Glaucoma is a group of eye diseases that can cause vision loss and blindness by damaging your optic nerve (nerve that passes information between the eyes and the brain).
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 examination.
There’s no cure for glaucoma, but early treatment can often stop the damage and protect your vision.
There are many different types of glaucoma, but the most common type in India is called open-angle glaucoma that’s what most people mean when they talk about glaucoma. Other types of glaucoma are less common, like angle-closure glaucoma and congenital 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 side (peripheral) vision — especially the part of your vision that’s closest to your nose. Because it happens so slowly, many people can’t tell that their vision is changing, especially at first.
But as the disease gets worse, you may start to notice that you can’t see things off to the side anymore. Without treatment, glaucoma can eventually cause blindness.
Anyone can get glaucoma, but some people are at higher risk. You’re at higher risk if you:
Angle-closure glaucoma can cause these sudden symptoms:
If you have these symptoms, go to your doctor or an emergency room now. There’s no way to prevent glaucoma. That’s why eye exams are so important — so you and your doctor can find it before it affects your vision.
Eye doctors can check for glaucoma as part of a comprehensive dilated eye exam. The exam is simple and painless — your doctor will give you some eye drops to dilate (widen) your pupil and then check your eyes for glaucoma and other eye problems. The exam includes a visual field test to check your peripheral (side) vision.
Some people with high eye pressure don’t get glaucoma — and there’s a type of glaucoma that happens in people with normal eye pressure
The amount of eye pressure that’s normal varies by person — what’s normal for one person could be high for another
Doctors use a few different types of treatment for glaucoma, including medicines (usually eye drops), laser treatment, and surgery.
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. To lower pressure in your eye, doctors can use lasers to help the fluid drain out of your eye. It’s a simple procedure that your doctor can do in the office.
Surgery. If medicines and laser treatment don’t work, your doctor might suggest surgery. There are several different types of surgery that can help the fluid drain out of your eye.
Talk over your options with your doctor. While glaucoma is a serious disease, treatment works well.
If you’re having trouble with everyday activities because of your vision loss, ask your doctor about low vision services or devices that could help
Encourage family members to get checked for glaucoma, since it can run in families
