Abstract
Out of 8 cases of optic nerve injury patients treated between 1971 to 1974, the most recent 4 cases underwent decompression with the optic nerve sheath incision and these cases proved to have good postoperative recovery.
1. Sheath incision contributed to the early recovery (within 7 days) of visual acuity in most cases.
2. All sheath incision cases recovered useful visual acuity (0.01 or better) postoperatively.
3. Sheath incision is apparently useful to improve visual acuity in patients who suffered edema or circulatory insufficiency of the nerve.
4. Sheath incision can be applied in cases of total blindness as shown in Case 8 of our series.
