Abstract
Although usually a manifestation of vestibular or neurological disease, acquired nystagmus occasionally can be seen in ocular diseases such as ocular albinism and cone dystrophy. The present case of cone-rod dystrophy presenting with acquired dissociated vertical nystagmus probably demonstrates another unusual manifestation of cone-rod dystrophy.
