OCT – Edward Watts Opticians

What is OCT?

Optical Coherence Tomography is a non-invasive imaging test. OCT uses light waves to take cross-section pictures of your retina. With OCT, your optometrist can see each of the retina’s distinctive layers which allows them to map and measure their thickness. These measurements can help with diagnosis, such as glaucoma and macula degeneration.

This is an example of a fundus photograph. We carry this out with each examination currently at no charge.

This is an example of an OCT scan. It is more in-depth than a standard fundus photograph and not done as standard but it available upon request.

It will take about 10 minutes to complete the full exam. It is non-invasive and painless. You place your chin onto a chin a rest and keep your eyes open as you look at a little light within the machine. While you are looking at the little dot, the OCT machine will scan your eye.
