Reduced visual acuity apparently due to the effects of drusen on the optic nerve is rare. We describe two young patients with central vision impairment from optic disk drusen: a man with a reduction of visual acuity to light perception, a women with a very fast evolution of the drusen, that, not visible at the clinical onset, could be documented in autofluorescence one month later. The appearance of drusen in disks initially diagnosed as pseudopapilledema is supposed to be related to axonal degeneration from abnormal axoplasmic flow.
