OCT 3D Scan
Discover eye conditions several years early with an OCT 3D scan, which provides a detailed understanding of how healthy your eyes are. The 3D scan costs just £10 on top of the cost of a standard eye test and is available in 315 stores, which you can see further down the page. Read on to find out more about the benefits of OCT 3D scan.
How does the OCT scan work?
The OCT 3D scan works like an ultrasound. However, rather than using sound waves, it uses light waves to see the detailed layers of the retina. The retina is at the back of the eye. It converts light into images, which allows you to see.
The OCT machine takes over 1,000 images of your eye, from the retina to the optic nerve. This then creates a detailed 3D image, which lets us see your eye's structure.
Benefits of an OCT eye test
There are many benefits to having an OCT 3D scan. Just like regular retinal photography, it is non-invasive, completely painless procedure. It only takes just a few seconds and costs just £10 on top of your standard eye test.
The main benefit to having an OCT 3D scan is that it can diagnose eye conditions and diseases earlier than other eye examinations, including those with no symptoms.
The 3D images let us see even subtle changes in your eyes, including the vitreous, retina, macula and the optic nerve. Many of the issues the OCT 3D scan detect form at the back of the eye.
You can find out more about conditions the 3D scan can identify below:
Glaucoma is the name given to a group of eye conditions which affect the optic nerve, as it joins the back of the eye. The optic nerve passes information like brightness, colour and contrast, from your eye to your brain.
Most types of glaucoma have no symptoms, so a regular eye test is the only way to know you have the condition. The OCT scan can detect glaucoma 4 years earlier than other eye tests.
Macular degeneration is a painless eye condition that causes you to lose central vision, usually in both eyes. It's one of the leading causes of severe vision loss in over 50’s. There are 2 types of this condition, Dry AMD and Wet AMD. An OCT scan can diagnose aged macular degeneration so it can be treated early.
People with diabetes can experience a range of eye conditions, including diabetic retinopathy which damages the retina. In severe cases it can also cause loss of sight.
There are many different types of diabetic retinopathy. The OCT scan lets us see the slightest change in your retina, helping us to diagnose diabetic retinopathy early.
Some cases of this condition cannot be diagnosed with a normal eye test. Diabetic eye screenings are designed for people with diabetes, giving us a wider view of the retina.
A detached retina happens when the thin layer at the back of your eye becomes loose. Symptoms of this include:
- Blurred vision
- Flashes of light
- A sudden increase of floaters in your eye
- A dark curtain moving across your field of vision.
If this isn’t treated quickly, it can permanently affect your sight. If you suspect you have a detached retina, you should see your optometrist or doctor right away.
The macular is a part of the retina. A macular hole can open in the retina, causing blurred and distorted vision. The condition isn’t painful; however, you can see a black or missing patch in the centre of your field of vision.
Optic nerve inflammation, also known as optic neuritis, can happen when your optic nerve becomes inflamed. The effects of this condition are quite sudden. Some of these include blurry vision, inability to see colour and pain when moving your eyes. This condition is common in people with MS (multiple sclerosis).
Retinal vein occlusion can happen when a blood clot blocks the retinal vein. This condition is more common in people with diabetes. An OCT 3D scan can detect retinal vein occlusion by examining the back of your eye.
You can see our eye health page for more information on eye conditions and symptoms. If you are concerned about your eye health, you can talk to us in store, where we can give you a normal eye test or an OCT scan.
