Know more about Glaucoma

What is Glaucoma ?

The term “glaucoma” is used to describe a variety of eye conditions that harm your optic nerve. It is the most typical type of optic nerve injury that causes visual loss.

Your eye is under pressure from this additional fluid, which gradually harms your optic nerve. Intraocular pressure (IOP), sometimes known as eye pressure, is the name of this force. Even when their eye pressure is normal, some people get glaucoma. Untreated or improperly managed glaucoma can cause blindness and irreversible vision loss.

How widespread is glaucoma?

An estimated 3 million Americans are thought to suffer from glaucoma, a common age-related eye condition. It is the second leading cause of blindness in the world, right after cataracts.

Types of glaucoma:
