[Combined phacoemulsificaion/membrane resection and macular edema].

PURPOSE: To evaluate the occurrence of macular edema (ME) after epiretinal membrane resection, managed either with simple vitrectomy or with combined vitrectomy and phacoemulsification. MATERIAL AND METHODS: Two groups of 12 patients had a vitrectomy for epiretinal membrane associated or not to a phacoemulsification. A fundus fluorescein angiography was performed pre and postoperatively and at least 3 months after the surgery. RESULTS: In the group of patients who had a simple vitrectomy, a ME was observed in 50% of the cases preoperatively and in 25% of the cases at the end of follow-up. In 3 cases, preoperative ME was worsened after the surgery. In the group of patients who were treated by a combined vitrectomy and phacoemulsification, a ME was observed in 25% of the cases preoperatively and in 50% of the cases at the end of follow-up. A de novo ME was observed in 3 cases. CONCLUSION: Combined vitrectomy and cataract surgery could allow a rapid recovery of visual acuity but might increase the occurrence of ME.
