Abstract

We used argon laser gonioplasty to treat angle-closure glaucoma unrelieved by patent iridectomy. Laser energy (mean; 30 spots, 723 mW, and 0.2 second) was applied to the peripheral iris stroma to open the anterior chamber angle. Twenty of 32 eyes were successfully treated. After a median follow-up period of 18 months, 17 of these 20 successfully treated eyes (85%) had an intraocular pressure less than or equal to 19 mm Hg, and 19 of these 20 successfully treated eyes (95%) had an intraocular pressure less than or equal to 21 mm Hg. The 20 successfully treated eyes had a median duration of angle closure of 12 days. Twelve unsuccessfully treated eyes had a median duration of angle closure of 90 days. All successfully treated eyes had more than 50% of the treated angle opened by argon laser gonioplasty and all but three successfully treated eyes had more than three clock hours opened by argon laser gonioplasty. Argon laser gonioplasty may be successful in treating angle-closure glaucoma unrelieved by iridectomy, especially in cases that are recognized and treated soon after onset.
