This is an ill-defined syndrome with the primary features of facial weakness and limited ocular abduction, usually bilateral and nonprogresssive. Those who first described this entity in the 19th century, von Graefe and M√∂ebius, accepted only cases with facial diplegia and bilateral 6th nerve palsy. Since then, however, a large number of associated nerve palsies and systemic malformations have been reported. More than a third of patients have features of Duane’s syndrome. Beyond the oculomotor dysfunction, no ocular abnormalities are consistently associated.
