Angle closure glaucoma

What it means

A type of glaucomatous optic neuropathy in an eye that has evidence of angle closure (i.e. significant iridotrabecular contact).

Evidence of optic nerve damage can include s optic disc abnormalities (Vertical cup:disk ratio over the 97. 5th percentile in the normal population), visual field defects. The role of increased intraocular pressure (IOP) in glaucoma is debated, but an IOP exceeding the 99. 5th percentile of the normal population may be considered to support the diagnosis.
