Abstract :

The Marcus Gunn syndrome or what also called Synkinetic Jaw Winking Phenomenon is a very rare genetic disorder that usually present at birth. Common physiologic examples of synkineses occur during sucking, chewing, or conjugate eye movements. There are also several abnormal cranial nerve synkineses, both acquired and congenital. Marcus Gunn jaw winking is an example of a pathologic congenital synkinesis. First described by the ophthalmologist Marcus Gunn in 1883, this condition presents in approximately 5% of neonates with congenital ptosis. It is characterized by unilateral upper eye lid ptosis with movement of the affected eye lid during jaw movement. Other eye abnormalites and vision abnormalites may also occur like amblyopia (in 54% of cases), anisometropia (26%) and strabismus (56%). We report a 10 year old boy presenting a unilateral Marcus Gunn syndrome that was discovered during routine clinical examination and will discuss the pathogenesis and clinical appearance of this syndrome.
