Glaucoma Evaluation

What is Glaucoma?

Glaucoma refers to a group of related eye conditions that are often caused by a buildup of fluid in the front of your eye. The fluid buildup results in increased pressure in your eye that can damage your optic nerve.

Your optic nerve has about one million nerve fibers that transmit signals from your eye to your brain, but you can lose some of these nerve fibers due to the consistent pressure caused by fluid buildup.

At that point, progressive deterioration and vision loss can occur. Some of this vision loss is irreversible.

There are numerous types of glaucoma, but the most common is open-angle glaucoma, where the optic nerve damage is painless and happens over a long time.

Glaucoma is a gradual disease. Keeping up to date with your comprehensive eye exams allows Dr. Weisz to help you achieve the best eye health possible and detect any signs of disease before they progress.

How is Glaucoma Diagnosed?

During your comprehensive eye exam, Dr. Weisz will check for glaucoma using specific tests, such as the following:

  • Side VisionThe side vision test, also known as the visual field test, measures your central and peripheral vision since an early sign of glaucoma is the loss of peripheral vision.
  • Tonometry: During a tonometry test, Dr. Weisz uses an instrument called a tonometer to measure any pressure in your eyeball. The pressure in your eyeball is a crucial sign of glaucoma.
  • Visual Acuity: During the visual acuity test, you’ll read a standard eye chart. Doing so allows Dr. Weisz to determine your scope of vision at different distances.
  • PachymetryPeople with thinner corneas — the transparent layer that forms the front of your eyes — are more likely to develop glaucoma. A corneal pachymetry test involves the use of a pachymeter, a medical device used to measure the thickness of your cornea.
  • Dilated Eye ExamDr. Weisz uses dilating eye drops to dilate your pupils and examine the back of your eyes to check for signs of optic nerve or retina damage.

Who is at Risk for Glaucoma?

Anyone can develop glaucoma, but people with thinner corneas are more at risk. Other people who have a higher risk of developing glaucoma include:

  • African-Americans over the age of 40
  • All adults over age 60
  • People with a family history of glaucoma
