OCT

Optical coherence tomography (OCT) is an advanced diagnostic scan that uses laser light to help our optometrists view cross-sectional images of the various layers of your retina at the back of your eye.

The OCT scan helps us to view and measure the thickness of the different layers of tissue that make up your retina, to give us a better evaluation of the health at the back of your eye. It’s through this non-invasive process that our optometrists can most accurately detect any changes and early signs of eye diseases and sight-threatening conditions.

The OCT scan is part of our enhanced eye examination, which takes a minimum of 40 minutes.

What happens during an OCT scan?

We use a state-of-the-art OCT device called the Topcon Maestro. This advanced technology helps us to painlessly assess your eyes with unparalleled accuracy in just 50 seconds.

To get a better view of your retina, your optometrist may begin by dilating your eyes to make your pupils bigger. You’ll be asked to sit in front of the OCT machine and keep your head as still as possible. As you look into a viewfinder, your eyes will be quickly scanned by a camera, capturing each layer of the retina. These images are then put together to form an overall picture of the back of your eye. Please note that if pupil dilation is needed, your eyes may be sensitive to light after the scan is complete.

Benefits of OCT

We recommend OCT scans for everyone, even if your vision and eye health seem fine. If you have a family history of eye diseases such as glaucoma or diabetes, OCT scans are especially important. They allow your optometrist to monitor even the most minute changes in your eyes, helping with early diagnosis of eye conditions.

Some of the eye conditions that an OCT scan can help diagnose include:

  • Glaucoma
  • Macular degeneration
  • Diabetic retinal disease

This diagnosis is especially useful for us as it allows us to refer our patients to an ophthalmologist for further examinations or treatment if necessary.

The results of an OCT scan are instantaneous, meaning your optometrist can assess them straight away and also explain their findings to you for your peace of mind. The scan images will be saved in your patient record so we can build up a chronological history after every visit and monitor all changes to the back of your eye.
