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.

BACKGROUND: To evaluate the correlations between anatomical and functional changes studied with microperimetry (MPM) and spectral-domain OCT (SD-OCT) in patients after successful repair of idiopathic macular hole (MH). METHODS: Monocentric, retrospective, interventional study in 23 eyes of 23 patients who underwent successful surgery for MH defined as closure of the hole, at least 1 year before. Reported data were pre- and postoperative best-corrected visual acuity (BCVA), retinal sensitivity values on MPM, macular and foveal thicknesses, and retinal anatomic lesions on SD-OCT. RESULTS: Macular sensitivity (MS) and foveal sensitivity (FS) were lower and the number of lesions of the outer retinal layers was higher in patients with a poorer postoperative VA (P = 0.029, P = 0.011 and P = 0.003 respectively). Preoperative MH size was lower and MS and FS were better in patients with a preserved junction line between the inner and outer segments of photoreceptors (IS/OS) (P = 0.045, P = 0.001, and P = 0.001 respectively). Better postoperative VA was correlated with better preoperative VA (P = 0.012, r = 0.513). Postoperative VA was correlated with MS and FS (P = 0.032, r = 0.449, and P = 0.019, r = 0.483 respectively). Greater foveal thickness was associated with better postoperative VA (P = 0.020, r = 0.482). CONCLUSION: Postoperative outer retinal layer integrity is associated with better final retinal sensitivity. Further studies are warranted to assess the role of SD-OCT and microperimetry in the pre- and postoperative evaluation of idiopathic macular holes.
