Glaucoma Q & A

What causes glaucoma?

Glaucoma is the name of several eye diseases that damage your optic nerve. Most types of glaucoma are caused by high intraocular pressure (IOP), which is the pressure inside your eye that’s created by the fluid responsible for maintaining the eye’s shape.

When IOP stays higher than normal, it pushes against the optic nerve. Over time, untreated glaucoma progresses to cause vision loss and blindness.


What are the symptoms of glaucoma?

Glaucoma doesn't cause any symptoms at first. Your vision remains normal, and you won't have other symptoms like pain. Even without symptoms, however, IOP continues to increase, causing ongoing damage to the optic nerve.

Eventually, enough of the optic nerve is damaged to affect your vision. The first symptom of glaucoma is loss of your peripheral vision, or side vision. Over time, it affects your central vision, which interferes with your ability to see straight ahead, gradually worsening until your vision is lost.


What are the different types of glaucoma?

Your eye maintains normal pressure by maintaining the right amount of fluid. Fluid drains out of your eye at the same rate that fresh fluid is produced and released into the eye. Pressure increases when this system is out of balance.

The two most common types of glaucoma are:

Primary open-angle glaucoma (POAG)

POAG represents at least 90% of all cases of glaucoma. It develops when the primary drainage system, the trabecular meshwork, is partially blocked, increasing the amount of fluid inside your eye and raising IOP.

Angle-closure glaucoma

This type of glaucoma usually develops suddenly when the opening to the trabecular meshwork becomes blocked by the iris. Because it happens so quickly, and the rise in IOP is rapid, angle-closure glaucoma uniquely causes symptoms such eye pain, nausea and vomiting, headache, and blurred vision.


How is glaucoma treated?

Your treatment focuses on lowering IOP and keeping it within a normal range. The first line of treatment consists of eye drops containing medications that lower IOP by decreasing the production of fluid or improving drainage.

When you get routine eye examinations, Dr. Chase can see early changes in your IOP and optic nerve before you have symptoms. As a result, you can get treatment to lower your IOP and protect your vision.
