Spontaneous visual recovery from traumatic optic neuropathy after blunt head injury.
Four patients who developed immediate blindness (no light perception) after indirect traumatic optic neuropathy caused by blunt head injury recovered vision without surgical intervention. In one patient, whose affected eye recovered to a visual acuity of 20/50 + 2, corticosteroids were not used. In two of the other patients, visual recovery began before corticosteroids were instituted. One patient recovered a visual acuity of R.E.: 20/15, one recovered a visual acuity of L.E.: 20/25-2, and one recovered a visual acuity of R.E.: 20/200 but with useful temporal field vision. Many investigators advocate aggressive surgical therapy for indirect neuropathy, particularly when corticosteroids fail. Significant recovery may occur despite no light perception, however, with medical therapy or even without therapy.
