This heating and damaging of the retinal pigment epithelium causes the body to come in and do some repair work and, at the same time, some of these drusen can disappear and decrease in size, number and thickness.

... Rods and cones are supported by retinal-pigmented epithelium (RPE), a layer of cells near the retina. The accumulation of toxic pigments, or lipofuscin// results in the deterioration of the RPE leading to loss of rods and cones and subsequent central vision loss.
