Live Images of the Retina Show Big Differences
Live images of human retinas reveal that even normal retinas differ in the amount of red, green and blue cones, and that the brain plays a bigger role in vision than we think. The technology used to take the images could also be used to investigate forms of retinal disease. The research was published in The Journal of Neuroscience.

"[This] suggests that there is a compensatory mechanism in our brain that negates individual differences in the relative numbers of red and green cones that we observed," Joseph Carroll, a researcher at the Center for Visual Science at University of Rochester and a collaborator of the study, told LiveScience.
The researchers took advantage of adaptive optics imaging, which uses a camera containing a corrective device that cancels the effects of the eye's imperfect optics on image quality, to produce a high-resolution retinal picture.
