Congenital total eversion of the upper eyelids.

Eight cases of bilateral and 6 cases of unilateral congenital total eversion of the upper eyelids are reported here. It is suggested that an appreciable overlapping of the lower eyelid margin by the upper eyelid is a predisposing factor in the mechanism of eversion in this condition. Treatment by injection of hyaluronidase into the chemotic conjunctiva followed by placement of a lid suture to revert the eyelid resolves the condition in 1 or 2 days.
