We treated 2 patients for traumatic optic neuropathy. Visual acuity remained unchanged following high-dose corticosteroid therapy in both patients. They underwent optic nerve decompression under endoscopic control. One patient with preoperative visual acuity of 0.01 showed an improvement of visual acuity and expansion of visual field. The other was blind preoperatively and did not show any improvement postoperatively. Other authors reported that improvement of vision occurred in approximately half the patients who had no light perception prior to surgery. Therefore, optic nerve decompression can be an option in the treatment of traumatic optic neuropathy, if vision worsens or remains unchanged even after the patient is treated with high-dose corticosteroid therapy.
Key words : endoscopic, optic nerve decompression, traumatic optic neuropathy, visual acuity
