THE RESULTS OF PHOTOCOAGULATION TREATMENT ON RUBEOSIS IRIDIS AND NEOVASCULAR GLAUCOMA IN EALES-DISEASE

In the study of 871 eyes with Eales disease, 12 eyes were found to hav e rubeosis iridis and neovascular glaucoma. Seven of these 12 eyes had retinal neovascularization and rubeosis iridis, 2 had disc neovascula rization and open-angle neovascular glaucoma, 1 had disc neovasculariz ation and closed-angle neovascular glaucoma, and 2 had retinitis proli ferans and closed-angle neovascular glaucoma. Photocoagulation was und ertaken for the underlying retinal disorder. Rubeosis iridis regressed completely or partially in all the eyes when retinal neovascularizati ons were completely closed. There was a partial regression of angle ne ovessels in eyes with open-angle neovascular glaucoma following panret inal photocoagulation. The intraocular pressure was kept less than 20 mmHg with topical antiglaucoma medication. Panretinal photocoagulation did not cause regression of the disc neovascularization and a drop in intraocular pressure in the other eye with closed-angle neovascular g laucoma and disc neovascularization. Areas between the fibrous prolife rations were photocoagulated in eyes with retinitis proliferans, but l aser treatment did not alter the course of either the retinal disease or neovascular glaucoma.
