Marcus Gunn jaw winking with trigemino-abducens synkinesis.
Congenital ocular aberrant innervation syndromes are a complex group of disorders involving abnormal miswiring of the extraocular muscles. This case report describes a child with both a right Marcus Gunn jaw winking phenomenon and a right trigemino-abducens synkinesis, which has not previously been reported in the literature. Clinically, this child presented with an intermittent elevation of the right eyelid and/or an intermittent right exotropia when opening her mouth while sucking or chewing. This case suggests the primary abnormality in this patient may be abnormal development of the trigeminal nerve resulting in the eyelid abnormalities and strabismus.
