Background Laser peripheral iridotomy (LPI) is the preferred procedure for treating angle-closure glaucoma caused by relative or absolute pupillary block. LPI eliminates pupillary block by allowing the aqueous to pass directly from the posterior chamber into the anterior chamber, bypassing the pupil.
Yag Iridotomy-Laser Peripheral Iridotomy. Laser peripheral iridotomy is a treatment for narrow angle glaucoma. The surgeon uses an Nd:YAG laser to create a small hole in the peripheral iris.This improves the circulation of fluid inside the eye and widens the anterior chamber angle.ometimes this lowers the intraocular pressure, but that is not the primary goal of laser peripheral iridotomy. The primary goal of the procedure is to lessens the risk of acute angle-closure glaucoma. A small hole is visible in the peripheral iris.
