Glaucoma Pigmentario

Glaucoma Pigmentario


Pigment dispersion syndrome is caused by the fibres supporting the crystalline lens rubbing away pigment from the under-side of the iris. It is most common in younger myopic males. The pigment sticks to various structures of the eye, such as the crystalline lens, the cornea and the trabecular meshwork which is the drainage area where aqueous fluid is leaves the eye. Obstruction of the trabecular meshwork by the pigment, increases the resistance of aqueous passing through the Trabecular Meshwork. Over time, this causes the pressure in the eye to increase. Therefore, if you suffer from Pigment Dispersion Syndrome (PDS), then you are at risk of developing Pigmentary Glaucoma, where increased eye pressure causes to damage of the optic nerve and your field of vision. Medical treatment of pigmentary glaucoma is similar to the treatment for Primary Open Angle Glaucoma. Your Ophthalmologist will advise on the most appropriate treatment for you, which usually involves eye drops, laser treatment and sometimes surgery.
