The incidence of vision problems increases as people age. Glaucoma is among the most common conditions and is the leading source of blindness in people over age 60. The term specifically refers to eye diseases that affect the vision by disrupting the optic nerve’s function. Here’s what you should know about this degenerative condition and how an eye doctor can help you.

4 FAQ About Glaucoma

What is glaucoma?

The optic nerve is located at the back of the eye. Over time, it can deteriorate and lose its integrity due to changes in eye pressure. As this level increases, the nerve becomes damaged, which can lead to gradual vision loss. The usual cause of increased eye pressure is an accumulation of aqueous humor—the fluid that drains through an angular point between the cornea and the iris. If the drainage system fails to function properly or your eyes produce too much aqueous humor, then the pressure will increase as the fluid collects.

Are there different types of glaucoma?

Open-angle glaucoma, which is the most common type, occurs when the drainage point becomes blocked. This causes a change in pressure within the eye and gradual damage to the optic nerve. 

Angle-closure glaucoma is the less common version. It develops when the iris extends outward and blocks the angular drainage point. This issue prevents fluid from draining, which causes a spike in pressure that leads to nerve damage and vision loss.

What are the signs that you might have glaucoma?

Usually, glaucoma doesn’t present any symptoms in its earliest stages. As the condition progresses, you may experience difficulty seeing peripherally or centrally. Eventually, glaucoma can lead to tunnel vision. Sometimes people develop an acute form of angle-closure glaucoma, which can present with severe eye pain, headache, nausea, vomiting, blurriness, and red eyes.

Is it treatable?

There is no specific treatment for glaucoma, but scheduling regular exams with your eye doctor is the most effective way to stay on top of your eye health. While the actual damage is not reversible, your provider can take steps to slow progression by prescribing pills or eyedrops. In some cases, surgical intervention or laser therapy may be useful in reducing pressure.
