title: Rhinogenous optic neuritis with drastic diurnal variation of visual function.
abstract: We report a case of rhinogenous optic neuritis in a 50-year-old man demonstrating drastic diurnal variation in visual function. His left vision was 20/15 in the morning, which gradually decreased to counting fingers at night. Pupillary reaction and visual field showed the same fluctuation as vision. Complete remission of visual symptoms was achieved after endonasal ethmoid sinusotomy.
