The white part is not strictly the optic nerve, but is in fact your optic disc - it is the "blind spot" of your eye as there are no receptors located in that circle. The other spot is your macula lutea, of which the fovea is only a part -it is the thinnest section of the whole retina, and appears as a small area with a hint of yellow colouration. The macula has a larger proportion of cones over rods in its cell makeup, which grants a greater visual sensitivity to colour and bright light. This allows the eye to see in colour rather than black and white, as well as permitting sharp focus. Minus a few points to Vision Express as well. Not a very well exposed fundus picture really.

With retinal scans in your ID cards soon, I'll be able forge one and say I'm you. James, it’s Big Dave from DA ;)
