Optical Coherence Tomography, more commonly known as OCT is an advanced technology used to examine all parts of the eye, from the cornea (front optical surface) and anterior segment all the way through to the layers of the retina and optic nerve. It is particularly useful for examining the retina and optic nerve, especially in cases of suspect macular degeneration and glaucoma.
An OCT scan is comparable to a MRI or CAT scan for the eyes and can form a three dimensional image allowing your optometrist to see, sometimes for the first time, problems within your eye that could not easily be seen before.
As recently as 10 years ago OCT technology was mainly used in research laboratories, but recent advances in this revolutionary technology have brought it to the forefront of quality eye care. It is now available in certain hospitals with specialised eye departments but in only a few private consulting rooms such as ours.
What happens when I have an OCT scan?
The scan is very simple, can take just a few minutes to complete, is non-contact and simply involves looking into a camera lens. Our optometrists have been trained to assess the results of the scan (which are usually available immediately) and should the results show any anomalies, these can be measured and later reassessed if necessary.
What are the benefits of OCT?
The retina and optic nerve can be damaged by many common eye diseases like Glaucoma, Diabetes and Age Related Macular Degeneration. Using OCT our optometrists can detect anomalies at a much earlier stage, usually allowing better treatment options and improved visual outcomes.
Your optometrist may recommend an OCT scan to you following an eye examination or you may feel that you wish to benefit from the technology as a routine measure. The scan is not covered by the NHS but you are able to book a private appointment by speaking to one of our receptionists.
