Tonometry Test

A tonometry test measures the pressure inside a patient’s eye, known as intraocular pressure or IOP. By measuring the build-up of pressure, our optometrists can determine whether the patient is at risk of being diagnosed with Glaucoma.

How does a tonometry test work?

The most common type of tonometry test is called the “Goldmann Applanation Tonometry test”. This test works by firstly numbing a patient’s eye using eye drops. Once the eye is numb, the optometrist touches the eye with a tiny strip of paper containing an orange dye.

The purpose of the dye is to increase the accuracy of the test. The optometrist then places a machine called a “slit-lamp” in front of the patient, which is then moved toward the patient’s eye until just the tip of the tonometer probe touches the cornea. Once the tonometer probe touches the cornea, it slightly flattens it to detect the pressure within the eye.

Why do I need a tonometry test?

It is recommended that anyone over the age of 40 should consider a tonometry test to prevent Glaucoma, and provide an early diagnosis and treatment for the condition. An individual has increased ricks of being diagnosed with Glaucoma if they are:

  • Over the age of 60
  • Have a hereditary disposition to Glaucoma
  • Have Diabetes
  • Have Hypothyroidism
  • Are nearsighted
  • Have other chronic eye conditions
  • Have used corticosteroid medications for a prolonged period of time

It is crucial patient undertake a tonometry test if they have any of the above factors as Glaucoma can go undetected for several years. Without appropriate treatment, the pressure within the eye can harm the optic nerve and cause a loss of vision and potential blindness.

Auto Refraction

An Auto Refraction Test is designed to provide insight into a patient’s vision and whether prescription glasses or contacts will be required.

How does an auto refraction test work?

An Auto Refraction Test utilises a machine that measures the amount of light reflected by the patient’s retina. The procedure consists of a series of lens being shown to the patient to determine which one allows them to see clearly. The results allow the optometrist to conclude whether the patient is nearsighted, farsighted, or affected by astigmatism.

Both adults and children over the ages of three should undertake an Auto Refraction Test once every two or three eyes. It is crucial to have regular eye examinations using the Auto Refraction Test to measure any changes within the patient’s prescription lens and make the necessary modifications.
