An illustration of dry age-related macular degeneration,a medical condition in which damage to the retina leads to progressive vision loss in one's central field of vision. The macula is a region near the centre of the retina with a high density of photoreceptors responsible for high acuity vision. In dry AMD,cellular debris called drusen accumulate between the retinal pigment epithelium and the choroid. As a result,photoreceptor cells in the retina can no longer receive nutrients or pass on waste to the blood vessels in the choroid and become damaged | |
