Pigmentary glaucoma is a type of secondary open angle glaucoma characterised by pigmentation of the trabecular meshwork, iris transillumination defects and pigments along the corneal endothelium. Individuals with the same findings who do not demonstrate optic nerve damage and/or visual field loss are classified as Pigment dispersion syndrome even if intraocular pressure is elevated.
Usually diagnosed on slit lamp and fundus examination by an ophthalmologist along with the measurement of IOP and confirmed after undergoing the approximate test for glaucoma including Gonioscopy,Automated perimetry,pachymetry and OCT of RNFL and ONH.

Pigmentary glaucoma is a type of secondary open angle glaucoma characterized by increased pigmentation in the trabecular mesh work, iris transillumination defects and pigments on the back of the corneal endothelium
It is treated by antiglaucoma medication, laser and surgery.
Long standing pigment dispersion causes structural damage to the trabecular mesh work which obstructs the aqueous outflow leading to increased IOP and glaucoma
Exercise has known to cause increase in pigment dispersion, thereby increasing the blockage in the trabecular mesh work and increasing the IOP
