Baseline characteristics and response to treatment of participants with hemiretinal compared with branch retinal or central retinal vein occlusion in the standard care vs corticosteroid for retinal vein occlusion (SCORE) study: SCORE study report 14.

ABSTRACT: OBJECTIVE:To compare baseline characteristics and treatment response of participants with hemiretinal vein occlusion (HRVO) with those of participants with branch retinal vein occlusion (BRVO) or central retinal vein occlusion (CRVO) in the Standard Care vs COrticosteroid for REtinal Vein Occlusion (SCORE) Study. METHODS:Eyes were randomized to standard care, 1 mg intravitreal triamcinolone acetonide, or 4 mg intravitreal triamcinolone acetonide. Standard care was observation in the SCORE-CRVO trial and grid photocoagulation in the SCORE-BRVO trial. The HRVO eyes were enrolled in the SCORE-BRVO trial. Baseline characteristics, changes in visual acuity and center point thickness, safety outcomes, and number of treatments were compared among HRVO, BRVO, and CRVO participants. RESULTS:At baseline, HRVO eyes were intermediate between BRVO and CRVO eyes in area of retinal thickening, area of fluorescein leakage, visual acuity, and center point thickness. No differences in visual acuity change from baseline to 1 year were noted between standard care groups for HRVO and BRVO. Within triamcinolone-treated eyes, HRVO eyes did not differ from BRVO eyes in visual acuity change, but HRVO eyes fared better than CRVO eyes. There were no differences in center point thickness change between standard care groups for HRVO and BRVO, nor were there differences across the 3 disease entities for triamcinolone-treated eyes. There were no differences in frequency of protocol treatments and adverse events. CONCLUSIONS:The HRVO participants were similar to BRVO and CRVO participants regarding most demographic characteristics, with fundus findings intermediate between BRVO and CRVO. In the SCORE Study, HRVO was treated as BRVO; HRVO eyes responded to treatment similarly to BRVO eyes, and there was no difference among the 3 disease entities in frequency of protocol treatments and adverse events.

Project description:ImportanceMacular edema (ME) is the leading cause of decreased visual acuity (VA) associated with retinal vein occlusion (RVO). Identifying factors associated with better outcomes in RVO eyes treated with anti-vascular endothelial growth factor (VEGF) therapy may provide information useful in counseling patients.ObjectiveTo investigate baseline characteristics associated with 6-month VA and central subfield thickness (CST) outcomes in participants in the Study of Comparative Treatments for Retinal Vein Occlusion 2 (SCORE2).Design, setting, and participantsA total of 362 patients with central RVO or hemi-RVO were enrolled between September 17, 2014, and November 18, 2015, and randomized 1:1 in a masked fashion to receive bevacizumab or aflibercept. At month 6, 348 participants (96%) had VA outcomes measured and 335 participants (93%) had spectral domain optical coherence tomography outcomes measured. The current data analysis was conducted from February 27, 2017, to April 7, 2017.InterventionsEyes were randomly assigned to receive an intravitreal injection of bevacizumab, 1.25 mg, or aflibercept, 2.0 mg, at baseline and every 4 weeks, with the primary outcome measured at 6 months.Main outcomes and measuresChange from baseline in VA letter score (VALS), VALS gain of 15 or more, change from baseline in CST, CST less than 300 µm, and resolution of ME. Baseline factors associated with 6-month outcome at the 0.05 level in univariate regressions were included in multivariate regressions, with those significant after multiplicity control by the Hochberg method reported.ResultsThe mean (SD) age of patients was 69 (12) years, and 43% were women. Younger patient age (odds ratio [OR], 0.95 per year of age; 95% CI, 0.93-0.98; P = .007) and lower baseline VALS (OR, 0.96 per letter; 95% CI, 0.94-0.98; P < .001) were associated with a 6-month VALS gain of 15 or greater. Compared with bevacizumab, aflibercept treatment was associated with a higher odds of ME resolution (OR, 3.59; 95% CI, 2.22-5.80; P < .001) and CST less than 300 µm (OR, 5.30; 95% CI, 2.40-11.67; P = .001), but not with a better VA outcome. Macular edema was less likely to resolve in eyes that received anti-VEGF treatment prior to study participation (OR, 0.33; 95% CI, 0.17-0.64; P = .03).Conclusions and relevanceIn eyes treated with bevacizumab or aflibercept, younger age and worse baseline VALS were associated with better 6-month VA outcomes. Aflibercept treatment was associated with more favorable spectral domain optical coherence tomography outcomes but not VA outcomes. These findings may be useful in assessing expected response at month 6 after monthly injection of anti-VEGF agents for treating ME due to CRVO and HRVO.Trial registrationclinicaltrials.gov Identifier: NCT01969708.
