What is Glaucoma
Glaucoma is an eye disorder that cause damage to the optic nerve that carries information from the eye to the brain. Glaucoma usually has few or no initial symptoms.
In most cases, glaucoma is associated with higher than normal pressure inside the eye , a condition called ocular hypertension. But it also can occur when intraocular pressure (IOP) is normal. If untreated or uncontrolled, glaucoma first causes peripheral vision loss and eventually can lead to blindness.
And because most cases of glaucoma have few or no early symptoms, about half of people with glaucoma don’t know they have it.
Glaucoma is the second-leading cause of blindness in the Western world (behind macular degeneration), and the second-leading cause of blindness worldwide (behind cataracts).
