What is Glaucoma?

Glaucoma is a leading cause of blindness in the U.S. It occurs when the pressure inside the eye rises, damaging the optic nerve and causing vision loss. The condition often develops over many years without causing pain or other noticeable symptoms – so you may not experience vision loss until the disease has progressed.

Glaucoma Signs and Symptoms

Sometimes symptoms do occur. They may include:

• Blurred vision
• Loss of peripheral vision
• Halo effects around lights
• Painful or reddened eyes

People at high risk include those who are over the age of 40, diabetic, near-sighted, African-American, or who have a family history of glaucoma.

Glaucoma Test

To detect glaucoma, your physician will test your visual acuity and visual field as well as the pressure in your eye. Regular eye exams help to monitor the changes in your eyesight and to determine whether you may develop glaucoma. Various treatments for glaucoma are presented, all with an aim to lower pressure inside the eye: eye drops; laser procedures; surgical procedures.

Glaucoma Evaluation

During a glaucoma evaluation, Dr. Roberts may perform some of the following tests.

• Tonometry.
• Gonioscopy.
• Ophthalmoscopy.
• Visual field test.
• Photography
• Special Imaging

Glaucoma Treatment

There are a number of treatment options available, that are designed to slow down, or stop damage to the eye that is caused by glaucoma. While vision that has already been lost due to glaucoma can not be recovered, these treatments can stop vision loss from getting worse. Your eye care professional may suggest medicated eye drops, a laser procedure, or a surgical procedure, to treat glaucoma. These treatments all have a common goal; to lower pressure inside of the eye, and prevent further damage to the optic nerve. Prescription eye drops lower pressure inside of the eye, by decreasing the amount of fluid the eye produces, or by helping fluid leave the eye more easily. Laser procedures can lower eye pressure by relieving blockage in the drain mechanism of the eye. In some cases, lasers are also used to create new drainage channels inside the eye, when there is an obstruction to the normal flow of fluid. Surgical procedures lower eye pressure by creating an opening in the wall of the eye, so the fluid can easily escape. Another surgical approach is to implant a tube called a shunt, to channel fluid out of the eye. Your treatment plan will depend on the type of glaucoma you have, how far it has advanced, and your general health. Dr. Roberts will determine the best approach for you.
