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.
This type of drusen may not cause vision problems for a long time, if at all. âSoftâ drusen are large and cluster closer together. Their edges are not as clearly defined as hard drusen. This soft type of drusen increases the risk for AMD. Drusen of the optic nerve Drusen can also occur in the optic nerve. These drusen are made up of protein and calcium salts and generally appear in both eyes. Unlike the drusen associated with AMD, optic nerve drusen (also known as optic disc drusen) are not related to aging and often appear in children.
