Document Summary

The postage stamp thin layer filled with rods and cones (photoreceptors) Ganglion cells stake the signal out the back of the eye. Rod are good for low light intensities but they can not give you any fine detail. Cones are good for daylight conditions and are good for color. In the corners of our eyes we have no cones that"s why there is no colour vision. Detached retina: the retina lifts off from the back of they eye creating a hole from the retina. Floaters: chunks of tissue floating around the vitreous humor. So they damage the retina with 100s of tiny burns, essentially like pruning a garden: diabetics are at a higher risk for cataracts. Tuesday, february 2, 2016: dry macular degeneration the drusen develop in the macula that cause the cones to die in that area because they are being pushed away from their source of nourishment. To treat this: wet macular degeneration this happens fast.
