Glaucoma Glaucoma is a major cause of blindness in people over the age of 40. Those that have a higher risk of this disease include people with a family history of glaucoma, African Americans, and those who are very nearsighted or diabetic.

     The disease occurs when the internal pressure in your eyes increases enough that the nerve fibers in your optic nerve become damaged. The increase in pressure occurs when the passages that normally allow fluid in the eyes to drain become clogged. The cause of this is not known.

     Glaucoma usually develops gradually, painlessly and without any symptoms. There is a rare form of the disease that can occur rapidly. Symptoms may include blurry vision, loss of side vision, and pain or redness in the eyes.

      Though there is no prevention for glaucoma, if caught early it can be controlled. Once vision has been lost to this disease it cannot be restored, so early detection is very important.

      Treatment for glaucoma includes prescription eye drops and medicines that will lower the pressure in your eyes. Some cases require laser treatment or surgery to reduce the pressure.

      Dr. Howell recommends an annual eye exam for people at risk for glaucoma. The exam will include a test of the pressure in your eyes; an examination of the inside of your eyes and optic nerves; and a field test to check your center and side vision.
