Answer A. Reduced levator palpebrae function
Explanation: A patient with congenital ptosis will present with minimal to absent levator function, often with an absent lid crease. Frontalis function is normal. An aberrant connection between CNs III and V is seen in Marcus Gunn jaw winking phenomenon. Patients with aponeurotic ptosis present with an abnormally high lid crease secondary to levator dehiscence.
