By Dr. David Masihdas on December 05, 2020

Because early symptoms can be difficult to detect, glaucoma should be checked for regularly, especially if you are part of an at-risk group.

At Utah Eye Associates in Salt Lake City, UT, we are on your side in the fight against glaucoma. Our doctors will discuss the types of glaucoma testing we provide.

When to Check for Glaucoma

While glaucoma can occur in younger people, it typically develops in adults over the age of 60. However, we recommend coming in for a general eye exam at age 40. Glaucoma can sometimes be present without visible symptoms, so it is important to get checked regardless of your current vision quality.

Symptoms of Glaucoma

There are two main types of glaucoma, open angle and acute angle-closure.

Symptoms of open angle glaucoma include:

  • Loss of peripheral vision in the early stages
  • Tunnel vision in the later stages

Acute angle-closure glaucoma is a more serious condition that must be treated immediately. Possible symptoms include:

  • Intense eye pain
  • Nausea accompanying pain
  • Redness in eyes
  • Blurry vision
  • Seeing halos around lights

Types of Glaucoma Tests

Our Salt Lake City eye center proudly offers the following exams. Take charge of your eye health by scheduling an appointment with us. We will determine which tests may be needed, as well as possible treatment options.


As the “peri” in the name suggests, perimetry tests your field of vision, often looking for diminished peripheral vision that indicates early glaucoma. During the test, your optometrist will ask you to look straight ahead while they shine a light in your peripheral vision.


This tests the pressure in your eye. For a tonometry test, your optometrist will administer numbing eye drops. You will rest your head and face on a special type of microscope called a slit lamp. Using a small puff of air, a tonometer is used to measure your eye’s inner pressure.


A pachymetry test measures the thickness of your cornea, the transparent barrier of the front of the eye. Your cornea protects the lens and is vital to proper eye function. A pachymeter is placed on the front of your cornea, measuring its thickness. Corneal thickness can affect eye pressure readings, so it is important to take this test to confirm a tonometry test.

Eye Dilation

For this test, eye drops are administered to dilate your eyes. Your optometrist will then use a light and magnifying device to examine your optic nerve.


This exam can determine if you have acute-closure or open-angle glaucoma. Your eyes will first be numbed with eye drops. Next, a special contact lens with a mirror is placed on your eye. Your optometrist can then determine the angle between the iris and cornea.

Optic Nerve Photography

In addition to the previously mentioned tests, optic nerve photography is effective at catching signs of glaucoma. Using either a camera lens or a laser scan, a high-definition picture is taken of your eye. This picture allows our optometrists to examine the optic nerve in detail. From this, we can determine if there is any damage to be concerned about.
