Optical Coherence Tomography


Optical Coherence Tomography (OCT)


We have recently invested in 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. It’s called a 3D Optical Coherence Tomography system (3D OCT)

What is OCT?
The OCT machine is a type of scanner. The result of this scan is data that helps your optician to diagnose and manage any potential conditions.

How does it work?
The OCT uses light waves to make a map of the retina at the back of your eye to show up any damaged area. It uses an optical measurement known as low-coherence interferometry to scan across the retina and generate a cross-sectional image of your eye.

What happens during OCT?
You will be seated in front of the OCT machine, you will then be required to place your head onto a support and to keep very still whilst the back of your eye is scanned. This is totally painless and takes around 10-15 minutes.

What happens to your results?
Your optician will study the results of your scan carefully before making a decision regarding any possible treatment options. The results may be discussed with you on the day, or you may be given a follow up appointment.

All of the above will be explained to you in more detail on the day of your appointment. You will also have an opportunity to ask any questions whilst you are here.

If you have any questions regarding the OCT scan or anything contained within this information, please contact a member of staff in any of our practices.
