Choroidal neovascularization secondary to vitrectomy for idiopathic epiretinal membrane: report of an unusual case.

Purpose: Epiretinal membranes (ERM) are a common finding in old patients. Pars plana vitrectomy is effective for removing ERM from the macula, but some postoperative complications are relatively frequent. In the present report, we describe a 73-year-old man in whom extrafoveal choroidal neovascularization developed four months after surgery.
Methods: Choroidal neovascularization was treated by argon laser photocoagulation.
Results: Six months after treatment, the choroidal neovascularization was obliterated, with no recurrence of ERM.
Conclusions: Choroidal neovascularization can be an unusual complication of ERM surgery, and should be suspected in case of poor visual outcome or recurrence of symptoms.
