Hard drusen do not need to be treated. If your ophthalmologist finds hard drusen during a routine eye exam, he or she may want to watch them regularly to make sure they do not develop into soft drusen.
Because soft drusen are a sign of age-related macular degeneration (AMD), your ophthalmologist will follow the AMD treatment appropriate for you. Trying to eliminate the drusen will not improve your AMD.
If you have optic nerve drusen without symptoms, you should be monitored regularly. There is no treatment for optic nerve drusen. In rare cases where choroidal neovascular membranes develop, treatment may be appropriate.
