Glaucoma

Glaucoma is a group of eye conditions that damage the optic nerve, the health of which is vital for good vision. This damage is often caused by an abnormally high pressure in your eye. Glaucoma is one of the leading causes of blindness for people over the age of 60.

Glaucoma damages your optic nerve fibers over time.

Explanation:

Glaucoma is an eye disease caused by a buildup of intraocular pressure (IOP). Your eyes have clear liquid that flows in and out, but if you have glaucoma, this liquid doesn’t drain properly, causing this buildup of IOP pressure. As glaucoma progresses, it damages more and more of your optic nerve fibers, leading to vision loss.

1

With primary open-angle glaucoma, the fluid can still effectively flow back out of your eye.

Explanation:

With primary open-angle glaucoma, the fluid can’t effectively flow back out of your eye. In many cases, people don’t even know that they have glaucoma until they experience vision loss.

2

Angle-closure glaucoma occurs when the iris of the eye closes off the drainage angle completely.

Explanation:

Angle-closure glaucoma occurs when the iris of the eye closes off the drainage angle completely, causing an increase in IOP pressure and damage to the optic nerve.

3

Ocular hypertension is a result of high ocular pressure.

Explanation:

If you have a condition known as ocular hypertension, which is a result of high ocular pressure, your risk of developing glaucoma increases.

4

Drops are the second line of treatment of glaucoma.

Explanation:

Glaucoma treatment is centered around lowering your IOP in order to prevent further vision loss. Drops are the first line of treatment of glaucoma.

Diagnosing Glaucoma

Glaucoma is a potentially blinding disease that is characterized by progressive damage to the optic nerve of the eye.The optic nerve is like a cable that brings information the eye sees about the world and brings it to the brain, and when there’s damaging glaucoma, patients often first lose a bit of their peripheral vision, and as it progresses they can eventually lose their central vision.

This is a big problem because people don’t know that they’re affected. There are lots of different risk factors for glaucoma: increasing age, race, also increased intraocular pressure in the eye, family history can be important, as well as certain refractive areas of the eye.
