What is Glaucoma?
Glaucoma is a group of diseases that may cause loss of vision. It occurs as a resuşt of a buildup of fluid in the eyeball. Normally, thşs fluid nourishes your eye and keeps it healthy. After the fluid circulates,it emties through a drain in the front of your eyye.İn people who have glaucoma the drain in the eye is blocked and the fluid cant run out of the eyeball.Instead, the fluid builds up and causes increased pressure in the eye.

How does increased pressure damage your eye?
The increased pressure destroys the nerve cells in the eye, which leads to vision loss. At first, you may have blind spots only in your peripheral (side) vision. If your glaucoma isn’t treated, your central vision will also be affected. Vision loss caused by glaucoma is permanent.

What are the symptoms of glaucoma?
The main symptom of glaucoma is vision loss, especially loss of peripheral vision. However, half of all people who experience loss of vision caused by glaucoma are not aware they have the disease. By the time they notice loss of vision, the eye damage is severe.

Rarely, an individual will have an acute (sudden or short-term) attack of glaucoma. In these cases, the eye becomes red and extremely painful. Nausea, vomiting and blurred vision may also occur.

Who gets glaucoma?
Risk factors for glaucoma include:

Being 40 years of age or older
Belong to certain ethnic groups, including black and Latino
A family history of glaucoma
High pressure in the eyes
Heart disease
Near-sightedness (it is difficult for you to see objects in the distance)

How do I know if I have glaucoma?
You won’t know you have glaucoma until you notice vision loss. Since glaucoma causes no symptoms other than vision loss, it is important that you have a complete eye exam by an ophthalmologist regularly. An ophthalmologist is a doctor who is trained to provide care for the eyes, including the diagnosis and treatment of glaucoma. Your ophthalmologist can measure your eye pressure, examine your optic nerve and evaluate your central and peripheral vision. Early diagnosis and treatment of glaucoma can prevent damage to the eye’s nerve cells and prevent severe vision loss.

How often should I have an eye exam?
People 18 to 60 years of age should have an eye exam every 2 years. After age 60, you should have an eye exam once a year.

What is the treatment for glaucoma?
The purpose of treatment is to lower the pressure in the eye to prevent further nerve damage and vision loss. Glaucoma is usually treated first with medicated eyedrops. Medicines that can be taken orally (in pill form) can also be prescribed if eyedrops alone don’t help relieve pressure.

If these treatments don’t work, your doctor may suggest surgery to relieve the pressure in your eyes.
