Abstract

Purpose: To evaluate macular sensitivity (MS) change and its correlation with visual acuity (VA) and Spectral-Domain Optical Coherence Tomography (SD-OCT) in patients with idiopathic epiretinal membrane (ERM) at 3, 6 and 12 months after surgical treatment.

Methods: Prospective, monocenter, interventional case series. We included 49 patients (49 eyes) with an idiopathic ERM scheduled for a surgical treatment. Among these patients, 40 were evaluated at 3 and 6 months (M3, M6), and 31 at 12 months (M12) after ERM and internal limiting membrane removal. At each visit a measurement of best-corrected visual acuity (ETDRS), a microperimetry and a SD-OCT were performed for all patients.

Results: The MS significantly improved from 11.76 ± 2.16 dB to 13.68 ± 1.99 dB at M12 (p<0.0001). In the same time we observed an improvement of VA from 70.0 ± 10.2 letters ETDRS at inclusion to 81.9 ± 6.1 letters at M12 (p<0.0001). Macular thickness significantly decreased from 416.2 ± 53.9 µ to 303.7 ± 31.9 µ at M12. We found a significant correlation between pre and post operative VA at M12 (r=0.445; p=0.012). There was no significant correlation between pre and post operative MS at M12 (r=0.329; p=0.071). We found a significant correlation between the increase of MS and VA (r=0.516; p=0.003) but not between MS improvement and macular thickness decrease (r=-0.163; p=0.381). Among the 25 (80.6 %) patients with a MS improvement, 6 (24%) did not increase their VA. Conversely, among the 24 (77.4 %) patients with a VA increase, 4 (16.7 %) did not improve their MS.

Conclusions: VA and MS measurement are different but complementary aspects of macular function in the evaluation of patients with ERM.
