Periorbital necrotising fasciitis.

Three cases of periorbital necrotising fasciitis are described, one occurring in a three-year-old child. The cases in adults required debridement of necrotic tissue, in one of whom there was extensive disease involving the face and orbital fat. It is probable that the early stages of this condition are under-recognised; the importance of early signs and intensive treatment of this life-threatening disease are illustrated.
