What is glaucoma?

Glaucoma is a group of eye diseases that can cause vision loss and blindness by damaging a nerve in the back of your eye called the optic nerve.  

The symptoms can start so slowly that you may not notice them. The only way to find out if you have glaucoma is to get a comprehensive dilated eye exam.  

There’s no cure for glaucoma, but early treatment can often stop the damage and protect your vision.  

What are the symptoms of glaucoma?

At first, glaucoma doesn’t usually have any symptoms. That’s why half of people with glaucoma don’t even know they have it.

Over time, you may slowly lose vision, usually starting with your peripheral vision. Because it happens so slowly, many people can’t tell that their vision is changing, especially at first.

What causes glaucoma?

Scientists aren’t sure what causes the most common types of glaucoma, but many people with glaucoma have high eye pressure. Treatments that lower eye pressure can help to slow the disease.

How is glaucoma diagnosed?

At Optical People, our experienced Optometrists include checks during a normal eye test which can help detect any signs of glaucoma.

These include an eye pressure test, visual field test, and an assessment of the optic nerve.  All of these tests help to determine whether any type of glaucoma exists and/or whether there is any damage to your vision.

It is recommended for most people to have an eye examination at least every two years, regardless of whether you have symptoms or established eye problems.

What’s the treatment for glaucoma?

There are different types of treatment for glaucoma depending on the diagnosis. If you have glaucoma, it’s important to start treatment right away. While it won’t undo any damage to your vision, treatment can stop it from getting worse. 

Medicines: Prescription eye drops are the most common treatment. They lower the pressure in your eye and prevent damage to your optic nerve.

Laser treatment: A procedure used by laser eye surgery specialists to drain the fluid and lower the pressure in your eye.

Surgery: If medicines and laser treatment don’t work, your optometrist might suggest surgery. There are several different types of surgery that can help the fluid drain out of your eye.
