Ocular Coherence Tomography Screening

What is OCT? 


OCT - Ocular Coherence Tomography - is an advanced eye scan for people of all ages. similar to ultrasound, OCT uses light rather than sounds waves to illustrate the different layers that make up the back of the eye. the OCT machine captures both a fundus photograph and a cross-sectional scan of the back of the eye at the same time.


What does OCT cost? 


There is an additional charge for the OCT scan, but the benefits are obvious. So you can enjoy the peace of mind that comes from knowing that your eyes are in great condition.


The scientific stuff!


Using a Topcon state of the art 3D OCT camera, your optometrist will take both a digital photograph and a three dimensional cross sectional scan of the back of the eye in one sitting. this allows us to instantly diagnose a number of common conditions. the scan is non-invasive, painless, simple and quick.

What's more, the software can automatically detect even the most subtle changes to the retina with every eye test you take. This gives you an invaluable ongoing record of the health and condition of your eyes.

What is OCT Scanning?

This video below demonstrates the technology.

What can the scan check for?

Common conditions identified through regular OCT screening include:



Diabetic retinopathy is a major cause of visual impairment amoung adults. Here in the UK, more than two million people have been identified as having diabetes.

OCT examination enables early detection, which greatly improves the sucess of treatment


Age-related macular degeneration

Macular degeneration causes the gradual breakdown of the macular (the central portion of the eye). OCT cannot only identify this condition and its type (there are two types, wet and dry) but also monitor its progress, for example if you are ungoing treatment for such a condition. Unfortunately the risk of developing macular degeneration increases with age, and it is the common cause of vision loss in individuals over the age fifty.



Glaucoma damages the optic nerve at the point where it leaves the eye. recent statistics suggests that some form of glaucoma affects around two in every 100 people over the age of 40. The danger with chronic glaucoma is that there is no pain and your eyesight will seem to be unchanged, but your vision is being damaged. An OCT examination will confirm if you are at risk, or indeed what stage of glaucoma you may have.


Macular Holes

A macular hole is a small hole in the macular - the part of the retina which is responsible for our sharp, detailed, central vision. This is the vision we use when are looking directly at things, when we are reading sewing or using the computer.. There are many causes of macular holes. One is caused by vitreous detachment, when the vitreous pulls away from the back of the eye and sometimes it does not 'let go' and eventullay tears the retina, leaving a hole. Extreme exposure to sunlight (for example staring at the sun during an eclipse) can also cause a macular hole to develop.


Vitreous Detachments

Vitreomacular traction can clearly be diagnosed through OCT providing invaluable information about the current relationship between the vitreous and the retinal surface of the eye. As people get older the vitreous jelly taht takes up the space in our eyeball can change. It becomes less firm and can move away from the back of the eye towards the centre, in some cases parts do not detach and cause 'pulling' of the retinal surface. Th danger of a vitreous detachment is that there is no pain and your eyesight will seem unchanged but the back of your eye may be being damaged.
