Abstract

PURPOSE
To evaluate the effect of high dose corticosteroid and optic canal decompression on the traumatic optic nerve injury. METHODS: Twenty six patients who were diagnosed to have traumatic optic nerve injury, were divided into two groups in which one group received corticosteroid therapy while the other group underwent optic canal decompression combined with corticosteroid therapy. RESULTS: Visual acuity increased by > OR =3 lines of LogMAR scale in 47% of the corticosteroid group, in 28% of operation and steroid group, and in 42% of overall cases. But the degree of visual acuity improvement had no difference between two groups(p=0.72). As the patients were divided into two groups based on initial visual acuity such as no light perception and light perception or better, the initial visual acuity did not have influence on the final visual outcome in both corticosteroid group and operation and steroid group(p=0.78, p=0.33). CONCLUSIONS: This result suggest that effect of high dose corticosteroid and optic canal decompression on traumatic optic nerve injury is not different.
