The visual outcome of peripapillary choroidal neovascular membranes.

Twenty eyes with age related peripapillary choroidal neovascular membranes were studied retrospectively to establish visual outcome in relation to treatment with argon laser, position and size. There was no statistical difference in final visual acuity in relation to laser treatment, size of membrane, nor position of the membrane at presentation. Despite these findings, there is evidence that laser treatment may delay the progression of visual loss.
