The term ocular hypertension usually refers to any situation in which the pressure inside the eye, called intraocular pressure, is higher than normal. Eye pressure is measured in millimeters of mercury (mm Hg). Normal eye pressure ranges from 10-21 mm Hg. Ocular hypertension is an eye pressure of greater than 21 mm Hg.

How common are iridotomy?

Iridotomy helps to prevent AACG by flattening the convex surface of the iris and widening the angle in patients with relative pupillary block. Success rates of laser iridotomy have been reported to be from 65-76%,7,8 and are relatively low in patients of east Asian descent.

Are narrow angles serious?

In some eyes, this angle is more acute than usual, and is called “narrow angle.” Eye’s with narrow angles are at risk of developing “angle closure” in which access to the drain is closed off completely and fluid that is being produced in the eye is trapped and cannot escape the eye, leading to a sudden increase in eye …

Family members of those with angle-closure glaucoma are 10 times more likely to develop it, so presently unknown genes must play some role. Smaller eyes are often “far-sighted”, so persons with hyperopia are more likely to get angle-closure.

How many years does LASIK last?
