Important Clue to Angle Closure Found

January 20, 2010

Why do only a fraction of narrow angles proceed to closure? The answer is in iris volume. In susceptible eyes,the iris acts like a sponge and increases in volumes, absorbing fluid as it dilates, and thus crowding the angle, while in most eyes, the iris volume decreases as it dilates, and the angle remains narrow and open. A fascinating insight by very clever researchers, who demonstrated the iris volume changes beautifully using OCT.
