What does borderline mean on a visual field test?
11. GHT borderline is displayed when the p value is between 1% and 3%. Generalized depression indicates that the most sensitive test points are less than 50% of normal. Abnormally high sensitivity is a red flag and indicates low reliability (usually associated with a high rate of positives).
What is open angle with borderline findings?
Open-angle suspects have one or more eye findings that suggest a higher risk of having or developing glaucoma than the average person. First, their measured eye pressure (IOP) can be higher than the average range. Glaucoma damage happens when the IOP is too high for the continued health of the optic nerve.
How does an ophthalmologist check your eyes?
Vision screening Your doctor will perform a visual acuity test. During this test, you’ll look at a chart containing symbols or shapes (such as the alphabet). The doctor will take note of your ability to correctly identify these symbols or shapes from a distance. They’ll also perform a refraction test.
How does an ophthalmologist check for visual field loss?
Electroretinography To check for visual field loss from certain retina conditions, your ophthalmologist may also use electroretinography. This test measures the electrical signals of light-sensitive cells in the retina called photoreceptors as well as other cells. To do this test, your eyes are dilated and you will also be given numbing eye drops.
What does an ophthalmologist do for a living?

When to pause the visual field test for glaucoma?
You may also pause the test if you feel you need to take a break for a moment. Because you are looking straight ahead during the test, your doctor can tell which lights you see outside of your central area of vision. Since glaucoma affects peripheral vision, this test helps show if there is vision loss outside of your central visual field.

What can an ophthalmologist do to lower your eye pressure?
Depending on your eye pressure, your ophthalmologist may decide not to start treatment right away. He or she will monitor pressure with regular testing instead. However, your ophthalmologist may decide that you need medicine to lower your intraocular pressure. Eyedrop medicine can lower eye pressure.
Can a person with ocular hypertension develop glaucoma?
