What is Glaucoma?
First, it’s important to understand what exactly glaucoma is. Once you understand this disease, you will have a better understanding of its symptoms and when to visit an eye doctor about glaucoma-related questions. Glaucoma is the leading cause of irreversible blindness in the world today. Glaucoma is a group of diseases that damage the eye’s optic nerve and can result in vision loss and ultimately, if left untreated, blindness. However, with early detection and treatment, you can often protect your eyes against any serious glaucoma-related vision loss. Glaucoma usually has no initial symptoms and therefore can only be diagnosed through regular eye exams by your eye doctor.
What Causes Glaucoma?
Glaucoma is caused by the build-up of high fluid pressure inside your eye. The liquid in the front part of the eye may not circulate normally. There are mesh-like channels that can become blocked allowing liquid to build up. This condition is commonly hereditary and therefore can be passed from parents to children.
Who Should be Checked for Glaucoma?
If you’re over age 40 and have a family history of glaucoma, you should get a complete eye exam from an eye doctor every 1 to 2 years. If you have health problems like diabetes or a family history of glaucoma or are at risk for other eye diseases, you may need to go more often. Because glaucoma’s symptoms can be hard to detect initially, it is important to visit your Tempe, AZ area eye doctor for a complete glaucoma test.
Without treatment, people with glaucoma will slowly lose their peripheral (side) vision. As glaucoma remains untreated, people may miss objects to the side and out of the corner of their eye. They seem to be looking through a tunnel. Over time, straight-ahead (central) vision may decrease until no vision remains.
How do you Test for Glaucoma?
Glaucoma is detected through a comprehensive dilated eye exam that includes the following:
- Visual acuity test. This eye chart test measures how well you see at various distances.
- Visual field test. This test measures your peripheral (side vision). It helps your eye care professional tell if you have lost peripheral vision, a sign of glaucoma.
- Dilated eye exam. In this exam, drops are placed in your eyes to widen, or dilate, the pupils. Your eye care professional uses a special magnifying lens to examine your retina and optic nerve for signs of damage and other eye problems. After the exam, your close-up vision may remain blurred for several hours.
- Tonometry is the measurement of pressure inside the eye by using an instrument called a tonometer. Numbing drops may be applied to your eye for this test. A tonometer measures pressure inside the eye to detect glaucoma.
- Pachymetry is the measurement of the thickness of your cornea. Your eye care professional applies a numbing drop to your eye and uses an ultrasonic wave instrument to measure the thickness of your cornea.
- GDx or glaucoma diagnosis scans the retina and creates a detailed map of retinal nerve fiber thickness. This test can be done quickly and does not require pupil dilation. This test can aid in identifying the severity of glaucoma in a patient as well as measuring progression of glaucoma over time.
