OCT explained

OCT explained

OCT stands for Optical Coherence Tomography and is a scan that allows us to see beneath the surface of the eye. It produces a 3D image of the retina at the back of the eye and the different layers within it. We can then measure the thickness of these layers to get a greater understanding of your eye health.

We will do an OCT scan as part of every eye test. We will keep the images on your record so we can track any changes that occur when you come back and visit us. In particular, it can help our Optometrists detect any underlying eye health conditions such as glaucoma, diabetic retinopathy and age-related macular degeneration much earlier than we would have been able to previously.

How does an OCT scan work?

An OCT scan uses light waves to build up a 3D image of the eye, in much the same way that an ultrasound scan uses soundwaves.

You will be asked to place you head on a chin rest in front of the OCT scanner. It will scan both your eyes and there will be a flash of light as it takes the images. It is completely painless and will only take a few moments.
