WHAT IS AN OCT SCAN?

OCT stands for Optical Coherence Tomography and is a scan that allows us to see beneath the surface of the eyes, so we can assess their health in greater detail.

The scan 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, getting a greater understanding of your eye health.

At M&S Opticians, we perform an OCT scan as part of every eye test. We keep the images on your record so we can track any changes that occur when you visit us again. 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 sound waves. It is completely painless and will only take a few moments so you don’t need to worry.

During the scan, you will be asked to place your 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.

 

WHO NEEDS AN OCT?

Even if your vision and eye health are perfectly fine, an OCT scan is always beneficial. We recommend taking an OCT if you are aged 25 or older. It will help keep track of your health and safeguard it. An OCT allows Opticians to identify eye conditions including

ARE THERE ANY OCT EYE TEST SIDE EFFECTS?

An OCT scan is a safe, non-invasive procedure that involves using reflected visible light from a low-power laser. Also, OCT machines have been designed to cease scanning the moment it detects too much light exposure. Therefore, there are no side effects or risks associated with the procedure.
