How can optic nerve drusen affect vision?
Optic nerve drusen usually do not affect vision. However, peripheral vision loss may occur so slowly and be so minimal that the abnormality is never noticed. Less commonly there may be an abrupt, painless loss of part of the peripheral vision. A rare complication from optic nerve drusen is choroidal neovascular membrane, an abnormal blood vessel that grows beneath the retina near the optic nerve.
