“ My eye test at Buchanan Optometrists saved my life ”

Heidelberg Spectralis 4D OCT Eye Scan

An OCT (optical coherence tomography) retina scan is entirely different from the routine eye photos taken by a lot of opticians or your diabetic clinics. The OCT instrument scans below the eye’s surface using safe low powered lasers. It is completely painless, non-invasive and takes only a matter of seconds. Your results are available instantaneously, and it is a great way for you and your optometrist to gain a better understanding of the health of your eyes or any eye conditions.

Buchanan Optometrists are one of the first practices in the UK to offer you the new Spectralis 4D OCT (Optical Coherence Tomographer) Retinal Scan. Using this phenomenal machine and incredible computer technology we can now diagnose so many more eye problems at the earliest possible stage. We can treat eye conditions sooner and prevent many from even developing at all which is the main aim of our job, maintaining your sight.

The Retina is the inner lining at the back of your eye. It acts in a similar way to the film in a camera, capturing the image of what you see and then transferring this image to the brain for interpretation. When an Optometrist looks into your eye or takes a photograph, it is the retina that they are looking at.

Conventional digital cameras, used in many opticians, just look at the top surface of the retina, but a lot of problems in the eye start at a deeper level. The Spectralis 4D OCT Eye Scanner is the equivalent of a CAT scan of your eye. Unlike retinal photographs, this new system not only allows us to take a very high-resolution detailed image of your retina but also helps us look below the surface at each layer of the retina to create a High-Definition map that provides us with information never before available. We can even see details in the walls of your blood vessels and tiny individual nerve fibres. This helps us to find the smallest sign of problems such as diabetic eye disease, vascular problems, neavi (moles), glaucoma, macular degeneration, oedema and retinal holes long before they may be visible on the retinal surface and can be seen by standard retinal photography or by looking into your eyes (ophthalmoscopy). The new Spectralis 4D OCT can help us diagnose and monitor all these conditions with the accuracy of one thousandth of a millimetre. Earlier detection leads to earlier treatment, a better prognosis and in some cases prevention of conditions developing at all.

The Spectralis 4D OCT scan not only helps us detect eye conditions but can sometimes also show signs associated with brain tumours, high cholesterol or uncontrolled blood pressure thus saving further health problems in the future and may even help prevent a stroke or heart attack.

We recommend Spectralis 4D OCT scanning for all patients as it not only acts as a very thorough assessment of your eye health but also an excellent base line for future comparison to help diagnose any changes at the earliest signs. Scanning is particularly advisable for anyone that has been diagnosed with cataracts, macular degeneration, glaucoma, diabetes or who has a family history of any of these conditions.

Heidelberg Spectralis 4D Optical Coherence Tomographer eye scanner uses a very safe low-powered imaging laser, to accurately measure the thickness of the nerve fibre layer.  It is a safe, non-invasive technique and doesn’t use any harmful rays like x-rays.

The process requires you to place your chin on a rest, much like many of our other instruments and look at a fixation light.  Unlike the standard cameras most opticians use, we get a very sharp clear image without dilating your pupils and even through cataracts. Each scan takes just a few seconds on each eye. It does not touch your eye and requires no drops so you can drive straight after your appointment.

After the images have been viewed and assessed, they are stored electronically for your next visit, where referring to the previous images we can spot even tiny changes (1 micrometer!). This allows for an easier and more accurate method of monitoring the health of the eyes year after year. If necessary, the retinal images can be passed on to GPs or Hospitals for their reference too. Spectralis 4D OCT eye scanning is recommended for all adult patients and can be used at any age if recommended by your Optometrist.

The 4D Spectralis OCT also has a unique role in macular disease and glaucoma detection.
