Laser peripheral iridotomy is the same procedure used to preventively treat primary angle-closure suspects, or patients with narrow angles that are at risk for an angle-closure attack.
Laser peripheral iridotomy is the standard first-line treatment in closed angle glaucoma and eyes at risk for this condition. It has been used since 1984 both as treatment and prevention of the disease.
A laser peripheral iridotomy is a treatment used to treat angle closure. If you have healthy eyes, the fluid in your eye (aqeous humour) flows through your pupil into the front of your eye, and drains away through drainage channels called the trabecular meshwork.
During laser peripheral iridotomy, a laser makes 1 or 2 small holes through the iris (the colored part of the eye). This gives the fluid that normally circulates in the eye (the aqueous) an alternative pathway to the angle, where fluid drains out of the eye. This procedure is performed in several minutes as an outpatient in a surgery center.
Laser Peripheral Iridotomy, also abbreviated as LPI, is a preferred procedure for treating an angle-closure type of glaucoma. This type of glaucoma occurs due to a relative or absolute pupillary blockage. With its typical name, you would be assuming that its some new technique to treat angle-closure glaucoma, but you’re wrong.
Laser iridotomy is a surgical procedure that is performed on the eye to treat angle closure glaucoma, a condition of increased pressure in the front chamber (anterior chamber) that is caused by sudden (acute) or slowly progressive (chronic) blockage of the normal circulation of fluid within the eye.
