Tonometry

Glaucoma Screening Test

Why It Is Done

Tonometry may be done:

• As part of a regular eye examination to check for increased intraocular pressure (IOP), which increases your risk of glaucoma.
• To check the treatment for glaucoma. Tonometry can be used to see if medicine is keeping your IOP below a certain target pressure set by your doctor.
