Plateau iris syndrome is a relatively uncommon form of primary angle closure glaucoma that is seen more often in younger adults than pupillary block angle-closure glaucoma. Normal-tension glaucoma (NTG), also known as low tension or normal pressure glaucoma, is a form of glaucoma in which damage occurs to the optic nerve without eye pressure exceeding the normal range. T2: Tumor has grown into the ciliary body or choroid (or both). In angle closure glaucoma, increased intraocular pressure is caused by impaired outflow facility secondary to appositional or synechial closure of the anterior chamber drainage angle . George Coats in 1908 described the histopathological features of enucleated eyes with massive exudation.

Glaucoma was long defined as gradual vision loss due to elevated pressure in the eye. This subtype of glaucoma usually entails several mechanisms that interplay to produce increased intraocular pressure (IOP) and it is important to consider all the pathophysiological mechanisms leading to increased IOP as they influence management of patients. The angle closure may occur in an acute or chronic form. The result is a condition called CLARE. Although angle-closure glaucoma (ACG) only accounts for 26% of all glaucoma, it is expected that angle-closure glaucoma will affect 87% of Asian glaucoma patients, with bilateral blindness .
