Abstract
PURPOSE: To report preoperative prognostic factors associated with visual acuity recovery 1 year after combined cataract and idiopathic epiretinal membrane (ERM) surgery and to introduce a predictive score. DESIGN: Interventional case series and estimation of a predictive score. METHODS: One hundred forty-two patients (1 eye per patient) operated on for combined cataract and idiopathic ERM in the University Hospital of Dijon were followed for 12 months. Preoperative clinical features and spectral-domain optical coherence tomography (OCT) parameters were compared between eyes that recovered ≥20/20 final best-corrected visual acuity (BCVA) and those with <20/20 final BCVA. Multivariate analysis and predictive score were provided. RESULTS: At 12 months, 60 eyes (42%) recovered ≥20/20 BCVA and 82 (58%) had lower visual results. Logistic regression analysis showed that final BCVA was associated with age (P = .040), duration of symptoms (P = .025), initial BCVA (P = .002), and inner and outer segment (IS/OS) junction disruption on spectral-domain OCT (P = .010). The preoperative 10-point predictive score including these parameters reached 82% sensitivity and 66% specificity. With a score >5, patients had a ≥56% chance of recovering 20/20 final BCVA instead of ≤27% when the score was ≤5. CONCLUSIONS: Age, duration of symptoms, and initial BCVA appear to be reliable prognostic factors in patients undergoing combined cataract and idiopathic ERM surgery. Combining these factors with analysis of the IS/OS junction provides a predictive score to estimate individual chances of good visual outcome.
