Fifty-one patients had nuclear or infranuclear findings,ie,trochlear palsies(n=20),oculomotor palsies(n=17),abducens palsies(n=7),combined palsies(n=5),and restrictive ophthalmopathy(n=2).Nine patients had supranuclear dysfunction,including seven patients with convergence insufficiency.Bilateral ocular motor palsies and combined palsies were significantly(by means of X2 test)associated with head trauma of severity sufficient to cause corticospinal tract dysfunction.Individual or combined ocular motor palsies were not significantly(by means of X2 test)associated with intracranial hemorrhage and/or skull fracture or loss of consciousness.Trochlear palsy was the most common nuclear or infranuclear basis for traumatic diplopia,and convergence insufficiency was the most common supranuclear cause of double vision.Head trauma distinguishes by upper motor-neuron signs was correlated with specific subsets of disordered ocular motility. |
