[Conservative treatment of post-traumatic lesion of the optic nerve].

Twenty one patients aged 18-77 years with a lesion of the optic nerve caused by contusion of the head were treated conservatively in the period 1980-87. An improvement--often a substantial one--of the visual acuity was attained in 52.3 p.c. of patients; in 17 patients the vision did not deteriorate in the period of control examinations.
