What is a Tonometry test?

  • Our eyes are filed with various types of fluid that bathes and nourishes the eye and drains out of the chambers with new fluid being formed.
  • In some cases, the fluid drains too slowly, causing pressure build-up.
  • Tonometry uses a device called tonometer to measure the pressure inside the eye.
  • This pressure is actually the ratio between the amount of aqueous humour produced in the eye and the ease with which it leaves the eye.
