Tonometry
Informed by recognized medical guidance
Overview
Tonometry is a quick, painless test that measures the pressure inside your eye. This pressure is called intraocular pressure (IOP). High eye pressure can damage the optic nerve and lead to vision loss, so tonometry is an important test for checking eye health.
Key facts
- Tonometry is often part of a routine eye examination.
- The test helps detect and monitor glaucoma, a condition that can cause blindness if untreated.
- Most people feel only a slight puff of air or a gentle touch on the eye — it does not hurt.
Yes, tonometry is a common and routine test in eye care. It is used in many eye exams, especially for adults over 40 or those with risk factors for glaucoma.
Tonometry is performed on people of all ages, but it is especially important for older adults, people with a family history of glaucoma, those with high blood pressure or diabetes, and anyone with eye symptoms or vision changes.
