Purpose: To observe clinical effect of treatment for neovascular glaucoma using trabeculectomy combined with implantation of silicon rubber slice. Methods: 28 cases(28 eyes)with neovascular glaucoma were performed trabeculectomy combined with a piece of 3 × 5 mm silicon rubber implantation, and their lowing intraocular pressure effect was observed.Results: All patients were follow-up for 9 ～ 24 months (mean: 18.3 months). The average intraocular pressure at last visit was 21.65 mmHg (rang: 17.30 ～ 28.97 mmHg , 1mmHg = 0. 133 kPa). The symptom of eye pain was disappeared after surgery.Conclusion: Trabeculectomy with a piece of silicon rubber implantation is ideal therapy for neovascular glaucoma.
