PURPOSE: To study the prognostic factors that influence best-corrected visual acuity (BCVA) outcome in patients with secondary epiretinal membrane (ERM) after retinal detachment surgery. DESIGN: Retrospective case series. METHODS: Forty-two patients with ERM were divided into macula-on and macula-off groups based on the macular status before retinal detachment surgery and were studied using the same spectral-domain optical coherence tomography device. Several variables, including the integrity of the external limiting membrane (ELM), the status of the photoreceptor inner segment/outer segment (IS/OS) junction line, and central foveal thickness were evaluated in 17 treated and 25 untreated patients. Linear regression analysis was used to determine the best combination of all variables affecting BCVA. RESULTS: Final BCVA was significantly better in macula-on and macula-off eyes with intact ELMs and IS/OS junction lines (0.35 ± 0.18 logarithm of the minimal angle of resolution [logMAR] and 0.51 ± 0.17 logMAR, respectively) than in macula-off eyes with disrupted or absent ELMs and IS/OS junction lines (0.83 ± 0.17 logMAR and 1.04 ± 0.05 logMAR, respectively; P < .001, analysis of variance). Final BCVA also was better in the treated group than in the controls (0.55 ± 0.31 logMAR and 0.73 ± 0.26 logMAR, respectively; P = .05, t test). ELM and IS/OS junction line integrity were the main variables significantly affecting the final BCVA outcome (β = 0.42; P = .006, linear regression analysis). Disruption of the ELM and IS/OS junction line was observed in 21 of the 42 cases studied. CONCLUSIONS: ERM secondary to retinal detachment surgery is accompanied by a high incidence (50%) of IS/OS junction line and ELM disruption. Among the variables studied, the condition of the IS/OS junction layer and the ELM are the main factors that predict final BCVA after ERM peeling.
