What are we actually looking at during an OCT scan?
Almost 100% of our patients are now opting for a scan as part of their eye care, but do you know what it allows your optometrist to see?
OCT stands for Optical Coherence Tomography. It creates highly detailed images of the structures at the back of your eye, including the retina and optic nerve.
Think of it a little like being able to see beneath the surface rather than simply looking at it from above. These detailed images can help us detect and monitor subtle changes associated with eye conditions including glaucoma and macular degeneration, sometimes before you’ve noticed any change to your vision.
We can also compare scans over time, helping us identify changes that might otherwise be very difficult to spot.
It’s quick, non-invasive and gives us an extraordinary amount of information about the health of your eyes.
