The treatment of angle neovascularization with panretinal photocoagulation

Thirty-two eyes in 28 patients with anterior chamber angle neovascularization were prospectively treated with panretinal photocoagulation. Of 17 eyes that had less than 270 degrees angle closure, with an intraocular pressure of less than 40 mm Hg prior to treatment, 16 showed complete disappearance of the angle neovascularization and stabilization of the peripheral anterior synechiae after treatment. None of the 15 patients who had angle closure of 270 degrees or greater, or an intraocular pressure of above 40 mm Hg, showed any significant improvement after treatment. These results suggest that panretinal photocoagulation offers a highly effective means of dealing with early and moderately advanced cases of angle neovascularization.
