Normally intraocular fluid flows freely between the anterior and posterior sections of the eye (A). As pressure builds in the eye, this circulation is cut off (B). In laser iridotomy, a special lens is placed on the eye (C). A laser is used to create a hole in part of the iris (D), allowing fluid to flow more normally and intraocular pressure to return to normal (E). (surgeryencyclopedia.com)
Within a normal eye, the iris is in partial contact with the lens of the eye behind it. (surgeryencyclopedia.com)
thus, the iris is closer to the lens and more likely to adhere completely to the lens, creating a pupillary block. (surgeryencyclopedia.com)
