OCT scans explained

Optometry is a rapidly evolving field with technological advances continually improving how optometrists examine the eyes and diagnose and treat eye conditions.

One such technology is OCT scans – a powerful 3D imaging tool that allows a detailed insight into the eyes to help detect any eye health problems at their very early stages.

What is an OCT scan?

An OCT scan (Ocular Coherence Tomography) uses a powerful state-of-the-art camera to scan the eyes and provide a highly detailed 3D picture of the eye.

OCT scans enable a comprehensive examination of the eyes which can help in the diagnosis, early intervention, and treatment of eye-related conditions many years before they would be detected by traditional optometry tests.

An OCT scan uses light waves to produce 3D images of the eyes allowing your optometrist to see up to 80% of your eye from all angles. The cross-sectional images provided by an OCT scan show the layers making up the retina and the structure of the eye beneath the surface.

An OCT scan is non-invasive, painless, and takes just a few minutes. If you are visiting Optomeyes for an OCT scan, we allow an additional 30 minutes for your appointment so you can feel relaxed and take the time you and your optician need to thoroughly answer any questions or concerns you may have.

What do opticians see during an OCT scan?

A standard eye test might involve an examination of the surface and back of the eye, but an OCT scan goes much further than this allowing the optometrist to see the layers making up the inside of the eye and the retina at the back of the eye.

The 3D image created by the OCT scan is made up of hundreds of images the scanner takes of the eye that are up to 25 times better resolution than any other imaging technology. These images are then put together to generate the full 3D picture and analysed by the optometrist for any sign of potential problems. Even if the OCT scan shows no problems, it provides a useful baseline to go on record and refer to in any future tests.

What can an OCT scan detect?

The images provided by an OCT scan can help optometrists to spot signs of eye conditions such as macular degeneration, glaucoma, macular holes, diabetic retinopathy, and other retinal abnormalities. Such eye conditions often don’t have visible symptoms until they’re quite advanced.

It is the early detection that makes OCT scans so advantageous – an OCT scan can detect conditions such as glaucoma up to four years earlier than other optometry tests. The earlier eye and health conditions are diagnosed, the more effective treatment is likely to be before they become much more serious or sight-threatening.

When to have an OCT scan

An OCT scan can be useful at any time but especially if you are over 40, you have any concerns about your eyes, or have a family history of eye disease.
