Monocular blindness developing 7 days after repair of zygomaticomaxillary complex fracture. A clinical report.

Blindness following zygomaticomaxillary complex (ZMC) fracture and surgical repair is an unfortunate and uncommon complication. A review of the literature reveals fewer than 25 cases of monocular blindness resulting from zygomaticomaxillary fracture or repair. The case presented here is that of a man who was assaulted with a baseball bat and suffered a mildly displaced ZMC fracture. On admission, the patient had light perception only in his left eye. During his convalescence, vision in his left eye gradually improved to the point of allowing him to read a newspaper without difficulty. Then, 9 days after the injury (7 days after surgical repair), the patient awoke with complete blindness of the left eye. The possible mechanisms for such loss of vision are discussed.
