Abstract

Purpose: To evaluate the outcomes of patients undergoing removal of an epi-retinal membrane with good starting visual acuity.

Methods: All patients undergoing pars plana vitrectomy with removal of an epi-retinal membrane by a single surgeon (GS) from the years 2012 - 2014 were evaluated. Patients who were phakic, had a baseline visual acuity of 20/50 or worse and those with less than six months of follow-up were excluded from the study. Charts were retrospectively evaluated for baseline characteristics, post-operative best corrected visual acuity (BCVA), intra-operative and post operative complications.

Results: Of the 40 patients included, only one (2.5%) developed an identifiable, serious post-operative complication related to surgery. That patient developed a vitreous hemorrhage with eventual return to baseline vision at the 3 month visit. No intra-operative complications were noted. Of the 40 patients, 19 (47.5%) had improved BCVA, 10 (25%) maintained their initial BCVA, 7 (17.5%) lost 1-2 lines and 4 (10%) lost 3 lines or greater at their last follow-up visit. Two of the four patients that lost 3 lines or greater had significant progression of dry age related macular degeneration. For most of the patients, BCVA stabilized by the 3 month visit, with few changes in future visits.

Conclusions: As vitrectomy becomes even safer with smaller gauge instruments, the indications for surgery continue to expand. Based on our results, surgery to remove an epi-retinal membrane is a reasonable option for those with significant metamorphopsia and highly symptomatic blurring of central vision, even with good baseline visual acuity. Complications rates were very low, 72.5% of patients either had improved or maintained their initial BCVA and half of those losing 3 or more lines had vision loss unrelated to their surgery.
