Tonometer

 

Tonometry is a test to measure the pressure inside your eyes. The test is used to screen for glaucoma.

 

How the Test is Performed

 

There are many methods of testing for glaucoma.

The most accurate method measures the force needed to flatten an area of the cornea.

  • The surface of the eye is numbed with eye drops. A fine strip of paper stained with orange dye is held to the side of the eye. The dye stains the front of the eye to help with the exam.

  • The slit-lamp is placed in front of you. You will rest your chin and forehead on a support that keeps your head steady. The lamp is moved forward until the tip of the tonometer just touches the cornea.

  • Blue light is used so that the orange dye will glow green. The health care provider looks through the eyepiece on the slit-lamp and adjusts a dial on the machine to give the pressure reading.

  • There is no discomfort with the test.
