Optical Coherence Tomography (OCT) is a cutting-edge eye scan suitable for all ages. Similar to an ultrasound, OCT uses light instead of sound waves to capture highly detailed images of the layers at the back of your eye. Our advanced 3D OCT system not only provides a cross-sectional view of your retina but also takes a digital photograph of the eye’s surface, allowing us to compare and pinpoint any areas of concern with exceptional accuracy.
The biggest advantage of OCT technology is its ability to look beneath the surface of a standard retinal image, offering a three-dimensional view of your eye’s internal structures. This makes it easier than ever to detect, monitor, and locate potential eye conditions at their earliest stages. Your optometrist can digitally analyse these images, layer by layer, to identify any issues that may require further investigation.
With this state-of-the-art diagnostic tool, we can confidently detect and manage eye conditions and refer you for specialist treatment if needed. At Nethercott Optician, we are committed to providing the highest level of eye care, and OCT scanning is now available as part of your eye test. While there may be an additional charge, the benefits are clear—OCT technology can track even the most subtle retinal changes over time, giving you a valuable, ongoing record of your eye health.
Using the state-of-the-art Topcon 3D OCT camera, we capture both a high-resolution digital photograph and a detailed cross-sectional scan of the back of your eye. This advanced technology allows us to detect and diagnose a range of common eye conditions instantly.
One of the key benefits of OCT scanning is its ability to track even the smallest changes in your retina over time. With each eye test, the software compares previous scans, creating a valuable ongoing record of your eye health. This ensures that any potential issues are identified as early as possible, helping to protect your vision for the future.
An OCT scan helps identify and monitor various eye conditions at an early stage, allowing for timely treatment. Some of the most common conditions it can detect include:
1. Age-Related Macular Degeneration (AMD)
AMD is a condition that affects the macula, the central part of the eye responsible for sharp vision. Over time, it can lead to vision loss. There are two types of AMD—wet and dry—and an OCT scan can not only detect the condition but also track its progression, especially if you're receiving treatment. The risk of AMD increases with age, making regular eye exams essential for those over 50.
2. Diabetes & Diabetic Retinopathy
People with diabetes are at risk of diabetic retinopathy, a condition that damages the blood vessels in the retina and can lead to vision loss if left untreated. More than two million people in the UK have diabetes, and an OCT scan helps detect early signs of this condition, improving the chances of successful treatment.
3. Glaucoma
Glaucoma is a disease that damages the optic nerve, often without any noticeable symptoms until significant vision loss occurs. It’s more common in people over 40, affecting around 2 in 100 people. An OCT scan can detect early signs of glaucoma, allowing for prompt treatment before it causes permanent damage.
4. Macular Holes
A macular hole is a small tear in the macula, the part of the retina responsible for clear central vision. This can make tasks like reading, sewing, or using a computer difficult. Macular holes can form due to aging, vitreous detachment (when the eye's gel-like substance pulls on the retina), or extreme sun exposure (such as staring directly at an eclipse). OCT scans help diagnose and monitor this condition.
5. Vitreous Detachment
As we age, the vitreous gel inside the eye becomes more fluid and can pull away from the retina. In some cases, parts of the vitreous remain attached, causing tension on the retina, which may lead to distorted vision or retinal damage. Vitreous detachment usually has no pain or immediate symptoms, but an OCT scan can identify any hidden issues and assess whether treatment is needed.
Regular OCT scans provide a detailed and ongoing record of your eye health, helping to detect these conditions early and protect your vision for the future.
No, the OCT scan is painless. It’s a non-invasive procedure, and there’s no need for eye drops or any form of discomfort. The OCT scan is quick and typically takes only a few minutes to complete. There are no risks associated with the OCT scan. It’s a completely safe procedure that involves no radiation, and it’s suitable for people of all ages.
