A condition known as glaucoma affects the optic nerve permanently and eventually leads to “Tunnel Vision.” Glaucoma is brought on by an increase in ocular pressure brought on by the drainage channel’s obstruction. A kind of secondary open-angle glaucoma known as pigmentary glaucoma is characterised by pigment that leaks from the iris and obstructs the eye’s drainage angle.

Pigmentary glaucoma may be caused by the iris’s (the colored portion in front of the eye) concave surface resulting in Iris pigment epithelial cell disruption, and granules of pigment are released that result in reduced outflow and increased IOP which temporarily overpowers the trabecular meshwork (the drainage of the eye). Chronically high IOP and secondary glaucoma brought on by trabecular meshwork causes pathological changes over time.

Initially Pigmentary glaucoma may cause no overt symptoms. However, over time peripheral vision may be lost. Halos and visual impairment may also be seen. These are brought on by increased intraocular pressure (IOP) which may be exacerbated by hard exercise or exposure to the dark. It has been demonstrated that exercise encourages an increase in pigment dispersion, which raises IOP and increases trabecular meshwork blockage. Eventually, they may be central vision also due to the complete damage of the optic nerve. 

Pigmentary glaucoma may be diagnosed following an ophthalmologist carrying out a slit lamp and retinal examination, determining the intraocular pressure. Conventional glaucoma diagnostic investigations, like gonioscopy, automated perimetry, pachymetry, and OCT, are also used to confirm this condition.

Myopia (nearsightedness), thin corneas family background are all risk factors for Pigmentory glaucoma. Moreover, males in their 30’s are more prone to Pigmentory glaucoma. Abrupt and intense exercise increases the release of pigments resulting in progression of Pigmentory glaucoma.

Unfortunately, it is difficult to decrease or stop iris pigment release. Hence, in treatment and management of glaucoma the goal is to lower eye pressure. A decrease in fluid entering the eye or an increase in fluid draining out of the eye to lower eye pressure can be obtained using eye pressure-lowering medication. Moreover, Top of Form

molaser treatment, or glaucoma surgery can also lower eye pressure. Depending on the severity of the problem, surgical treatments range from outpatient laser therapy to incisional surgery in the operating room.
