Laser Iridotomy, Explained
Laser Iridotomy is a surgical eye treatment which is done in our Manhattan offices to treat angle closure glaucoma, a condition of increased pressure in the anterior chamber (front chamber) caused by acute (sudden) or chronic (slowly progressive) blockage of the normal circulation of fluid inside the eye. The block occurs at the angle of the anterior chamber that is formed by the junction of the cornea with the iris, which causes the intraocular pressure to build up. Laser Iridotomy at Eye Care on 5th is a highly effective procedure for treating most types of angle closure or narrow angle glaucoma.
This treatment is also performed prophylactically (preventively) on asymptomatic patients with narrow angles, and those with pigment dispersion. Individuals with a narrow angle usually have a higher risk of an acute angle closure, especially upon dilation of the eye. Pigment dispersion is a condition in which the iris pigment is shed and is dispersed throughout the anterior part of the eye. If the dispersion occurs because of bowing of the iris (the case in 60% of patients with pigment dispersion) a laser iridotomy at Eye Care on 5th will decrease the bowing or concavity of the iris and subsequent pigment dispersion. That decreases the risk of developing pigmentary glaucoma, -- a condition when the dispersed pigment may clog the trabecular meshwork.
Laser Iridotomyat Eye Care on 5th is also performed on the other eye of a patient who has an angle closure of one eye, since the probability of an angle closure in the second eye is 50%.
