From the website:
The inside of your eye is one thing you’re guaranteed never to get a good look at. Even if you could, the pupil is far too small an aperture to allow you to see the entire interior. University of Michigan ophthalmologic photographer Richard Hackel compares the problem to taking a picture of a room through a keyhole. To overcome this hurdle, Hackel uses a computer program to stitch together images taken from 20 different angles by a special digital camera. The result is an unusual, fully detailed map of the inside of a healthy 26-year-old’s eye.

It is amazing technology but doesn't need a computer program to piece together multiple photos to get the displayed photo.
A $40K digital fundus camera is all you need.
I'm an optical assistant and take upwards of 40 of these a day.
The reason for the clarity in the shot of the 26 year old example is due to the large pupil size of a younger person.
The above photos are posible with an older person but usually only after the above mentioned drops which dilate the pupils allowing the optometrist/opthalmologist to view the retina in extreme detail.
If anyone requests i will post some retinal photos of some truly amazing eyes
My violin teacher only became aware that he had diabetes when he could no longer read music or drive due to retinal deterioration. It is a pretty good tool.
It has a red and green laser that scans the retina in .25 secs and gives us 200 degree view of the retina.Awesome device plus we have caught numerous patients that wouldve lost their eyesight if it were not for the Optomap.Pt's also love the fact that we can email these images to them .Sreensaver anyone?
