Types of Glaucoma

Primary Open Angle Glaucoma (POAG) (H40.1)
In the UK and Europe, this is the commonest form of glaucoma. In Asia, angle-closure glaucoma is a much more common form.

Normal Pressure Glaucoma
This type of glaucoma is more likely to go undiagnosed, as intraocular pressures are always found to be normal.

Angle Closure Glaucoma
Angle closure glaucoma is also known as closed angle glaucoma, narrow angle glaucoma, and pupillary block glaucoma. Typically this type of glaucoma occurs in adult life, in those over age 40. The lens of the eye gets slightly bigger (thicker) over years, and this leads to occlusion of the drainage angle in those with already narrow angles (e.g. those with shorter than average eyes). Angle closure occurs as two varieties:

    1. Acute Angle Closure Glaucoma
    2. Chronic Angle Closure Glaucoma
