Abstract

Angle-closure is often erroneously considered synony- mous with pupillary block, the most common mecha- nism leading to acute or chronic iridocorneal apposition. However, abnormalities exist in structures and/or forces other than those related to pupillary block and may cause apposition despite a patent iridotomy. A 4-point classifi- cation of these mechanisms has been described, and includes mechanisms originating in the ciliary body, lens, or posterior segment. This review outlines the character- istics of angle-closure specific to each of these 3 levels.
