Pigment dispersion syndrome (PDS) is an eye disorder that can lead to a form of glaucoma known as pigmentary glaucoma. It takes place when pigment cells slough off from the back of the iris and float around in the aqueous humor .
Primary angle closure glaucoma: Once any symptoms have been controlled, the first line (and often definitive) treatment is laser iridotomy. This may be performed using either Nd:YAG or argon lasers, or in some cases by conventional incisional surgery. The goal of treatment is to reverse and prevent contact between the iris and trabecular meshwork.
Argon laser trabeculoplasty is effective in the management of corticosteroid and pigmentary glaucoma. [2] However, this is often contraindicated due to high rates of failure in patients with uveitic glaucoma. [6] For uveitic glaucoma, treatment with selective laser trabeculoplasty is associated with fewer adverse effects and risks of failure. [6]
Pigmentary changes in the retina – In addition to the pigmented cells in the iris (the colored part of the eye), there are pigmented cells beneath the retina. As these cells break down and release their pigment, dark clumps of released pigment and later, areas that are less pigmented may appear [ citation needed ]
Those with moderate amounts of myopia are more likely to have pigment dispersion syndrome or pigmentary glaucoma. [84] High myopia usually describes myopia of −6.00 or more. [65] [85] People with high myopia are more likely to have retinal detachments [86] and primary open angle glaucoma. [87]
The initial retinal degenerative symptoms of retinitis pigmentosa are characterized by decreased night vision and the loss of the mid-peripheral visual field. [4] The rod photoreceptor cells, which are responsible for low-light vision and are orientated mainly in the retinal periphery, are the retinal processes affected first during non ...
