User testing
Since I occasionally ask users to be involved in trials and testing, when someone asks me I feel I have to agree, so I've spend part of this morning having my retina photographed.
Eye drops dilate the pupil, and then the eye is photographed in rapid succession a number of times, in order to capture the sorts of images shown above. This is used as source data for a mathematical and computational model of the properties of the retina based on its light transmission and reflectance properties, which can be used in non-intrusive diagnosis.
The procedure is painless, and whilst it causes local blurring of vision in one eye, it hasn't stopped my doing my normal work and is now (a couple of hours afterwards) almost back to normal. If anyone else feels like supporting the work, send me your email and I'll pass it on.
