Answer

Late ocular manifestations include the following:

  • Mild, generalized mass contracture of the facial muscles, rendering the affected palpebral fissure narrower than the opposite one (after several months)

  • Aberrant regeneration of the facial nerve with motor synkinesis

  • Reversed jaw winking (ie, contracture of the facial muscles with twitching of the corner of the mouth or dimpling of the chin occurring simultaneously with each blink)

  • Autonomic synkinesis (ie, crocodile tears—tearing with chewing)

  • Permanent, disfiguring facial paralysis (rare)
