Eye Contusions and Lacerations
Eyelids
Eyelidcontusions(which result in black eyes) are more cosmetically than clinically significant, although more serious injuries may sometimes accompany them and should not be overlooked. Uncomplicated contusions are treated with ice packs to inhibit swelling during the first 24 to 48 hours. Minor lidlacerationsnot involving the lid margin or tarsal plate may be repaired with nylon or polypropylene (or, in some populations such as children, absorbable suture such as plain gut) 6-0 or 7-0 sutures. Lacerations of the lid margin are best repaired by an ophthalmic surgeon to ensure accurate apposition and to avoid a notch in the contour. Complicated lid lacerations, which include those of the medial portion of the lower or upper eyelid (possibly involving the lacrimal canaliculus), through-and-through lacerations, those in which the patient has ptosis, and those that expose orbital fat or involve the tarsal plate, should also be repaired by an ophthalmic surgeon.
