of a treat-and-extend strategy with intravitreal ranibizumab for radiation-related macular edema. Forty eyes with radiation-induced macular edema and decreased visual acuity were enrolled in the phase IIb, prospective clinical trial and randomized into 3 cohorts: (A) monthly ranibizumab, (B) monthly ranibizumab with targeted retinal photocoagulation (TRP), or (C) as-needed ranibizumab and TRP. In year 2, all subjects entered a treat-and-extend protocol for ranibizumab. The primary outcome measure was mean change in early treatment diabetic retinopathy study (ETDRS) best-corrected visual acuity (BCVA) from baseline. Through year 1, the mean change in ETDRS BCVA was significantly different between the three cohorts (p < 0.001); cohort A saw the largest gain with + 4.0 letters. Significant anatomic improvements were also seen in all cohorts. Comparatively, through year 2, cohorts A, B, and C had a mean change in ETDRS BCVA of − 1.9, − 3.9, and + 1.3 letters, respectively; additionally, no significant differences were found in absolute ETDRS BCVA across time (ANOVA, p = 0.123). Overall, 90% of eyes maintained VA 20/200 or better and 33.3% of subjects gained at least one line of vision. There were no significant differences in mean central macular thickness for any cohort compared to baseline (p = 0.09). The presence of retinal hemorrhage and intraretinal exudates stayed consistent from year 1 to year 2 for all cohorts. Among eyes with radiation-related macular edema, a treat-and-extend regimen with ranibizumab may not result in as many visual and anatomic improvements as monthly injections. However, treat-and-extend still may prevent serious visual complications compared to historical controls. ClinicalTrials.gov Identifier: NCT02222610
PURPOSE: To assess efficacy of intravitreal ranibizumab injections and targeted panretinal photocoagulation (TRP) for radiation retinopathy-related macular edema. DESIGN: Phase IIb, prospective, randomized clinical trial. METHODS: SETTING: Multicenter. SUBJECTS: Forty eyes in 40 treatment-naive patients with radiation-induced macular edema and a resulting decrease in visual acuity ranging between 20/25 and 20/400 (Snellen equivalent). INTERVENTION: Patients either received intravitreal 0.5 mg ranibizumab monthly, monthly ranibizumab with TRP, or 3 monthly ranibizumab (loading doses) followed by as-needed (PRN) injections and TRP. After week 52, all subjects entered a treat-and-extend protocol for ranibizumab. MAIN OUTCOME MEASURES: Mean Early Treatment Diabetic Maculopathy Study (ETDRS) BCVA change from baseline. RESULTS: Mean patient age was 57 years (range, 22-80 years), ETDRS BCVA was 56.7 letters (20/74 Snellen equivalent), and central macular thickness (CMT) was 423 mu m (range, 183-826 mu m). Thirty-seven patients completed the month 12 visit (92.5%), at which time the change in mean BCVA was + 4.0 letters, - 1.9 letters, and + 0.9 letters in the monthly, monthly plus laser, and PRN plus laser cohorts, respectively. There was a significant difference in mean BCVA at 1 year among all 3 cohorts (P < .001), as well as between cohorts in pairwise comparisons, with the most significant gains in the monthly group. A total of 82.5% of the patients retained visual acuity of 20/200 or better, and 20.0% improved 10 or more ETDRS letters. CONCLUSIONS: Ranibizumab may improve vision and anatomy in patients with radiation retinopathy-related macular edema and prevent vision loss through 48 weeks of therapy. Monthly injections were more effective than as-needed approach, and the addition of TRP yielded no therapeutic benefits. (C) 2020 Elsevier Inc. All rights reserved.
