Effect of YAG Laser Iridotomy on IOP in Chronic Angle-closure Glaucoma

ABSTRACT

The effect of YAG laser iridotomy on intraocular pressure was investigated in 24 eyes of 19 patients with chronic angle-closure glaucoma prospectively for 3 months. In most cases(75%) the intraocular presure was reduced and the mean amount of reduction was 4.33mmHg. The amount of pressure reduction has no significant correlation with the extent of peripheral anterior synechiae and visual field loss. This result shows that laser iridotomy should be considered in the management of chronic angle-closure glaucoma irrespective of the extent of peripheral anterior synechiae and visual field loss and some amount of intraocular pressure reduction may be expected after laser iridotomy.
