Treatment of Diabetic Neovascular Glaucoma by Transscleral Cyclophotocoagulation and Retinal Photocoagulation

Objective To observe the clinical results of transscleral diode laser cyclophotocoagulation and retinal photocoagulation for diabetic neovascular glaucoma.Methods Twelve cases(13 eyes) of diabetic neovascular glaucoma were treated by transscleral diode laser cyclophotocoagulation and retinal photocoagulation.All patients were followed up 6-12 months.The intraocular pressure(IOP),visual acuity and neovascularization of the iris after 6 months of treatment were analyzed.Results Pre-treatment IOP was 32-68 mmHg(1 mmHg=0.133 kPa),averaged 46.56 mmHg.Six months after treatment,IOP was 8-27 mmHg,averaged 13.18 mmHg.Visual acuity decreased in 2 eyes,increased in 4 eyes and remained unchanged in 7 eyes.Neovascularization of the iris disappeared in 7 eyes and regressed partly in 6 eyes.Conclusions The treatment of diabetic neovascular glaucoma by diode laser cyclophotocoagulation and retinal photocoagulation can reduce IOP and save visual acuity.It is a safe,simple and effective method.
