What is OCT?

OCT, which stands for Ocular Coherence Tomography, is an amazingly advanced piece of technology. Whilst digital eye photographs are only able to image the the surface of retina, or the back of the eye, an OCT scan allows us to instantly examine eye health throughout the whole depth of the retina. 


The OCT scanning machine uses light waves (in much the same way that an Ultrasound machine uses sound) to see under the retina and build up a composite, three-dimensional model of the back of the eye. The process is completely safe and painless, and nearly as quick as taking a photograph!

What can an OCT Scan detect?

In examining what lies beneath the surface of the retina, we are providing ourselves with a comprehensive insight into the health and function of the body’s vasculature, or blood vessels. As such, an OCT scan can aid in the pre-emptive detection of many diseases, which are as far ranging as glaucoma, macular degeneration, and oxidative stress.


Our state-of-the-art OCT scanning machine is a hospital-grade piece of medical equipment. When you elect to have an OCT scan, you know that you will be catching any of these degenerative conditions as early as possible and, as a result, minimising the impact they have on your body and well-being. 

Mehta Opticians has an OCT Scanning Machine in both their Welshpool and Newtown practices. If you're interested in finding our more about our OCT Scanning Machines, or would like to book an OCT Scan, get in touch today!
