AI is also able to determine your sex from your retinal scan with very good levels of certainty (provided that your retina is healthy; its ability to tell sexes apart drops in diseased retinas). [0]

Which came as a surprise to the ophthalmologists, because they aren't aware of any significant differences between male and female retinas.

I am surprised that this is a surprise. At least color vision is encoded in the X-Chromosome so there should be variation as males have only one which can be expressed.

It is a surprise, because the retina as an organ is very well visible and observable in living people, so we have a ton of observational data and practical clinical experience. But despite that, humans haven't noticed anything.

I've never seen a retina which had been separated from a human.
