Ocular Coherence Tomography (OCT)

OCT is a new, completely painless and highly advanced screening that checks for potentially serious conditions such as glaucoma, diabetes, age-related macular degeneration, vitreous detachments and more.

What is OCT?

OCT is an advanced eye scan for people of all ages. Similar to ultrasound, OCT uses light rather than sound waves to illustrate the different layers that make up the back of your eye. The OCT machine captures both a funds photograph and a 3D cross-sectional scan of the back of the eye.

What does OCT cost?

There is an additional charge of £25 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.

How it works?

Using a Topcon state-of-the-art 3D OCT camera, our optometrist will take both a digital photograph and a tree dimensional cross sectional scan of the back of your eye in one sitting. This allows us to instantly diagnose a number of common conditions. The scans is non-invasive, painless, simple and 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 can the scan check for?

Common conditions identified through regular OCT screening include:

1. Glaucoma

Glaucoma causes damage to the optic nerve and can result in loss of vision. Statistics suggest that 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 may seem to be unchanged, but your vision is being damaged. Regular OCT scans of your optic nerve an pick up the earliest signs of optic nerve damage.

2. Age-related macular degeneration

Macular degeneration causes the gradual breakdown of the macula (the central portion of the retina). OCT cannot only identify this condition and its type (there are two types, wet and dry) but also monitor its progress. The risk of developing macular degeneration increases with age, and it is the most common cause of vision loss in individuals over the age of fifty.

3. Diabetes

Diabetic retinopathy is a major cause of visual impairment among adults. Here in the UK, more than two million people have been diagnosed with diabetes. OCT examination enables early detection, which greatly improves the success rate of treatment.

4. Macular holes & Vitreous detachments

A macular hole is a small hole in the retina which is responsible for our sharp, detailed, central vision. There are many causes of macular holes. one is vitreous detachment. Vitreous detachment occurs when the virtuous pulls away from the back of the eye. Vitreomacular traction a common cause of macular holes, can be diagnosed through OCT. As people get older the vitreous jelly that 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. The danger of vitreous detachment is that there is no pain and your eyesight will seem unchanged but the back of your eye may be damaged.
