Panretinal cryopexy was used for the treatment of 15 eyes with neovasc
ularization of the anterior segment, treated with panretinal photocoag
ulation in the past. The eyes were classified preoperatively according
to grade of neovascularization of the iris and anterior chamber angle
using Weiss' and Gold's device system. Four eyes had rubeosis iridis
with normal intraocular pressure and 11 had neovascular glaucoma. Rube
osis was secondary to proliferative diabetic retinopathy and/or centra
l retinal vein occlusion. Nine eyes with grade 0, I and II neovascular
ization showed regression of neovascularization and controlled intraoc
ular pressure. Six eyes with grade IV showed regression of neovascular
ization but uncontrolled intraocular pressure. All those eyes presente
d extensive peripheral anterior synechias.
