OCT 3D scans are the most advanced eye screening tool currently available. If you are interested in booking an OCT scan, or you simply want to know more, you’ll find everything you need to know here.

What is an OCT scan?

OCT (Optical Coherence Tomography) is our most advanced,  scan that gives our optometrists a 3D image of the internal structures of the eye. It allows for each individual layer of the retina to be imaged to the point that their thickness can be measured.

What is the difference between traditional viewing of the retina during an eye test and an OCT scan?

Traditional viewing of the back of the eye allows us to only view the surface layers of the retina at the back of the eye. An OCT 3D scan give us images of the 10 layers of the retina therefore providing  considerably more information than a traditional viewing.

How does an OCT scan work?

This technology utilises waves of light to capture images of the retina (similar to how an ultrasound uses sound waves). You will be asked as a to sit in front of the machine and look at a target, the machine will then scan your eye in a few seconds. This scan is then analysed by a professional optometrist.

Is an OCT scan safe?

Absolutely, an OCT scan is perfectly safe and painless. Taking the scan is a very quick procedure with no side effects.

Who should have an OCT scan?

We recommend that anyone over the age of 18 book an OCT Scan. This is a great way to monitor our patients’ eye health and any changes over time, allowing early detection of various eye conditions. We also recommend an OCT scan to patients with certain conditions such as diabetes and also if you have a family history of Glaucoma or other genetic eye problems.

OCT scans can help to detect dangerous and sight-threatening eye conditions earlier than any other scan or traditional viewing method. Even if your eyes are healthy, an OCT scan is beneficial for your future eyecare, as we are able to make track your eye health and condition over time and monitor changes. Allowing us to detect potential eye conditions earlier and refer you on for future treatment.
