Abstract
PURPOSE: To evaluate clinical features and long-term visual outcome of cytomegalovirus (CMV) retinitis in patients without human immunodeficiency virus (HIV) infection, and to determine factors that predict visual outcome. DESIGN: Retrospective cohort study. METHODS: Consecutive patients with CMV retinitis without HIV infection were reviewed. Main outcome measures included clinical features, proportion of eyes with 6-month and final visual acuity (VA) <20/70 and <20/400, and odds ratios of factors associated with poor visual outcome. RESULTS: A total of 20 eyes from 13 patients were included with a median follow-up time of 17 months. All had at least 6 months of follow-up except 1 patient who died from sepsis at 1 month. At presentation, 50% of eyes had VA <20/70 and 25% had VA <20/400. Zone 1 involvement occurred in 55% and vitreous haze ≥grade 2+ occurred in 25%. Recurrence occurred in 33.3% at a mean time of 6.4 ± 3.3 weeks after discontinuation of anti-CMV therapy. The retinal detachment rate was 21.7% per eye-year and mortality rate was 11.7% per person-year. At final visit, 60% had VA <20/70 and 35% had VA <20/400. Macular involvement was significantly associated with poor final VA <20/400 (odds ratio = 25.00, P = .016). CONCLUSIONS: CMV retinitis without HIV infection was often aggressive at presentation. Significant intraocular inflammation was not uncommon. The long-term visual outcome was poor, especially in those with macular involvement.
