AIM: To evaluate the clinical effect of modified trabeculectomy for primary angle-close glaucoma.

METHODS: The modified trabeculectomy was performed on 114 cases(114 eyes)with primary angle-closure glaucoma. Lamellar sclera incision extended 1mm into clear corneal. Sodium hyaluronate was injected under sleral flap to deepen anterior chamber. Intraocular pressure(IOP), anterior chamber depth, filtering blebs, vision and complications were observed. The follow-up period ranged from 1 to 6 months.

RESULTS:Shallow anterior chamber was not occurred postoperatively. IOP was controlled in an ideal range. Functional blebs could form. Postoperative and preoperative visual acuity was significantly different.

CONCLUSION: IOP can be controlled effectively and postoperative complications were decreased after performed modified trabeculectomy. Modified trabeculectomy is easy, safe and effective, and has a high successful rate. It's a satisfactory surgery for primary angle-close glaucoma.
