The latest technology we have to offer you



Ultra-Wide View Daytona Fundus Camera


New camera that captures a 200 degree view of the retina, ensuring that the eye health examination is more detailed than ever.

This is particularly useful in detecting conditions/diseases affecting the peripheral retina, such as Diabetes, Blood Pressure and retinal tears/detachment. It is recommended for ALL patients. For more information, click here, or ask your Optometrist during your eye-examination.

It's now over 60 years since the Barnet Pepper ophthalmic practice in Pool street, Caernarfon first opened its doors. But, this practice certainly doesn't live in the past. We are at the forefront of the technological revolution. We were among the first in Britain to install and use the OCT (Ocular Coherence Tomography) This exciting new system gives instant images of the inside of the eye. The retina can be scanned for damage, damaged blood vessels and diseased nerve cells on a microscopic scale. At Barnet Pepper at least one image per eye is kept for future reference, making any subtle changes in the health of the eye easier to diagnose. When patients are referred to their GP, a photograph can accompany the report. this means that a specialist would be able to assess the urgency of the case without having to call the patient into hospital. If needed, we could send the image to a specialist anywhere in the world.

Digital Fundus Imaging System is also good news for diabetics since it provides the technology for early detection of diabetic retinopathy which ultimately causes blindness. Early detection could save their sight. Since long term diabetes can cause eye problems, if you are a diabetic it is very important to have regular eye examinations.

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

What is OCT?
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.

What does OCT cost?
There may be 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.

OCT screening will safeguard your eye health

The health of your eyes matters to you and it matters to us too, which is why we are offering OCT to all our patients.

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

a step-by-step approach

Having an eye scan is simple and painless, just follow the steps below to bring about peace of mind.

  • Step 1
    Book an appointment with your optometrist
  • Step 2
    The optometrist will scan your eyes using the state-of-the-art 3D OCT camera from Topcon
  • Step 3
    The high resolution 3D images are examined by the optometrist using specialist built-in analysis tools
  • Step 4
    The results are presented to you
  • Step 5
    Any future scans can be compared with previous ones for comparative diagnosis

The scientific stuff!
Using a Topcon state-of-the-art 3D OCT camera, your optometrist 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 instantly diagnose a number of common conditions. The scan is non-invasive, painless, simple and quick. What's more, the software can 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. Age-Related Macular Degeneration
    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.
  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 enables 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 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 being damaged.
