In order to evaluate the effect of Q-switched YAG laser iridotomy to the intraocular pressure, we performed the Q-switched Nd-YAG laser iridotomy in 39 eyes of 28 patients with angle closure glaucoma. Postoperative difference of the intraocular pressure was 27.5 +/- 27.0mmHg and the intraocular pressure was reduced. After 2 months, 12 eyes had needed one kind of anti-glaucomatous medication, 7 eyes had needed no medication, 6 eyes had needed two medications and 1 eye had needed three medications. Postoperative complications were iris bleeding(10 eyes), transient pressure rising(9 eyes), focal corneal opacities(2 eyes) and closure of iridotomy(2 eyes). These result shows that laser iridotomy should be considered in the management of angle closure glaucoma.
