Macular sensitivity and structure in epiretinal membranes 6 months after surgical treatment

Résumé

Purpose: To evaluate the evolution of macular sensitivity (MS) and its correlation with visual acuity (VA) and Spectral‐Domain Optical Coherence Tomography (SD‐OCT) in patients with idiopathic epiretinal membrane (ERM) at 3 and 6 months after surgical treatment. Methods: In this prospective, monocenter, interventional case series, we included 49 patients (49 eyes) with an idiopathic ERM scheduled for a surgical treatment. Among these patients, 34 were evaluated at 3 months (M3) and 32 at 6 months (M6) after ERM and internal limiting membrane removal. At each visit a measurement of ETDRS best‐corrected visual acuity, microperimetry and SD‐OCT were performed for all patients. Results: The MS was improved significantly from 11.7±2.1 dB preoperatively to 12.9±1.8 dB (p=0.001) and 13.3±1.9 dB (p=0.001) at M3 and M6 postop respectively. In the same time we observed an improvement of VA from 70.0±10.2 letters ETDRS at inclusion to 80.1±6.9 letters at M3 (p<0.0001) and 80.8±6.5 letters at M6 (p<0.0001). Macular thickness decreased significantly from 412.6±53.1 µm to 340.5±29.6 µm and 332.9±26.9 µm at M3 and M6 respectively. We found a significant correlation between pre and post operative MS at M3 (r=0.565; p=0.0002) and M6 (r=0.584; p=0.0001). A significant correlation between pre and post operative VA was also found at M6 (r=0.558; p=0.0003) but not at M3 (r=0.229; p=0.097). We did not find any significant correlation between the increase in MS and VA (r=0.286; p=0.112) and between MS improvement and macular thickness decrease (r=‐0.196; p=0.283). Conclusion: Complementary aspects of macular function were given by VA and MS measurements after ERM surgery.
