Optic nerve drusen commonly cause mild side vision loss that can be detected by machines in the doctors office called visual field analyzers. The side vision loss is usually not appreciated by patients and not a functional concern. Rarely the drusen can cause severe, noticable side vision loss. It would be extremely rare for drusen to cause central vision loss, usually as a result of a choroidal neovascular membrane, which is a growth of new blood vessels near the optic nerve. These blood vessels can leak or bleed, causing loss of vision.
