Surgical excision of subfoveal neovascular membranes in age-related macular degeneration

Abstract

We studied the results of surgical excision of ten consecutive subfoveal choroidal neovascular membranes in ten patients with age-related macular degeneration. The criteria for surgical eligibility included the following: (1) a clearly identifiable subfoveal membrane occupying the entire foveal avascular zone, (2) a visual acuity of 20/200 or worse, (3) minimal subretinal hemorrhage, and (4) an associated exudative macular detachment. Six of the ten patients showed visual improvement at one-month and three-month follow-up visits and seven showed visual improvement by the six-month examination. All ten maculae remained attached without recurrence of subfoveal neovascular membranes throughout the follow-up period. These results suggested that surgical excision is a viable alternative to laser photocoagulation in patients with subfoveal neovascularization in age-related macular degeneration.
