OCT (Optical Coherence Tomography) is an advanced eye scan. Similar to ultrasound, OCT uses light rather than sound waves to image the different layers that make up the retina at the back of your eye. The OCT machine captures both a photograph and a cross-sectional scan of the eye at the same time.
The scan is non-invasive, quick, and painless. It a facilitates early detection of a number of common eye conditions, sometimes before you have even developed any symptoms, and the software can automatically detect even subtle changes in the retina with every eye test you have. This gives an invaluable ongoing record of the health of your eyes.
Common conditions identified through regular OCT screening include:
