These images are from "Reflective afocal broadband adaptive optics scanning ophthalmoscope" by Alfredo Dubra and Yusufu Sulai, that has just appeared in
Biomedical Optics Express, Vol. 2, Issue 6, pp. 1757-1768 (2011) doi:10.1364/BOE.2.001757 [here].
Image on the left shows the cones in the fovea. And that on the right shows a more peripheral retinal location: the large bright dots with a dark ring around them are cones, and the surrounding smaller spots are rods.
Question: A historical first - as advertised?

Answer: Fundus photography has come a long way. This one, ultra-micro-imaging of the human retina, is absolutely astounding, indeed a historic first. It'll be interesting to see images of diseased retina. No doubt this is being actively pursued. Our congratulations to Drs Dubra and Sulai.
