title: Congenital trochlear-oculomotor synkinesis.
abstract: Synkinesis of the extraocular muscles forms a subset of congenital ocular motility abnormalities termed congenital cranial dysinnervation disorders. Synkinesis most frequently involves the abducens or oculomotor nerves and rarely the trochlear nerve. Only 3 such patients have been described in the literature. We report an isolated case of trochlear-oculomotor synkinesis in a healthy 6-year-old boy and discuss the proposed pathophysiology of this disorder.
