Pigmentary Glaucoma
Pigmentary glaucoma is caused by the mechanical blocking of the trabecular meshwork by iris pigment cells. The release of pigment cells is caused by the lens zonules rubbing the back of the
Another condition associated with pigment release is Pigmentary Dispersion Syndrome (PDS). With PDS, there is the same type of characteristic pigmentary release, but the intraocular pressures, visual fields, and optic nerve head all appear to be within normal limits. Many patients with PDS will eventually develop pigmentary glaucoma. What Is Glaucoma? | Types of Glaucoma | Diagnosing Glaucoma | Treatments | Research & Links | Glaucoma Home

iris and liberating the cells into the aqueous humor. The pigment then travels and is deposited on the trabecular meshwork, corneal endothelium, anterior lens capsule, and other areas on the lens. This blocks the flow of aqueous out of the anterior chamber and leads to increased intraocular pressure.
Pigmentary glaucoma is usually found bilaterally with an onset occurring usually between the ages of 20 to 40. This type of glaucoma has been found to have an association with the presence of myopia and occurs more frequently in males than females.
