Optical Coherence Tomography (OCT)
Our download section contains a comprehensive information sheet on the OCT click here.
This highly useful technology is normally seen only in top eye hospitals such as Moorfields. You can now benefit from significantly improved diagnostic technigues that can spot dangerous eye conditions up to 4 years sooner than previously possible.
The Optical Coherence Tomographer (OCT) allows us to take 3-dimensional scans of the back and front of your eyes, rather like an MRI scanner does for the rest of the body. The procedure is comfortable and the image captured in seconds using optical scanning and flash photography – nothing touches your eyes.
The images show exceptional detail and show changes that are too small to be seen by the eye. The tomographer allows you to be aware of changes in your eyes before any symptoms appear, giving you advanced warning and early intervention.
What are the Benefits?
A permanent and extremely accurate record can be kept of the condition of your eyes.
Detection of changes too small to be seen even using Retinal Photography can be picked up and compared year on year against previous 3D scans.
Allows you to see what we see and to understand any changes taking place.
Allows precise diagnostic levels of detail ensuring timely, accurate referral to a consultant surgeon should that be necessary.
Who should have OCT?
Everyone who wants the best available eye care but particularly:
- All those over 40.
- Family history of eye problems.
- Diabetics even if already in a screening service.
- General health problems that may affect the eyes.
- Anyone who has an abnormality detected using any other method.
How is this an Improvement over Retinal Photography?
The OCT takes a 3D scan of the eye so we can look through the surface at the cross section of layers below, which we have never been able to see before now, and magnify them to ensure that they are as they should be. A retinal photograph is also taken at the same time which is of a higher quality than a normal retinal image. We can measure and therefore monitor the thickness of all the key layers within the back of the eye so that we can pick up changes in thickness even when they look normal.
