Abstract

Purpose: To report unexplained severe central vision loss accompanied by a dense central scotoma as an uncommon complication following epiretinal membrane removal.

Methods: Retrospective, multicentred, case series.

Results: Six patients underwent uncomplicated vitrectomy surgery between 2000 and 2007 at four separate retina practices for removal of an epiretinal membrane. Preoperative vision ranged from 20/60 to 20/100, with a median of 20/70. On the first day postoperatively, all patients noted decreased vision ranging from counting fingers to light perception and were found to have a dense central scotoma. Posterior segment examination revealed a white, oedematous macula in all affected eyes. Vision improved minimally during the follow-up period, which ranged from 2 months to 5 years. The final vision ranged from 20/200 to hand movements. No anatomic or physiologic cause for the decreased vision and central scotoma was identified.

Conclusions: While uncommon, severe, permanent, central vision loss accompanied by a dense central scotoma can occur following epiretinal membrane removal and should be considered when assessing the risks and benefits of such surgery.
