Abstract
BACKGROUND AND OBJECTIVE: To assess the long-term results of Nd:YAG laser iridotomy in the treatment of patients with primary angle-closure glaucoma and occludable angles to evaluate the risk-benefit ratio and the role of gonioscopy in predicting the outcome after Nd:YAG laser iridotomy. PATIENTS AND METHODS: The records of 138 consecutive patients (231 eyes) who underwent Nd:YAG laser iridotomy in one hospital during 3 years (from 1989 to 1991) were reviewed. The mean follow-up period was 51 months. RESULTS: Of all eyes, 25.1% were treated for chronic angle-closure glaucoma and 10.8% were treated for acute angle-closure glaucoma; most eyes (64.1%) underwent prophylactic iridotomy for occludable angles. Decreased intraocular pressure (IOP) was noted in most eyes after Nd:YAG laser iridotomy; only 10 eyes required further filtration surgery. Visual acuity was unchanged or improved in 97.9% of all eyes at the 6-month visit. Cataract progression was primarily responsible for those eyes with decreased acuity. Ninety-seven percent of eyes had quantitatively wider angles after laser treatment; 8 of 14 eyes with peripheral anterior synechiae of more than 270° underwent further surgery to control IOP. Transient elevated IOP and iris bleeding occurred in 23.5% and 12.2% of the eyes, respectively; other complications were rare. CONCLUSION: Nd:YAG laser iridotomy is a safe and effective procedure for the treatment and prevention of angle-closure glaucoma. Gonioscopy is useful to predict the outcome after Nd:YAG laser iridotomy.
