What is OCT?
The OCT (Optical Coherence Tomography) machine is a wonderful piece of technology. It allows us to produce an exact 3D model of the inside of your eye. The scan takes seconds and is entirely painless. It does not damage your eyes in anyway and the results are processed and displayed within minutes. These results allow us to monitor any changes over time. Because conditions like glaucoma progress very slowly and can be difficult to detect in the early stages. The OCT helps us to monitor any progression.
Your Optometrist will discuss the results with you. Show you the images and measurements and will answer any questions you may have.
The OCT provides incredibly precise measurements allowing us to monitor the health of your eye extremely closely. Checking for tiny changes from one visit to the next. This provides reassurance to you and your Optometrist that you are receiving the very best care. If an eye condition were to develop, the OCT scan would allow treatment to start at the earliest point possible.
Common questions asked about OCT scans
How long does it take?
The scan itself takes around 6 minutes with a further ten minutes to discuss the results
Who should have an OCT scan?
While an OCT scan is more important in some scenarios, for example anyone with a family history of Glaucoma, the scan can show minute changes in your eyes which could go undetected during a regular eye exam.
What’s the difference between a retinal photograph and an OCT scan?
Retinal photography is a two dimensional photograph of the back of the eye. Whilst useful, this older technology does not look beneath the surface of the retina (the back of the eye) and is less effective at early diagnosis.
