Glaucoma Screening


If you are younger than 40 and have no known risk factors for glaucoma, the Canadian Ophthalmological Society (COS) recommends that you have a complete eye examination at least every 10 years. This includes tests that check for glaucoma.footnote 1 The COS suggests more frequent routine eye examinations as you age.

The COS also suggests that people who are at risk for glaucoma have complete eye examinations according to the schedule below:

  • Ages 40 to 49, at least every 3 years
  • Ages 50 to 59, at least every 2 years
  • Age 60 and older, at least once a year

Your eye doctor may advise you to have eye examinations more often, depending on your level of risk and your overall eye health.

People at increased risk for glaucoma include those who:footnote 2

Because people with glaucoma may have normal pressures in their eyes, measuring eye pressure (tonometry) should not be used as the only test for glaucoma. It needs to be combined with other tests before glaucoma can be diagnosed.

After reviewing all of the research, the Canadian Task Force on the Periodic Health Examination (CTFPHE) has not recommended for or against routine glaucoma screening for all adults.
