Drusen, from the German word for node or geode (singular, "Druse"), are tiny yellow or white accumulations of extracellular material that build up between Bruch's membrane and the retinal pigment epithelium of the eye. The presence of a few small ("hard") drusen is normal with advancing age, and most people over 40 have some hard drusen. [1]
Soraprazan (remofuscin) has been found to remove lipofuscin from retinal pigment epithelial cells in animals. [24] This opens up a new therapy option for the treatment of dry age-related macular degeneration and Stargardt disease , for which there is currently no treatment.
Choroidal nevus with drusen can be considered as a sign of chronicity since drusen take years to develop and appear. [14] Drusen are composed of lipids and can actually be an indicator that a tumour is a benign nevus as opposed to a cancerous melanoma. [15] In nevi imaged by OCT, about 41% are found to have drusen.

In the event of an injury that damages the skin's protective barrier, the body triggers a response called wound healing. After hemostasis, inflammation white blood cells, including phagocytic macrophages arrive at the injury site. Once the invading microorganisms have been brought under control, the skin proceeds to heal itself.
In children, optic disc drusen are usually buried and undetectable by fundoscopy except for a mild or moderate elevation of the optic disc. With age, the overlying axons become atrophied and the drusen become exposed and more visible. They may become apparent with an ophthalmoscope and some visual field loss at the end of adolescence.
