The objective of this study was to observe the clinical effect of treatment for neovascular glaucoma of trabeculectomy combined with implantation of a silicon rubber slice. 28 patients (28 eyes) with neovascular glaucoma were treated by trabeculectomy combined with implantation of a piece of 3 to 5 mm silicon rubber, and the effect on intraocular pressure was observed. All patients were followed-up for 9 to 24 months (mean 18.3 months). The average intraocular pressure at the last visit was 21.65 mm Hg (range 17.30-28.97 mm Hg). The symptom of eye pain disappeared after surgery. Trabeculectomy with a piece of silicon rubber implantation is ideal therapy for neovascular glaucoma.
