Stages and Tests for Glaucoma
In my last article, we discussed some of the key things to know about glaucoma; now we will discuss the stages and tests for glaucoma.
Why is primary open angle glaucoma a "multi-factorial" disease?
Glaucoma is a disease where the nerve tissue (neurons) connecting the eye to the brain are lost. For the first 200 years since its discovery in the 1800's, glaucoma was thought to be a disease caused by high pressure inside of the eye. However, it has been since realized that this is only one piece of the puzzle. We now perform many different tests for glaucoma, and you can read about each below.
Glaucoma: Tests, Signs, and Symptoms
Eye Pressure - Sign of Risk
Corneal Thickness - Sign of Risk
Family History - Sign of Risk
Angle Closure (Gonioscopy) - Sign of Acute glaucoma
Optical Coherence Tomography (OCT) - Sign of Early Glaucoma
Optic Nerve "Cupping" - Sign of Early, Moderate, and Late Glaucoma
Visual Fields - Sign of Severe Glaucoma
Vision Loss - Symptom of End-stage Glaucoma
What You Need to Know
Sometimes all the tests can become overwhelming. The most important things to remember about primary open-angle glaucoma is that it is a very slow progressing disease and preventative treatment is extremely successful for almost all patients. However, you will not notice your glaucoma, there are no signs until the last 5% of tissue loss, and by that time it is too late to return you to being fully sighted- so it is extremely important for glaucoma suspects to attend regular checkups with an eye care professional.
