Tonometry

Pressure in the eye is called intraocular pressure (IOP). Tonometry tests the amount of pressure in the eye.

  • Call Your Doctor

    After the test, call your doctor if you have any of the following eye discomforts:

    • Burning
    • Excessive itching
    • Swelling
    • Pink or reddish color that does not go away
    • Decreased vision
    • Any other eye problem

    In case of an emergency, call for medical help right away.

  • Definition

    Pressure in the eye is called intraocular pressure (IOP). Tonometry tests the amount of pressure in the eye.

  • What to Expect

    There are two main types of tonometry: the
    non-contact air puff method
    and the
    applanation method that flattens the cornea with pressure. The type of tonometry that is done will depend on the equipment your doctor has and the type of test they decide to do.

  • Reasons for Test

    Elevated eye pressure can lead to eye damage. This may be part of a disease called
    glaucoma.
    If left untreated, glaucoma can cause blindness. Tonometry is used to screen for glaucoma. It is also used to monitor the treatment of glaucoma.

    You may have ocular hypertension. This happens when pressure is elevated but is not caused by glaucoma.
