AIM:To evaluate the clinical curative effect of modified trabeculectomy combined with interscleral drainage pond forming for the treatment of over 60 years old patients with acute angle-closure glaucoma(AACG). METHODS:A total of 73 patients 73 eyes aged over 60 of AACG underwent modified trabeculectomy combined with interscleral drainage pond forming. Anterior chamber depth, intraocular pressure, bleb shape and so on were observed after operation. RESULTS:About 3 to 36 months after surgery mean IOP was 12.5±4.8mmHg, significantly lower than that before surgery. Postoperative 75% (55/73) affected eyes had visual acuity improved. 96% (70/73)blebs were type Ⅰ, Ⅱ functional filtering bleb. Main complications were early shallow anterior chamber and hypotony in(18%, 13/73) affected eyes. CONCLUSION:Modified trabeculectomy combined with interscleral drainage pond forming is an effective way for the treatment of over 60 years old patients with AACG.
