The patient has suffered blunt trauma to the eye, most often resulting from a blow, a fall, a sports injury, or a car accident, and is alarmed because of the swelling and discoloration. Family or friends may be more concerned than the patient about the appearance of the eye. There may be an associated subconjunctival hemorrhage, but the remainder of the eye examination should be normal, and there should be no palpable bony deformities, diplopia, or subcutaneous emphysema (Fig. 23.1).
