![]() Uniquely, the OCT software can analyse subsequent scans to detect signs of change that may be the indication of early eye disease. It provides a permanent, digital record of how your eyes look at a specific moment in time, providing a baseline for all future visits. The scan is like a slice through the cake so we can see the structure of the part of the eye we want to look at. The OCT allows us to see these layers. This is where the OCT scan is so useful. It allows us to look at the layers of the retina (the back of the eye) rather than just looking at the top of the retina – a bit like looking down onto a cake, we can see the icing but can’t see the layers inside the cake. This technology is a bit like the eye’s version of an MRI-scan or ultrasound, in that it provides a much more detailed, 3D assessment of the back of your eye. It is painless and harmless and takes seconds to perform. Early detection of eye disease allows for better protection of your vision.Īn example of an OCT scan showing the layers of the retina This is particularly relevant for glaucoma and macula degeneration. It allows us to detect signs of eye disease at a much earlier stage, often years before we can detect problems with more traditional methods of examination. An OCT scan provides additional peace of mind and reassurance that your eyes are as healthy as we think they are. We are sure you want to know that your eyes are healthy. It looks a bit like an ultrasound, but it uses red light to scan through. OCT stands for Optical Coherence Tomography and is a scan through the structure of the back of the eye.
