4. Pigmentary Glaucoma

A broad term describing a variety of eye conditions affecting the optic nerve is Glaucoma, and it can be quite serious. Occurring due to fluid moving in and out of the tiny chamber in front of the eyes, it could lead to vision loss and even blindness.

“Fluid moves in and out of this chamber, nourishing the tissue there. This fluid flows out of the eye through a spongy meshwork that acts as a drain,” says Healthline.

Another form of glaucoma, known as pigmentary glaucoma, occurs when a person develops pigment dispersion syndrome. While the symptoms for both these conditions are similar, the latter can also cause peripheral vision loss, meaning it would be difficult for the patient to see out of the side of their eyes.

“With pigmentary glaucoma, these pigment granules block normal fluid flow through the front chamber of the eye. This causes glaucoma, wherein increased pressure in the eye can lead to vision loss,” says LiveStrong. “The dispersion of pigment from the iris can cause eye color changes, and the two eyes may be different colors if they are affected unequally.”
