[Photocoagulation in diabetic rubeosis iridis and neovascular glaucoma].

This retrospective study was performed to examine the effect of retinal coagulation on the course of iris neovascularization and neovascular glaucoma in patients with diabetic retinopathy. Sixty-four eyes in 42 patients were examined. Following retinal coagulation iris neovascularization regressed in 47 eyes (73%), while 17 eyes (27%) showed no improvement. In eyes with neovascular glaucoma, a drop in intraocular pressure was noted. Visual acuity decreased in 60% of the treated eyes. Regression of iris neovascularization was related to the number of burns applied.
