Traumatic bitemporal hemianopsia and diabetes insipidus.

Bitemporal hemianopsia and diabetes insipidus are infrequently occurring complications of closed head injuries. Porter and Miller found 18 cases of posttraumatic diabetes insipidus among more than 5000 patients with nonfatal closed head injuries. Of these, five also manifested damage to the optic chiasm. In 1971 Laursen surveyed the literature regarding traumatic bitemporal hemianopsia and found associated diabetes insipidus in 26 of 50 patients for whom information on this was given. Both conditions were present in a patient seen at Walter Reed Army Medical Center.
