Kasschau 820 solutions At a glance: 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. There are many different
types of glaucoma, but the most common type in the United States is called open-angle glaucoma — that’s what most people mean when they talk about glaucoma. Other types 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 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: Talk with your doctor about your risk for glaucoma, and ask how often you need to get checked. If you’re at higher risk, you need to get a comprehensive dilated eye exam every 1 to 2 years. Angle-closure glaucoma can cause these sudden symptoms: If you have any of these symptoms, go to your doctor or an emergency room now. What causes glaucoma?Scientists aren’t sure what causes the most common types of glaucoma, but many people with glaucoma have high eye pressure — and treatments that lower eye pressure help to slow the disease. 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. How will my eye doctor check for glaucoma?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 side vision.
Did you know?Glaucoma can happen in 1 eye or both eyes 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 Normal eye pressure varies by person — what’s normal for 1 person could be high for another What’s the treatment for glaucoma?Doctors use 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. Treatment won’t undo any damage to your vision, but it 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. Learn more about glaucoma medicines 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.

Glaucoma ResourcesLast updated: April 21, 2022 Which statement is correct about glaucoma?The answer is D. This option is the only correct statement about glaucoma. Vision loss is NOT reversible when it occurs in glaucoma but it's permanent…eye drops can prevent further progression. Glaucoma occurs due to INCREASED intraocular pressure (NOT decreased), and there is NO cure for glaucoma.
What are three symptoms of glaucoma?What are the symptoms of glaucoma?. Eye pain or pressure.. Headaches.. Rainbow-colored halos around lights.. Low vision, blurred vision, narrowed vision (tunnel vision) or blind spots.. Nausea and vomiting.. Red eyes.. What are the main causes of glaucoma?Glaucoma is a chronic, progressive eye disease caused by damage to the optic nerve, which leads to visual field loss. One of the major risk factors is eye pressure. An abnormality in the eye's drainage system can cause fluid to build up, leading to excessive pressure that causes damage to the optic nerve.
What is glaucoma symptoms and treatment?Most people with glaucoma have no early symptoms or pain. Visit your eye doctor regularly so they can diagnose and treat glaucoma before you have long-term vision loss. If you lose vision, it can't be brought back. But lowering eye pressure can help you keep the sight you have.
