Background: Traumatic optic neuropathy (TON) can be caused by direct or indirect injury. Direct optic injury usually results from optic nerve avulsion or laceration, or from direct fracture of the optic canal. Indirect optic injury is caused by increased intracanalicular pressure after an injury. The prognosis of direct optic injury is usually quite poor. To date, no standardized treatment protocol has been developed for TON. In this study we are assessing the visual improvement in patients with direct TON who underwent endoscopic optic nerve decompression in the last 10 years. Methods: 32 cases of optic nerve decompression for direct TON were done in the last 10 years. Preoperative and post operative visual assessment were done and followed up for 3 months, Results: There was complete improvement in vision in 59% of patients when optic nerve decompression was done within 72 hours of trauma; whereas 31% cases had partial improvement when done between 3 and 7 days. And there was 0% improvement when done after 7 days. Conclusion: Endoscopic optic nerve decompression is a minimally invasive effective method in direct traumatic optic neuropathy with minimal or no complications when done by well experienced ENT surgeon with ample knowledge of anatomy and anatomical variations. Other important prognostic factors include timing of surgery, extend of trauma and preoperative visual status Key words: Endoscopic optic nerve decompression (EOND), Nerve sheah incision/ fenestration, Traumatic optic neuropathy (TON), Visual assessment( VA), Visual improvement scale (VIS)
