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.
Drusen are associated with aging and macular degeneration are distinct from another clinical entity, optic disc drusen, which is present on the optic nerve head.Both age-related drusen and optic disc drusen can be observed by ophthalmoscopy.hether drusen promote AMD or are symptomatic of an underlying process that causes both drusen and AMD is not known, but they are indicators of increased risk of the complications of AMD. 'Hard drusen' may coalesce into 'soft drusen' which is a manifestation of macular degeneration.
