Adaptive Optics Reveals More About the Retina
Adaptive optics is a new technique that allows closer examination of the retina than ever before. Researchers at the University of Rochester recently used adaptive optics to learn more about a rare form of colour blindness called dichromatic colour blindness. It is hoped the technique will help researchers to learn more about other retinal conditions.
The research, published in the Proceedings of the National Academy of Sciences and reported by BBC News, showed that although one colour blind subject was missing nearly a third of the normal number of cones, vision was otherwise normal.
Lead researcher Dr Joseph Carroll was quoted as saying,

Lead researcher Dr Joseph Carroll was quoted as saying,
If a third of the light-receiving cells in your eye are absent and you don't even notice it, it means that when a patient complains to a doctor about waning light sensitivity, then the damage must already be very serious.
