By the way, doctor: What are drusen, and why do I have them?
Q. My ophthalmologist says I have drusen scattered over the macula in both eyes and wants to check them every nine months. Could you say something about what drusen are and what they mean?
A. Drusen are small, yellowish deposits of cellular debris that accumulate under the retina — the light-sensitive layer of cells at the back of the eye that's essential to vision. Drusen occur in most people over age 60 and are more common in women than men.
