Pseudoexfoliative glaucoma is a disease that develops in eyes affected by pseudoesfoliatio lentis syndrome, characterized by the flaking of the crystalline surface. The various fragments formed as a result of this process are deposited at the level of the angle between the iris and the cornea and obstruct the outflow pathways of the aqueous humor (trabeculate). Slowing or blocking the outflow of the liquid causes intermittent intraocular pressure elevations.
Pigmentary glaucoma, on the other hand, is a form of secondary open-angle disease, usually hereditary. It occurs due to the deposition of tiny pigment granules, coming from the iris and carried by the aqueous humor, in the cracks of the trabecular meshwork. Over time, this causes the clogging of the drainage channels of the aqueous humor, with increased intraocular pressure and glaucoma.
