To investigate the correlation between early foveal contour recovery after idiopathic epiretinal membrane (iERM) surgery and long-term visual prognosis.
Retrospective, interventional case series.
We retrospectively reviewed medical records of patients who had ERM surgery from June 2013 to June 2015. The patients were sorted into 2 groups according to foveal change within 1 month after ERM surgery: pit recovery group and no recovery group. Change of best corrected visual acuity (BCVA, logMAR) and central macular thickness (CMT) by optical coherence tomography (OCT) at 1, 2, 3, 6, 12 months after surgery compared to preoperative time were compared between 2 groups. And also the preoperative OCT features associated with foveal contour recovery postoperatively were analyzed.
49 patients were enrolled and number of patients in recovery group and no recovery group was 22 and 27, respectively. Visual improvements were better in recovery group at all time and showed statistically significant differences from no-recovery group at 2 and 12 months after surgery. CMT reductions were larger in recovery group at all time but there were no significant differences between 2 groups. Foveal contour recovery was more likely to occur in cases with lamellar hole, cystic change and without inner retinal thickening. In cases of pseudophakic ERM (4 eyes in recovery group, 8 eyes in no-recovery group), improvement of VA were also higher in recovery group and showed significant differences at 1, 2, 6 months after surgery.
Early foveal contour change after ERM surgery can be a prognostic factor of 1 year visual acuity.
