What tests are used to detect Glaucoma?

Glaucoma is one of the leading causes of irreversible blindness. Early detection is essential to limit the damage to the optic nerve and best preserve the vision.

Glaucoma in no longer defined by eye pressure alone. Various tests are done in order to accurately diagnose glaucoma:

  • The pressure of the eye (tonometry)
  • The appearance of the optic nerve (fundus photography)
  • The scan of the nerve fibre layer of the optic nerve (OCT – optical coherence topography)
  • The field of vision (perimetry)
  • The drainage area of the eye (gonioscopy)
  • The thickness of the cornea (pachymetry)
