Congenital Eyelid Imbrication and Floppy Eyelid Syndromes Complicated by Eversion due to Prostaglandin E Infusion in a Patient With Trisomy 21 and Tetralogy of Fallot.

Congenital eyelid imbrication syndrome is a rare eyelid finding where a long upper lid overlaps the lower lid when the eyes are closed. To date, congenital eyelid imbrication syndrome has been described in the literature less than 10 times. We present a case of congenital eyelid imbrication syndrome in a patient with trisomy 21 and tetralogy of Fallot on a prostaglandin E infusion to maintain a patent ductus arteriosus prior to definitive heart surgery. While on the infusion, the patient developed peripheral edema and flushing due to vasodilation. This coincided with eyelid swelling, conjunctival chemosis, and eversion of the eyelids. Upon cessation of the prostaglandin E1 infusion, his eyelid eversion resolved.
