Screening for Glaucoma

Screening is done to find a problem and treat it early. Tests are given to people who do not have symptoms but who may be at high risk for glaucoma.

Screening Guidelines

Glaucoma screening is done as part of a routine eye exam. A person should have an eye exam by age 40 and additional eye exams:

  • Every 2 to 4 years between the ages of 40 and 54
  • Every 1 to 3 years between the ages of 55 and 64
  • Every 1 to 2 years at age 65 and over

A tonometry test will be done to measure pressure inside the eye. A puff of air may be blown onto the cornea to take the reading. Or a small plastic device may be pushed against the eye to measure it.
