Why it’s important: Glaucoma is a condition which can cause incurable blindness. If it’s detected in its early stages, it’s possible to slow its progression. Individuals are not aware of vision loss until the late stages of the condition.
How often: Basic glaucoma tests are performed during routine eye checks, but if your optometrist determines you are at higher risk for glaucoma, they may ask you to return more frequently for additional glaucoma tests.
What’s involved: Glaucoma cannot be diagnosed by one test alone. Your optometrist may test your eye pressures and look at the nerves in the back of your eyes. They may also test your peripheral vision (visual fields), the ‘drainage system’ of your eyes, and they may refer you to an eye specialist for further tests.
How long will it take: most glaucoma tests can be performed during a routine consultation. If your optometrist requests a peripheral vision check, these appointments take up to 30 minutes to complete and may need to be repeated.
