PURPOSE: To describe the clinical course, visual outcome, and prognosis of isolated, idiopathic retinal vasculitis. METHODS: Eighty patients (150 eyes) with isolated, idiopathic retinal vasculitis were included. Demographic data, clinical data, complications at the initial visit and during follow-up, fluorescein angiography, and optical coherence tomography findings were collected from the Massachusetts Eye Research and Surgery Institution (MERSI) database from September 2005 to February 2015. RESULTS: Seventy-five (93.7%) patients required treatment with immunomodulatory therapy. Of those 75 patients, 60 (75%) patients were able to achieve durable remission. Factors which were independently significant predictive of poor visual outcome were lower initial visual acuity (OR: 3.78; 95% CI: 1.75-8.16; P = 0.001), cystoid macular edema (OR: 5.54; 95% CI: 1.81-16.99; P = 0.003), and macular ischemia (OR: 5.12; 95% CI: 1.12-23.04; P = 0.036). CONCLUSION: The majority (67.25%) of our patients enjoyed a good visual outcome (most recent visit best-corrected visual acuity equal to or better than 20/40 and within one line or better from the baseline) with immunomodulatory therapy. We found that cystoid macular edema, macular ischemia, and lower best-corrected visual acuity during the first consultation visit were significant independent risk factors for poor visual outcome.
