Intraocular pressure (IOP) is the only modifiable risk factor for glaucoma progression. This review details various tonometry instruments used to measure IOP, aiding clinical decisions.

Area of Science:

  • Ophthalmology
  • Medical Devices
  • Glaucoma Research

Background:

  • Glaucoma development and progression are influenced by multiple factors.
  • Intraocular pressure (IOP) is the sole modifiable risk factor for glaucoma.
  • Reducing IOP is crucial for managing glaucoma progression through medical and surgical interventions.

Purpose of the Study:

  • To review commonly available tonometry instruments for measuring intraocular pressure (IOP).
  • To discuss the advantages, disadvantages, and clinical applicability of different tonometers.
  • To aid ophthalmologists in selecting appropriate tonometry devices for patient care.

Main Methods:

  • Review of current literature on tonometry devices.
  • Description of established and novel tonometry technologies.
