Purpose: to report the functional outcome of vitrectomy with epiretinal membrane (ERM) peeling and to assess the risks associated with this surgical procedure.
Methods: Retrospective study of 182 patients who underwent vitrectomy to alleviate visual loss and/or metamorphopsia due to ERM formation. The inclusion criteria were: primary vitrectomy and ERM peeling and at least 1 year of follow-up. Patients with previous vitreoretinal surgery, uveitis, age under 18 years and with a visual acuity of less than 20/400 prior to surgery, were excluded. Besides a comprehensive ophthalmic examination, a questionnaire was used to evaluate the subjective experiences of the 206 patients in this study.
Results: in this study, 184 eyes of 182 patients were included. The median preoperative best corrected visual acuity (BCVA) was 0.3 (range 0.1–0.5. In 79% of patients visual acuity improved by 2 Snellen lines or more. Sixty-two percent of patient noticed an improvement of the metamorphopsia. Within 26 months following vitrectomy, significant cataract developed in 96% of the patients. Almost 6% of the patients developed retinal detachment in the follow-up period.
Conclusion: The majority of patients experienced both an improvement of the visual acuity and metamorphopsia. Virtually all phakic patients develop significant cataract within 2 year following the procedure and retinal detachment is a relative frequent complication.
