What is an OCT scan?
An optical coherence tomography scan (commonly referred to as an OCT scan) helps us to view the health of your eyes in greater detail, by allowing us to see what’s going on beneath the surface of the eye.
Imagine your retina like a cake – we can see the top of the cake and the icing using the 2D digital retinal photography (fundus camera), but the 3D image produced from an OCT scan slices the cake in half and turns it on its side so we can see all the layers inside.
Our opticians can then examine these deeper layers to get an even clearer idea of your eye health.
OCT scans can help detect sight-threatening eye conditions earlier. In fact, glaucoma can be detected up to four years earlier than traditional imaging methods.
