What is OCT?

OCT explained

Many common eye diseases don’t cause symptoms until they have progressed quite significantly, which means that your eye health may be changing without you experiencing any kind of difference in your vision.

That’s why we add an advanced 3D eye scan (OCT) to every eye exam to make sure changes to your eye health are spotted as early as possible.

OCT scans work by taking a series of scans of the back of the eye that form a detailed 3D image of important structures in your eye, such as the optic nerve, retina and macula.

These 3D scans help optometrists to spot any abnormalities and identify eye diseases, such as age‑related macular degeneration, glaucoma and diabetic eye disease, in their earliest stages.

These detailed 3D scans are also a useful tool in closely monitoring your eye health over time. This is particularly important if you have risk factors for eye conditions, or a history of eye disease in your family.
