A glaucoma is a group of eye diseases in which the water pressure (IOP) in the eye rises above normal, causing damage to the optic nerve (optic nerve), an organ that is vulnerable to damage during intraocular pressure. The eyes rise higher. The disease can often occur without any noticeable symptoms in its early stages. Left untreated, it can cause vision loss and damage to the retina of the eye. Glaucoma occurs in 2 to 3% of people over the age of 40, and 50% of them are not diagnosed in advance, but in the early stages, there is a loss. Vision in the peripheral region, if not treated in time, will result in permanent loss of vision.
