Optical coherence tomography-guided ranibizumab injection for cystoid macular edema in well-controlled uveitis: twelve-month outcomes.


PMID 25170857

Abstract

To determine whether serial ranibizumab injections are effective in the treatment of cystoid macular edema in patients with chronic controlled noninfectious uveitis. Five eyes of 5 patients were included in a prospective noncomparative therapeutic trial. They received intravitreal injections of ranibizumab at Day 0 and were followed monthly for 1 year. Injections were repeated monthly if persistent or new cystic edema manifested on optical coherence tomography. The primary outcome measure was the mean change in best-corrected visual acuity from baseline at 12 months. Secondary outcome measures included mean percentage change in central subfield retinal thickness (CST) and incidence of adverse events through Month 24. Thirty-two injections were performed over the study period. At 1 year, the mean increase in acuity was 12.2 Early Treatment for Diabetic Retinopathy Study letters (P = 0.015). There was a statistically significant increase in visual acuity over time (P = 0.002). The CST decreased by 31.4%, 46.0%, 37.6%, and 45.4% relative to baseline at 3, 6, 9, and 12 months, respectively (P = 0.003). One patient experienced recurrence of uveitis with subsequent cataract and glaucoma progression. Optical coherence tomography-guided monthly intravitreal ranibizumab injections delivered over the course of 1 year resulted in improved vision and reduced central retinal thickness.
