Unfortunately the term "drusen" is used for a variety of conditions that are unrelated: thus there is optic nerve drusen, soft macular drusen, hard macular drusen, and midperipheral drusen. What type do you have? The worse problem is soft macular drusen which may lead to macular degeneration. Hard macular drusen and midperipheral drusen rarely cause any problem. Optic nerve drusen usually doesn't create a problem and there is no treatment for it.
