To the Editor.  —Peripheral iridectomy is the treatment of choice for pupillary block glaucoma and for prophylaxis of occludable iridocorneal angles. Argon laser iridectomy has fewer serious complications and has largely replaced surgical iridectomy. Complications following argon iridectomy include iritis, transient elevated intraocular pressure, failure to penetrate the iris, and closure of the iridectomy. Recent efforts to improve the success rate of laser iridectomy have led to the investigation of the neodymium (Nd)-YAG laser.1,2 Reports indicate an excellent patency rate, with generally minor and transient complications. The incidence of elevated intraocular pressure has been similar to that reported with the argon laser.We encountered four cases of markedly increased intraocular pressure related to Nd-YAG laser iridectomy. Three patients had chronic angle-closure glaucoma, and one had occludable angles with normal intraocular pressure. Previous laser iridectomy had been performed uneventfully in two contralateral eyes, one with an Nd-YAG laser, one with
