Treatment of neovascular glaucoma with transscleral panretinal cryotherapy

Transscleral panretinal cryotherapy was used to treat six eyes with neovascular glaucoma. The media of each involved eye were sufficiently cloudy at the time of treatment to prevent adequate panretinal photocoagulation. A checkerboard pattern of eight 2.5-mm cryotherapy applications was placed in each quadrant. Five of the eyes were also treated with 180 degrees of cyclocryotherapy. Within 72 hours of treatment, the intraocular pressure in each eye returned to a controllable level. The iris neovascularization in each eye regressed or totally disappeared within six weeks.
