Canine Tooth Syndrome Following Occipital Impact Closed Head Injury

Abstract

Canine tooth syndrome is an ocular motility disorder comprising ipsilateral Brown's syndrome and superior oblique muscle dysfunction. Ocular motility shows ipsilateral deficit of elevation and depression, maximum in an adducted position. Typically this follows a dog bite (hence the name) that damages the trochlea and superior oblique muscle concurrently. We discuss a patient with canine tooth syndrome presenting subsequent to a closed head injury with impact to the occipital bone, which, to our knowledge, is a novel occurrence of this syndrome.