ImportanceTwo-year outcomes are reported comparing eyes originally assigned to aflibercept or bevacizumab to assess the need for continued anti-vascular endothelial growth factor (VEGF) therapy for macular edema due to central retinal vein occlusion (CRVO) or hemiretinal vein occlusion (HRVO) from participants in the Study of Comparative Treatments for Retinal Vein Occlusion 2 (SCORE2) trial.ObjectiveTo investigate outcomes 1 year after cessation of the SCORE2 treatment schedule.Design, Setting, and ParticipantsIn this secondary analysis of the SCORE2 randomized clinical trial, follow-up included 117 participants originally randomized to aflibercept and 119 participants originally randomized to bevacizumab between September 17, 2014, and November 18, 2015. Data for the analyses were frozen on September 13, 2018.InterventionsSCORE2 participants completed the treatment protocol at month 12, were subsequently treated at investigator discretion, and underwent assessment at month 24.Main Outcomes and MeasuresVisual acuity letter score (VALS) and central subfield thickness (CST) on spectral-domain optical coherence tomography.ResultsAmong 362 participants randomized to aflibercept or bevacizumab, 65.2% (236 of 362) completed a protocol visit at month 24 (mean [SD] age, 68.5 (12.0) years; 53.8% male). The mean (SD) VALS improved from baseline to 12 months by 21.6 (14.5) in the aflibercept group compared with 21.9 (16.6) in the bevacizumab group (difference, -0.3; 99% CI, -5.6 to 4.9), then worsened from those values by a mean (SD) VALS of 7.6 (17.5) in the aflibercept group and 7.5 (14.5) in the bevacizumab group (difference, -0.1; 99% CI, -5.6 to 5.3) at month 24. The mean (SD) CST improved from baseline to 12 months by 394 (231) μm in the aflibercept group compared with 420 (274) μm in the bevacizumab group (difference, 26 μm; 99% CI, -62 to 114 μm), then worsened from those values by a mean (SD) of 58 (192) μm in the aflibercept group compared with 48 (186) μm in the bevacizumab group (difference, 10 μm; 99% CI, -58 to 78 μm) at month 24.Conclusions and RelevanceNo differences in VALS or CST outcomes at month 24 were identified when participants originally assigned to aflibercept were compared with those assigned to bevacizumab. Caution in interpretation is needed because of loss to follow-up. In both groups, VALS and CST improved through month 12 and then worsened somewhat during the second year, when treatment was at investigator discretion. This analysis suggests that CRVO and HRVO warrant close monitoring and treatment as needed over at least 2 years to optimize outcomes in eyes treated with anti-VEGF therapy.Trial RegistrationClinicalTrials.gov identifier: NCT01969708.
Importance Recent reports suggest that cilioretinal arteries (CRAs) confer protection against developing advanced age-related macular degeneration (AMD). Objective To further characterize the association between the presence of a CRA and incidence of geographic atrophy (GA) or choroidal neovascularization (CNV). Design This cohort study constituted an ad hoc secondary analysis of data from the Comparison of Age-Related Macular Degeneration Treatments Trials (CATT) and was performed at 44 clinical centers in the United States among participants in CATT with CNV in the study eye and without advanced AMD in the fellow eye at baseline. The presence of a CRA was determined by 2 graders, masked to clinical data, using color fundus photographs, red-free fundus photographs, and fluorescein angiography. The proportion with CRAs at baseline between the study eye with CNV and fellow eye without CNV was first compared. The association of a CRA with incidence of CNV or GA at 5 years among fellow eyes and with incidence of GA among study (treated) eyes was then assessed. In addition, the association of CRAs with the Age-Related Eye Disease Study severity scale among the fellow eyes at baseline was assessed. Data were collected from February 1, 2008, through April 30, 2015, and analyzed from July 1, 2018, through April 30, 2019. Exposures Presence of a CRA. Main Outcomes and Measures The association between the presence of a CRA and incidence of CNV or GA at 5 years of follow-up. Results A total of 350 patients (700 eyes) (230 [65.7% women; mean [SD] age, 77 [7.2] years) were included in the analysis. Cilioretinal arteries were present in 67 of 345 (19.4%) fellow eyes without baseline CNV and 73 of 349 (20.9%) study eyes with baseline CNV (P = .60). Cilioretinal arteries in fellow eyes were not associated with incidence of CNV at 5 years (125 of 278 [45.0%] among eyes without CRAs and 30 of 67 [44.8%] among eyes with CRAs; P = .99) or with incidence of GA at 5 years (110 of 278 [39.6%] among eyes without CRAs and 25 of 67 [37.3%] among eyes with CRAs; P = .89). Cilioretinal arteries in study eyes were not associated with incidence of GA at 5 years (105 of 276 [38.0%] study eyes without CRAs and 26 of 73 [35.6%] study eyes with CRAs; P = .72). Conclusions and Relevance The analysis did not find a protective association between CRAs and incidence of CNV or GA among CATT participants who had unilateral exudative AMD. Why these findings were different from those of previous publications is unclear but may be partially explained by the different techniques used to detect CRAs or by the baseline advanced disease in CATT participants.

