[Reprint rl'quests to R. W. Beck. MD, Kellogg Eve Center, 1000 \Vall St., Ann Arbor, MI -181O:=;.J In general, visual acuity loss in association with optic nerve drusen arises lrom the developml'nt and bleeding of subretinal neovascular membranl's. Beck l'l .II. report the cases of four patients with optic nen'e drusl'n but no retinal pathology who had stepwise Visual IllS, 111voh'ing visual field and acuitv Other possible ,aust" lor visual loss were reasonably excludl'd. Thl' authors postulate a vascular basis for this stuttering visual loss. Reviews cited show that only a very low pl'rcentage of patients with optic nerve drusen lose vision in this fashion, and the authors rightly admonish that "reduced visual acuity should nl'v,'r be presumed to be due to drusen until compressiun [of the optic nerve] by a mass lesion is ruled uut."
