title: Congenital upper eyelid retraction.
abstract: This report describes a six-year-old boy born with a unilateral upper eyelid retraction resulting in mild exposure keratopathy. The fissure on that side was 4 millimeters larger and lagophthalmos was present. At the time of levator recession surgery, the muscle was found to have a restriction at the medial and lateral horns preventing downward excursion. This condition has some of the features of congenital orbital fibrosis and is postulated to have been due to an intrauterine infection or inflammation.
