What is OCT?

Ocular Coherence Tomography is an advanced eye scan for people of all ages.


Similar to ultrasound, OCT uses light rather than sound waves to illustrate the different layers that make up the back of the eye.


Our particular 3D OCT unit captures a digital photograph of the surface of the eye at the same time and this can be cross-referenced across any areas of concern.

The Benefits of OCT

The major benefit of this state of the art machine is that it allows your optometrist to see both the back of your eye, and a three-dimensional image to look beneath the surface of the regular retinal image. Never before, has it been easier to find out the exact state and location of a particular eye condition. Your optometrist can review the images on a PC screen and pinpoint areas of concern by digitally peeling the layers back until they define what it is that they have identified as requiring further investigation.

Using previous scan results, it is possible for our optometrists to spot tiny changes and early signs of various conditions, often before you even have started to experience any symptoms.

OCT Scanning at Adlam & Coomber

At Adlam & Coomber, we are proud to offer the state-of-the-art Topcon 3D OCT 2000 with an integrated fundus camera. This machine allows us to see the eye in greater detail and, in turn, get a clearer picture of your eye's health.

If you receive an OCT scan in addition to your typical appointment, you will take a seat in front of our OCT machine and rest your chin onto the machine's support to steady your head. To collect the images of your eye, the machine will then scan your eye, taking more than 1,000 images of your retina, without touching it. The scanning process only takes a few minutes. 

Please note that you may be given eye drops to beforehand to dilate your pupils. Your Optometrist will advise further if this applies to you.
