Other Types of Glaucoma such as Pigmentary Dispersion Glaucoma,Pseudoexfoliation Glaucoma and Trauma-related glaucoma


Pigmentary Dispersion Glaucoma

It typically occurs in young, middle age patient with myopia. There is abnormal contact between the back of the iris and the lens which will lead to continuous shedding of pigments from the iris and deposition of iris pigments all over the anterior segment, causing blockage of trabecular meshwork and high IOP.

This type of glaucoma is usually like POAG and come in chronic form but some times there are triggers like physical activity that will cause sudden increase in pigmentation with high I.O.P. In this form it will be like closure angle glaucoma.

Pseudoexfoliation Glaucoma

Pseudoexfoliation occurs in old age and it affects female more than male. It is a form of open angle glaucoma.

There is whitish fibrillar materials that build up on anterior part of the lens and related structures like iris, zonules and on the angle.

The origin of these materials is unknown and the continuous shedding of them will accumulate in the angle and block the drainage of aqueous through trabecular meshwork leading to high I.O.P. The pseudoexfoliation syndrome is bilateral disease in most of the cases but it is asymmetrical.

Trauma-related Glaucoma

Blunt trauma, penetrating trauma and chemical burn of the eye can lead to the development of glaucoma by disrupting the angle of the eye.
