These medications reduce eye pressure by increasing the drainage of intraocular fluid through the trabecular meshwork. Cholinergics can be used alone or combined with other glaucoma medications. A combination of medications can help control how much fluid is produced in the eye and increase the amount of fluid that drains out of the eye. Many people who use these medications complain of dim vision, especially at night or in darkened areas such as movie theaters.
This is due to constriction of the pupil. Miotics increase drainage of intraocular fluid by making the pupil size smaller, thereby increasing the flow of intraocular fluid from the eye.
Was this helpful? Many people with angle-closure glaucoma develop it slowly. This is called chronic angle-closure glaucoma. With open-angle glaucoma, there are no warning signs or obvious symptoms in the early stages. As the disease progresses, blind spots develop in your peripheral side vision. Most people with open-angle glaucoma do not notice any change in their vision until the damage is quite severe. Your ophthalmologist can tell you how often you should be examined.
People at risk for angle-closure glaucoma usually show no symptoms before an attack. Some early symptoms of an attack may include blurred vision, halos, mild headaches or eye pain. People with these symptoms should be checked by their ophthalmologist as soon as possible. An attack of angle-closure glaucoma includes the following:. People with "normal tension glaucoma" have eye pressure that is within normal ranges, but show signs of glaucoma, such as blind spots in their field of vision and optic nerve damage.
Some people have no signs of damage but have higher than normal eye pressure called ocular hypertension. These patients are considered "glaucoma suspects" and have a higher risk of eventually developing glaucoma. Some people are considered glaucoma suspects even if their eye pressure is normal. For example, their ophthalmologist may notice something different about their optic nerve.
Most glaucoma suspects have no symptoms. That is why you need to be carefully monitored by your ophthalmologist if you are a glaucoma suspect. An ophthalmologist can check for any changes over time and begin treatment if needed. Pigment dispersion syndrome PDS happens when the pigment rubs off the back of your iris.
This pigment can raise eye pressure and lead to pigmentary glaucoma. Some people with PDS or pigmentary glaucoma may see halos or have blurry vision after activities like jogging or playing basketball.
Talk with an ophthalmologist about your risk for getting glaucoma. People with more than one of these risk factors have an even higher risk of glaucoma.
The only sure way to diagnose glaucoma is with a complete eye exam. A glaucoma screening that only checks eye pressure is not enough to find glaucoma. Glaucoma has no symptoms in its early stages. In fact, half the people with glaucoma do not know they have it!
Having regular eye exams can help your ophthalmologist find this disease before you lose vision. Glaucoma damage is permanent—it cannot be reversed. But medicine and surgery help to stop further damage.
To treat glaucoma, your ophthalmologist may use one or more of the following treatments. Glaucoma is usually controlled with eyedrop medicine. Used every day, these eye drops lower eye pressure. Some do this by reducing the amount of aqueous fluid the eye makes. Others reduce pressure by helping fluid flow better through the drainage angle. Glaucoma medications can help you keep your vision, but they may also produce side effects. Purchase this article with an account. Open Access.
