Clinical types of primary angle closure glaucoma

Abstract

There is no internationally adopted terminology for the clinical types of primary angle-closure glaucoma. Descriptions of three clinical types: 1. intermittent angle closure; 2. acute and subacute angle closure; and 3. creeping angle closure are presented with reasons for the division into and naming of these types. Chronic angle closure is not a distinct form but a late derivation from various types of angle closure.
