The health of your eyes is our number one priority. At McBride and McCreesh Opticians, we are proud to offer you the latest technology to examine your eyes. An Ocular Coherence Tomography (OCT) scan provides a 3D view of all the major structures in the eye allowing us to detect any possible eye abnormalities. We are the first practice in Fermanagh to offer this pioneering, highly advanced and non-invasive technology.
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 your eye. We also capture a digital photograph of the surface of your eye to cross-reference areas of concern.
OCT scans are normally provided in eye hospitals, but this state-of-the-art 3D technology is now available EXCLUSIVELY at McBride and McCreesh Opticians. You can enjoy the peace of mind that comes from knowing that your eyes are in great condition. OCT screening will safeguard your eye health against potentially serious ocular diseases. The charge for this service is £35 and is not covered by the NHS, but the health benefits are obvious.
Using a state-of-the-art 3D OCT camera, your optician will take both a digital photograph and a three dimensional cross sectional scan of the back of your eye in one sitting. This allows us to immediately diagnose a number of common conditions. The scan is non-invasive, painless, simple and quick – only taking a few moments to complete. What’s more, the software can automatically detect even the most subtle changes to the retina with every eye test you take. This provides you with an invaluable on-going record of the health and condition of your eyes.
Common conditions identified through regular OCT screening include:
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 undergoing treatment for such a condition. Unfortunately, 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.
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 enables early detection, which greatly improves the success rate of treatment.
Glaucoma damages the optic nerve at the point where it leaves the eye. Recent statistics suggest that some form of glaucoma affects around 2 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.
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.
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 can become 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 suffering damage.
We recommend that our patients consider utilising this advanced technology as a baseline scan is always useful for future reference and comparison.