Purpose: To compare the efficacy of iodine-125 (I-125) and ruthenium-106 (Ru-106) episcleral plaque radiation therapy and proton beam radiation therapy (PBRT) in the treatment of choroidal melanoma.Design: A retrospective, nonrandomized comparative study.Methods: Charts of patients treated with I-125, Ru-106, and PERT for choroidal melanoma between January 1988 and June 1996 at St. Bartholomew's Hospital and Moorfields Eye Hospitals were reviewed.Main Outcome Measure: Local control of choroidal melanomas after I-125,Ru-106, Or PERT.Results: A total of 597 patients were identified (I-125 = 190, Ru-106 = 140, PERT = 267). Patients treated with Ru-106 had a significantly greater risk of local tumor recurrence than did patients treated with either I-125 (P = 0.0133; confidence interval [CI], 1.26-7.02; risk ratio, 2.97) or PERT (P = 0.0097; CI, 1.30-6.66; risk ratio, 2.94). A stepwise Cox proportional hazard model found maximal basal diameter to be a significant covariate (P = 0.0033).Conclusion: Patients treated with Ru-106 had a significantly greater risk of local tumor recurrence than did those patients treated with either I-125 or PBRT.
This article presents a detailed, retrospective analysis of 597 choroidal melanoma eyes treated with radiation therapy in England. The authors have the stated goal of comparing the efficacy of iodine-125 (125I) episcleral plaque therapy, ruthenium-106 (106Ru) episcleral plaque therapy, and proton beam radiation therapy. Radiation outcome was measured by local tumor control. The conclusion of the authors is that their patients treated with ruthenium plaques had a significantly greater risk of local tumor recurrence than did patients treated with iodine plaques. There was no statistically significant difference in the recurrence rate when comparing ruthenium to proton beam or iodine to proton beam.
A group of eyes with clear media and diabetic traction retinal detachments treated with vitreous surgery were statistically analyzed to identify those parameters that would allow us to improve case selection. The configuration of the retinal detachment proved to be important, with hammock and flat diffuse central detachments having a good prognosis, and highly elevated, atrophic detachments such as table-top and tent-shaped demonstrating a poor prognosis. Eyes with florid diabetic retinopathy did less well than those with more inactive forms of retinopathy. Preretinal membranectomy, although accompanied by an increased rate of iatrogenic retinal tears, has a definite role in the treatment of more complex traction detachments and increases the number of eyes that may benefit from surgery. Eyes with preoperative vision better than 5/200 did significantly better than eyes with poorer preoperative vision.
A review of over 1,000 cataract operations performed over a two year period resulted in an approximately balanced indication for spectacles, daily wear contact lenses, and intraocular lenses.However, following 3% of the cataract procedures, an extended wear lens was required.The reasons for this selective need for extended wear, when other modalities for visual rehabilitation are available, is discussed.The practical importance of a limited but necessary use of extended wear lenses is reviewed.
