Ocular Coherence Tomography (OCT)

Advanced, 3D scanning of your eyes.

What is OCT?

City Sight has a revolutionary piece of diagnostic equipment that can detect a number of common eye conditions, such as glaucoma, age related macular degeneration (AMD) and diabetic retinopathy, during a routine eye test.

This piece of equipment is called a 3D Optical Coherence Tomography system (3D OCT) and is manufactured by the world leading optical equipment manufacturer Topcon.

How does an OCT scan work?

Ocular Coherence Tomography is an advanced eye scan for people of all ages. Similar to ultrasound, OCT uses light rather than sound waves to reveal the many layers that make up the back of the eye.

This particular 3D OCT unit captures a digital photograph of the inner surface of the eye at the same time, so that areas of concern identified by the scan can be cross referenced with the classic view of the back of the eye that your optometrist sees.

With this unique, non-invasive technology, your optometrist is able to see both the surface of the back of your eye and a three-dimensional image of the layers that are beneath it.

Your optometrist can then review the images and more confidently diagnose, manage or refer you to an eye doctor for further treatment, should this be required. For the majority of patients, OCT provides significant reassurance that the deeper layers of their eye are healthy.
