OCT: Optical Coherence Tomography
What is an OCT scan?
Optical Coherence Tomography is an extremely advanced scan of the eye. It works in a similar way to ultrasound but uses light rather than sound waves. Light reflected from the front or the back of the eye, is used by the OCT to create a highly detailed picture in two or three dimensions. This can give your optometrist a view of your eyes on a microscopic level.
- Allows your optometrist to see beneath the surface of your eye, allowing them to view structures and sections that would be otherwise invisible
- A digital record of your eye is kept for comparison at your next exam, helping creating a timeline for you eye health
- OCT scanning can detect a number of key eye conditions earlier than previously possible, such as glaucoma, age-related macular degeneration (AMD) and diabetic eye changes
- OCT is suitable for all ages, including children
- Scans have made it easier than ever to find out the exact state and location of a particular eye condition
- Your optometrist can review images on screen and pinpoint areas of concern by digitally peeling back the layers until they define any areas requiring further investigation
Having an OCT scan is a quick and easy process. Nothing comes into contact with the eye and it is completely pain free. You will be asked to look at a target and the scan will be taken in less than a minute, much like taking a photograph.

As part of our commitment to excellence we offer OCT as part of your NHS funded eye exam. However, if you wish to have this service privately it will cost £30. We recommend taking an OCT scan as part of our enhanced eye exam.
