[Drusen papilla with vision disorder and pathologic visual evoked potentials]

Six cases of optic nerve head drusen ophthalmoscopically are reported. Five of these had pathological latencies of the P 100 potentials on VEP examination. Only three of the patients had subjective visual complaints; all six, however, had variable visual field defects. Optic nerve head drusen are an important differential diagnosis, which can be readily established especially in those younger patients who need neurological and ophthalmological examination because of visual disturbances and pathological VEP responses.
