Indirect optic nerve injury as traumatic loss of vision may occur without external or internal evidence of injury the eye or its nerve.The optic nerve is injured in 0． 5％ to 1． 5％ of cases of closed head injury and often involve the optic canal.Common injuries resulting in traumatic optic neuropathy(TON)include a blow to the ipsilateral brow or forehead, most often as a result of a motor vehicle or bicycle accident, fall, or assault.Advances in endoscopic instrumentation and surgical techniques have made endoscopic optic nerve decompression via an intranasal transethmoidal-transsphenoidala preferred approach over other extracranial or craniotomy approaches.After the endoscopic intranasal optic nerve decompression made a direct and easy approach possible, it became more popular and optic nerve pathologies attracted more interest among ENT surgeons.Surgical decompression may be performed for numerous lesions that compress the optic nerve in the optic canal leading to problems with vision.However, it is most often most controversially employed for decompression in indirect traumatic injuries to the optic nerve.The role of surgical decompression is not clear, with a lack of controlled studies in the literature.The problem to resolve the issues was slow enrollment.Our experience showed that EOND is beneficial in selected traumatic caes and in certain pathologies.The decisions regarding the patients who should be operated and the type of intervention to use should be made after considering all patient-specific factors while weighing risk versus potential benefit.
