In short, yes. While diabetic screenings and OCT scans both involve imagery of the back of your eye; there are actually some significant differences.
Where a diabetic check involves a fundus picture or digital retinal photography, which captures a superficial image of the retina located at the back of your eye, OCT scans take over 1,000 scans in a matter of seconds which allows us to look at the many layers beneath the surface of your retina. This helps us to detect any changes to your eye health up to five years earlier than simply looking at the surface.
In addition to detecting eye problems linked to diabetes, OCT scans also allow us to detect a wider range of eye problems earlier.
