Abstract
AbstractBackgroundEpiretinal membrane (ERM) is a common finding in patients with uveitis that contributes to visual impairment. We describe the long‐term visual acuity (VA) and morphometric progression in patients with uveitis and epiretinal membrane (ERM).MethodsRetrospective cohort study of patients with uveitic ERM from a tertiary centre database. Multivariate analysis of risk factors for ERM progression was calculated using a marginal Cox regression model to estimate hazard ratios (HR).ResultsTwo hundred and sixteen eyes (4%) of a total 5450 eyes with uveitis were identified to have an ERM. The most common diagnosis was idiopathic uveitis in 45 patients (28.7%), followed by sarcoidosis in 21 (13.4%), HLAB27‐related uveitis in 15 (9.6%) and toxoplasmosis in 15 (9.6%). Risk factors for ERM development include age (HR 1.03), intermediate uveitis (HR 2.33), posterior uveitis (HR 1.53) and ERM fellow eye (HR 18.28). Anterior uveitis (HR 0.53) and alternating disease (HR 0.53) were protective. Median VA was 20/40 at diagnosis of ERM and 20/40 at final follow up. Progression of ERM grade occurred in 17 eyes (7.9%) during the study period. ERM peel was performed in 44 eyes (20.4%). Median VA was 20/60 and 20/40 at baseline and 12 months after surgery, respectively. Improvement in visual acuity occurred in 23 eyes (60.5%) following surgery.ConclusionsIn addition to intermediate and posterior uveitis, fellow eye involvement is a strong risk factor for ERM development. In treated uveitis, the majority maintain their long‐term vision and rates of ERM progression are low.
