Endoscopic Laser Photocoagulation for Management of Neovascular Glaucoma

ABSTRACT

We studies 8 eyes of 7 patients with neovascular glaucoma from June 1, 1995 to May 31 1997 retrospectively in order to note the clinical characteristics of disease. The mean age of the patients was 54. 3 years and the mean period of follow up was 9.5 months. Predisposing factors were proliferative diabetic retinopathy [7 eyes] , central retinal vein occlusion [I eye]. Vision at first visit was mainly hand motion or finger counting. Vision after operation was increased in 4 eyes, but deteriorated to no light perception in 3 eyes. The mean IOP at preoperative period was 35mmHg, at just postoperative period 20mmlHg at I week after operation, 25mmHg at last follow-up. Neovascularization of anterior chamber and angle were regressed in 6 eyes, but progressed in 2 eyes. Additional medical treatment was needed in all 8 eyes after operation. To treat. the early neovascular glaucoma, we used endoscopic laser photocoagulation. The endoscopy was good for observing far peripheral retina, pars plana, ciliary body and posterior segment of iris. We found the endoscopic laser was suitable for wider photocoagulation of ischemic retina against corneal opacity, miosis, cataract and intraocular gas.
