Although this article focuses on diagnosing glaucoma, it is worth noting that presently, a cure for the condition does not exist.

Loss of vision caused by glaucoma can progress so gradually that most cases are not even found until the disease has reached an advanced stage.

Because of the sneaky and dangerous nature of this disease, it is crucial for individuals to recognize its symptoms and seek an early diagnosis.

Schedule regular eye exams and ask your doctor to measure your intraocular pressure.

To look for or diagnose glaucoma, the following tools will be used by your optometrist:
  • The tonometry test: this test measures intraocular pressure (IOP) by observing the cornea’s resistance to pressure. Results determine whether medication can effectively reduce intraocular pressure to an appropriate level.
  •  Normal IOP falls between 10 and 21 mmHg
  •  Abnormal IOP exceeds 21 mmHg
  • An ophthalmoscope allows a doctor to see increased intraocular pressure in the eye.
  • • A visual field test will check for blind areas in your vision caused by high pressure.
  • A pachymeter is used to measure the thickness of the cornea. Test results can detect hidden cases of Glaucoma.
  •  Any optic nerve damage, which can be a sign of glaucoma, can be detected by looking directly through the pupil to the back of the eye.
A combination of tests is necessary before a patient can be diagnosed with glaucoma. The most common signs of the disease are areas of blurred vision, increased intraocular pressure, optic nerve damage, and loss of vision.
