Laser peripheral iridotomy was a treatment used for the narrow angle glaucoma. The doctors use an Nd:YAG laser to make a small hole in peripheral iris. This will improve the circulation of the fluid inside the eye & widens the anterior chamber angle. Fluid that was produced behind the iris has very easy access to the eye's internal drainage system. Rarely this lowers intraocular pressure, but that was not the primary goal of the laser peripheral iridotomy. The primary motto of the procedure was to lessen the risk of the acute angle-closure glaucoma.
