An optical coherence tomography scan (commonly referred to as an OCT scan) helps us to view the health of your eyes in greater detail. This allows us to see what’s going on beneath the surface of the eye and to detect any potential eye surface problems.
Imagine it 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 map out and measure the thickness of these layers to get an even clearer idea of your eye health and OCT scans can help detect sight-threatening eye conditions earlier. In fact, glaucoma can be detected up to four years earlier.
OCT is separate to an eye test. An eye test checks your eye health as well as how well you can see. Part of that often involves taking an image of the back of the eye (digital retinal photography), but an OCT scan takes this a step further, allowing your optician to look even deeper into your eyes and the structures within it.
Essentially, an it gives your optician a clearer idea of your eye health when testing your eyes.
Even if your vision and eye health are perfectly fine, we do still recommend an OCT scan with every eye test to identify any signs of determination.
OCT scanning is great at confirming that your eyes are healthy and can be repeated over time for comparison. This makes it particularly useful for detecting potentially sight threatening conditions that generally don’t have any symptoms until they start to have an impact on your vision.
Many of these conditions form at the very back of the eye,
• Diabetic retinopathy
• Detached retina
• Age-related macular degeneration
• Macular hole
