Do you know what this is a picture of?
An artist's impressionist piece displaying the relationship between the land and sea?
A satellite image of a newly discovered road on the moon?
It is a 3D image of the back of an eye in which an epiretinal membrane has developed.
Below is a 3D image of a healthy eye with no macular damage. At first glance it may look like there isn't much of a difference, but the impact this can have on the vision can be very bothersome.
These 3D scans were taken with an OCT (Optical Coherence Tomography) device, which is the most advanced equipment available for the early detection and subsequent correction of ocular health issues; most good eye hospital departments will have an instrument like this. Less than 10% of Optometrists have this equipment in their practice, with many opting only for 2D retinal photography instead; meaning they aren't able to see this much more useful cross section of the different layers of the retina.
This macular damage was discovered by Brad whilst conducting an eye examination in the practice. Had he not performed the OCT scan, and only taken a basic 2D retinal photograph, the damage would not have been spotted and subsequently corrected before any lasting damage could occur.
