Congenital eyelid imbrication syndrome

Purpose To describe congenital eyelid imbrication syndrome and its possible pathophysiology. Design Clinical observational case report. Methods A full-term newborn was examined after a vaginal delivery and uneventful pregnancy. Results The upper eyelids were overlapping the lower eyelids when the eyes were closed or when the newborn was asleep. The upper eyelids resumed normal position gradually over a week without causing any symptoms or residual sequelae. Conclusions Eyelid imbrication syndrome is a rare cause of congenital eyelid malposition. It may be caused by inborn laxity of the upper medial and lateral canthal tendons that are tightened during the postnatal period, causing resolution of this condition.
