The drusen will not be affected by your fall. A few drusen - all by themselves - usually will not affect your vision. You must have some more extensive problem like macular degeneration or rpe detachment or severe optic disc drusen. something else. Simply having drusen is very common - so your description of what you have is not specific enough for me to help. Do you have optic disc drusen or macular drusen?? What is you treatment regimen? These are very basic questions. Need more info?
