Atrophy of Photoreceptors
Everyone has specialized cells in the retina that respond to light and protect the eye.
These cells are called photoreceptors, and one of their functions is to prevent excessive light from entering the eye and causing damage to the retina. The growth of drusens cause these photoreceptors to breakdown or die, leading to vision loss.
Atrophy of Retinal Pigment Epithelial (RPE) cells
This is a medical term for the layer of cells located directly behind the photoreceptors. The purpose of these cells is to nourish the eye, particularly the retina.
Your eye doctor will be able to identify AMD by noticing the growth or formation of abnormal blood vessels under the macula. These vessels can break or leak, resulting in bleeding, scar tissue and loss of vision. This sign can be seen only in Wet Age Related Macular Degeneration.
