Ocular involvement in benign botulism B.

In nine cases of botulism B infection due to food poisoning acute onset of accommodation paresis, mydriasis, and dry-eye symptoms were the prominent clinical findings. Impairment of salivary secretion as a further effect upon cholinergic autonomic innervation was detectable for months. Guanidine treatment had a beneficial effect, whereas administration of antitoxin in the late and benign form was not effective.
