What is OCT?
In 2013 we invested in a new piece of technology that is not widely found in Optometric practice. It is called Ocular Coherence Tomographer. This is a 3D scan of the back of the eye. Retinal photography shows us a birds eye view of the back of the eye from above, the OCT uses cross-sections to shows us all the different layers of the retina- the light sensitive tissues of the eye. The machine uses light rays to look at all these layers.
It allows us to look for diseases of the eye such as Glaucoma, Macular Degeneration, Diabetic Retinopathy, Epi-retinal Membranes, Hypertension and many more. Using the OCT we are able to detect problems that we cannot otherwise see. It also allows us to more accurately diagnose and therefore treat any problems. It can also allow us to detect problems earlier, to make treatment and therefore the outcome much better. It is a piece of equipment that they also use at the hospital.
It is easy and simple to have the scan done. It is pain free and just involves looking at a green cross for a few seconds, then a brighter flash. We highly recommend this to patients over the age of 40, for anyone with a family history of eye problems and smokers.
Is there a 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. You can chose to pay at your visit, or join a scheme so the cost is routinely covered.
A Step-by-step approach:
Having an eye scan is simple and painless, just follow the steps below to bring about peace of mind.
We will scan your eyes using the state-of-the-art 3D OCT Camera from Topcon.
The high resolution 3D images are examined by the optometrist using specialist built-in analysis tools.
The results are presented to you.
Any future scans can be compared with previous ones for comparative diagnosis.
It used to be that the only way of examining the eye was with an ophthalmoscope. Although still useful it’s limited by only showing a small area at any one time.
Our digital camera allows us to take images of the back of the eye, enabling more of the retina to be seen at once and allowing us to see inside your eye. However, this equipment only has the ability to scan the surface of the back of the eye, and as it cannot see beyond this, it is unable to spot any problems which may be happening in one of the other layers of the eye.
Our new OCT scanner has the ability to scan many different layers of the retina. This latest technology now allows the optician to identify problems that they wouldn’t otherwise be able to see with just their standard eye testing equipment and cameras. Our opticians are recommending that all of our patients take advantage of the new equipment as part of a thorough eye examination. The diagrams here shows the layers of the eye within the retina, which when studied, are key to discovering serious eye conditions such as Macula degeneration, Glaucoma, and Diabetic Eye Disease even if it is behind a cataract. We then have the huge advantage of taking action before you are even aware you have a problem. For ultimate peace of mind, our opticians recommend you book an OCT scan as part of your next eye examination with us.
You only have one pair of eyes. Our OCT scanner can identify the following eye conditions before they begin to affect your vision. This gives us a huge advantage when it comes to helping to prevent symptoms from developing.
Macular degeneration causes a gradual breakdown of the macular.
The OCT scanner can not only identify this condition and its type (wet or dry) but also detect it earlier.
Glaucoma damages the optic nerve. The danger with chronic Glaucoma is that there is no pain and no loss in your central vision in the early stages, such that you would notice something was happening. Also looking at just a surface view of the optic nerve with the traditional optical equipment only gives us limited information about it too.
Our OCT scanner will show cross sections through the nerve which enables earlier detection.
Diabetic retinopathy is a major case of visual impairment among adults. In the UK, more than two million people have been identified as having diabetes.
Our OCT scanner enables early detection, which greatly improves success rate of treatment.
Cataract is more common as we get older and does not have to be in the family for someone to develop it. A normal eye test may give a limited view of the back of the eye. An OCT scan can still get a good image of the back of the eye where a normal camera may not.
Our OCT can see through it and allow an important examination of the retina and beyond.
Retinitis Pigmentosa is an inherited degenerative eye disease that caused degeneration of the retina. The diagnosis relies upon documentation of progressive changes in your vision.
Our OCT scanner is designed to monitor progressive changes which enable us to identify this condition.
