Glaucoma: The Silent Thief of Sight

Glaucoma is a group of eye conditions that damage the optic nerve, the nerve that carries visual information from the eye to the brain. It is a leading cause of blindness in the world, and it can affect people of all ages.

What causes glaucoma?

Glaucoma is caused by a build-up of fluid inside the eye. This fluid, called aqueous humor, is constantly produced by the eye to nourish and protect its tissues. However, if the fluid cannot drain out of the eye properly, it can build up and put pressure on the optic nerve. This pressure can damage the nerve fibers and lead to vision loss.

There are two main types of glaucoma:

Open-angle glaucoma is the most common type of glaucoma. It occurs when the drainage channels in the eye become clogged, which prevents the aqueous humor from draining out of the eye properly.
Closed-angle glaucoma is a less common type of glaucoma that occurs when the iris (the colored part of the eye) blocks the drainage channels in the eye. This can cause a sudden build-up of pressure in the eye, which can be very painful.

Who is at risk for glaucoma?

Anyone can develop glaucoma, but some people are at higher risk than others. These include people who:

Are over the age of 60
Have a family history of glaucoma
Are African American or Hispanic
Have diabetes
Have high blood pressure
Have a history of eye injuries
Take certain medications, such as steroids

What are the symptoms of glaucoma?

Open-angle glaucoma often has no symptoms in the early stages. As the condition progresses, people may experience:

Blurred vision
Patchy blind spots in the peripheral vision
Difficulty seeing in low light
Pain in the eyes
Headaches

Closed-angle glaucoma can cause a sudden onset of symptoms, including:

Severe pain in the eyes
Blurred vision
Halos around lights
Nausea and vomiting

How is glaucoma diagnosed?

Glaucoma is diagnosed with a comprehensive eye exam. The exam will include:

A visual acuity test to check your vision
A tonometry test to measure the pressure inside your eyes
A dilated eye exam to examine the optic nerve and retina

How is glaucoma treated?

The goal of glaucoma treatment is to lower the pressure inside the eye and prevent further damage to the optic nerve. Treatment may include:

Medication to reduce the production of aqueous humor or to improve the drainage of fluid from the eye
Laser surgery to create new drainage channels in the eye
Traditional surgery to create a new pathway for fluid to drain out of the eye

Can glaucoma be prevented?

There is no sure way to prevent glaucoma, but there are some things you can do to reduce your risk, such as:

Get regular eye exams, especially if you are at high risk for glaucoma
Control your blood pressure
Exercise regularly
Eat a healthy diet
Quit smoking

Glaucoma is a serious eye condition that can lead to blindness if it is not treated. However, with early diagnosis and treatment, most people with glaucoma can maintain their vision and live full, active lives.
