Glaucoma
Glaucoma is a disorder affecting the eye. It involves damage to the optic nerve, affecting vision and thus it can cause permanent damage to the affected eye. Without treatment, it can lead to blindness.

It is caused by An imbalance in fluid drainage leading to an increased intraocular pressure (IOP). This increased pressure pushes on the optic nerve and the retina. The continuous pressure leads to eventual ‘cupping’ of the nerve, leading to loss of vision. It starts with loss of peripheral vision, and then loss of central vision and eventual blindness. If the drain remains closed, the pressure accumulates giving the eye the appearance of frosted glass along with intense pain, nausea and vomiting.
