Having a 4D OCT scan is an important part of your eye examination. This advanced scan is quick, easy and completely non-invasive, and performs a comprehensive assessment of your eyes while allowing your optometrist to maintain a COVID-safe distance.
What is an OCT scan?
Your retina can reveal a lot about your eye health. Changes to the retina can indicate the onset of sight-threatening diseases including age-related macular degeneration, glaucoma and diabetic retinopathy. While traditional retinal imaging provides a limited picture of the back of your eye, the 4D OCT scan gives a much more detailed image, including the different layers and thickness of the retina and the structure of the eye.
Our Spectralis® OCT machine
We use the latest retinal imaging technology. Our advanced Heidelberg scanner features Widefield imaging, MultiColor, and BluePeak. These cutting-edge features provide a high-resolution, high-contrast and intricately detailed image of the back of your eye, making it possible to detect even the slightest abnormalities. The Spectralis® also has an advanced Glaucoma Module, which tests your scan against a reference database of normal eyes. This means that we’re able to detect any tiny deviation which could indicate the onset of glaucoma.
The results of your scan are instant. Your optometrist will talk you through your results so that you have a good understanding of what’s happening with your eyes.
Regular scans track changes
Your scan results are saved on your file. Each time you come for a scan, your optometrist will compare the results with your previous scans, checking for even the smallest changes that could indicate deterioration, disease progression, or the early onset of a problem. By having regular eye examinations you can ensure your eye health for the years to come.
A COVID-safe eye exam
The 4D OCT scan is an essential part of our eye exams for adults and children, and is one of the ways we’ve adapted our assessments to be COVID-safe. Without an OCT scanner, your optometrist would have to get very close to you to examine your eyes, which is difficult while using the required PPE. By investing in the Spectralis® we’re helping our patients and staff to stay safe while enabling us to carry out much more detailed examinations.
