Delayed onset of upper lid edema with exuberant chemosis developed in
a 3-year-old girl following blunt periorbital trauma. Examination unde
r anesthesia demonstrated a tightly everted upper tarsus that focally
compressed the underlying conjunctiva at the superior tarsal border. I
njection of subconjunctival hyaluronidase followed by local compressio
n and temporary tarsorrhaphy resulted in rapid resolution of the chemo
sis and restoration of the normal lid position.
