What Are Clinical Eye Tests?

Using specialist equipment, the Optometrist examines the interior and exterior of the patient's eye to check for any abnormalities that may require further investigation.

The Optometrist will use equipment to assess the following areas of the eye:

  • Eyelids
  • Lashes
  • Tear film
  • Conjunctival membrane
  • Cornea
  • Iris
  • Lens
  • Interior eye media
  • Retina
  • Optic nerve head
  • Retinal blood vessels
  • Macula

The Optometrist will be looking for a range of abnormalities that will determine whether or not the patient is developing an eye condition. For example, a clinical eye test is the best way of detecting early signs of glaucoma, which can cause partial and full loss of sight.

What Equipment is Used to Perform a Clinical Eye Test?

A clinical eye test uses a range of techniques to help determine the health of a patient's eye. As well as using manual techniques, the Optometrist will also use machinery to gain a broad understanding of eye health.

Retinal Imaging

Retinal photography involves taking images of the back of your eye through your pupil. These images can then be enlarged or enhanced to aid the optometrist in assessing your eye health. As the images are stored for the future it is easier to check for changes in the retina over time which could lead to earlier diagnosis of eye conditions. Depending on your age and the clarity of your eye's lens it may be useful to use eyedrops to enlarge your pupils to improve the clarity of the photographs. The drops usually take 20 minutes to take effect and the effects last for approximately 4 hours. You should not drive or operate machinery until the effects have worn off.
