Ocular Coherence Tomography (OCT)
Available in Edgware and Waltham Cross
Our Ocular Coherence Tomography (OCT) equipment provides the latest in state of the art opthalmic diagnosis.
The OCT records reflections from the various layers of the retina which are found at the back of the eye. Although very advanced in its technology the process of an OCT scan is very straightforward - you see a red flickering light as the OCT scan is taken.
Some of the conditions that the Ocular Coherence Tomography (OCT) scan can detect are:
A brief guide to OCT Tests
The OCT machine is a type of scanner. The result of this scan is data that helps your doctors to diagnose and manage your condition.
The OCT uses light waves to make a map of the retina at the back of your eye to show up any damaged areas. It uses an optical measurement known as low-coherence interferometry to scan across the retina and generate a cross-sectional image of your eye.
When you arrive, you will have eye drops put in your eye/s to make your pupils larger. This can take up 30 minutes to work.
The drops will cause your vision to become blurred. This lasts for 6-8 hours. It is important that you do not drive to your appointment or operate machinery during this time. The drops can also make your eyes sensitive to bright light; you may wish to bring a pair of sunglasses with you to protect your eyes.
Once your pupils have dilated, an imaging specialist will take you into the OCT room. 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.
