Abstract
- To find the factors that affect on the success rate of the trabeculectomy, we investigated 208 eyes of 158 patients with various types of glaucoma which had undergone trabeculectomy. The patients were followed up at least 3 month postoperatively. The criteria of success was maintenance of postoperative IOP below 21 mmHg. The total success rate was 89.4%. In young patients, the success rate was lower than that of older ones. The success rate of open angle glaucoma, acute angle closure glaucoma and chronic angle closure glaucoma were higher than that of congenital glaucoma and secondary glaucoma. Recently performed operation demonstrated higher success rate. The type of conjunctival flap, scleral flap and use of 5-fluorouracil were independent factors that affect on the success rate.
