Looking after your eyes Since 1902

OCT

Here at Cooper and Leatherbarrow, we believe your vision is precious and we know that regular clinical eye examinations can help maintain eye health.

Many of our Optometrists undertake specialist training in using and analysing OCT (Optical Coherence Tomography) equipment. We have had an OCT since 2011, so the wealth of experience from using this equipment in practice ensures that you receive the very best treatment and advice.

Our staff have both the knowledge and experience to confidently operate the complex 3D Optical Coherence Technology, not only are they able to give you the best possible clinical experience but our Optometrists also have the depth of knowledge to analyse and fully understand the results of your examination.

What is OCT?

Ocular Coherence Tomography 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 the eye.  This state of the art machine allows your optometrist to see both the back of your eye, and a three dimensional image to look beneath the surface of the retina. Never before, has it been easier to find out the exact state and location of a particular eye condition. Your optometrist can review the images on a PC screen and pin point areas of concern by digitally peeling the layers back until they define what it is that they have identified as requiring further investigation.

Using this machine, we can confidently diagnose, manage and refer you to a specialist for further treatment, should this be required. At Cooper and Leatherbarrow, we can include this state of the art diagnostic tool as part of your eye examination. There is an additional charge for the OCT scan, but the benefits are obvious. The software can automatically detect even subtle changes in the retina meaning that over time we can build up a picture of not just your eye health today, but how your eyes are changing over time. This gives an invaluable on- going record of the health and condition of your eyes.

Make sure that when booking your next eye examination, you ask about an OCT scan.

SEEING BENEATH THE SURFACE IS ESSENTIAL TO THE HEALTH OF YOUR EYES

3D OCT screening diagnoses potentially serious conditions that can affect your eyesight and your overall well-being.

THE SCIENTIFIC STUFF!

Using our  3D OCT camera allows us to instantly diagnose a number of common conditions. The scan is non-invasive, painless, simple and quick.

WHAT CAN THE SCAN CHECK FOR?

Common conditions identified through regular OCT screening include:

1. Age-related Macular Degeneration

Macular degeneration causes the gradual breakdown of the macular (the central portion of the eye).

OCT not only identifies this condition and its type (there are two types, wet and dry) but also monitors its progress, for example if you are undergoing treatment for the condition, we can monitor how effective your treatment is. The risk of developing macular degeneration increases with age, and is the most common cause of vision loss in individuals over the age of fifty.

2. Diabetes

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

3. Glaucoma

Glaucoma damages the optic nerve at the point where it leaves the eye. Recent statistics suggest 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.

4. 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 we are looking directly at things, when reading, sewing or using a 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 eventually 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.

5. 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 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 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.
