Laser Peripheral Iridotomy (LPI) is a laser treatment for narrow angles, narrow angle glaucoma, and acute angle closure glaucoma. In these situations, the part of the eye responsible for draining fluid from the eye becomes narrow, causing increased intraocular eye pressure (IOP). This can happen suddenly or may occur over time.
How Does LPI Work?
During LPI treatment, a laser is used to target the narrow angles between the iris and cornea in an attempt to widen them and increase fluid flow.
This allows the eye to better regulate intraocular pressure.
IS LPI Right for My Glaucoma Management?
It is recommended that LPI is preformed after IOP has been regulated to a manageable level. However, it is the first course of action in acute angle closure situations.
While LPI is used to correct glaucoma-related issues related to angle narrowing that has already developed, the procedure is also used preventatively to discourage an acute angle closure event and closed-angle glaucoma.
