Laser Iridotomy
Laser iridotomy
uses a focused beam of light to create a hole on the outer edge, or rim,
of the iris, the colored part of the eye. This opening allows fluid,
aqueous humor, to flow between the anterior chamber, the front part of
the eye, and the area behind the iris, the posterior chamber. This
opening may decrease pressure in the eye and usually prevents sudden
buildup of pressure within the eye, which occurs during an episode of
acute closed-angle glaucoma.
