Abstract

Abstract : Purpose: To determine the frequency of epiretinal membranes (ERM) in eyes with primary open-angle glaucoma subjected to trabeculectomy. Methods: We conducted a retrospective study on patients subjected to trabeculectomy with at least a 6-month follow-up. Ophthalmologic examination and spectral-domain optical coherence tomography (SD-OCT) were analyzed. Eyes with previous surgical or laser treatments or other pathologies (other than glaucoma and ERM) were excluded. Results: A total of 50 eyes (40 patients) were included in this study. The mean follow-up time after surgery was 27.8 months. After surgery, 9 eyes (18%) had preretinal macular fibrosis and 19 eyes (38%) had cellophane macular reflex. Of the 16 eyes with a preoperative macular SD-OCT, 3 (18.8%) developed ERM and 4 (25%) progressed from cellophane macular reflex to preretinal macular fibrosis, after surgery. The ERM frequency did not differ significantly between eyes subjected to trabeculectomy with or without the use of antimetabolites ( P =0.08), or between eyes subjected to simple or combined surgery (phacotrabeculectomy) ( P =0.09). Conclusion: Trabeculectomy may predispose one to the appearance and progression of ERM. Further studies are needed to clarify this intriguing relation.
