| Objective: This paper compares the curative effect of endoscopic optic nerve decompression (EOND) and simple medical treatment and analyzes risk factors in traumatic optic neuropathy(TON).Methods: This paper retrospectively reviews patients with TON from August 1999 to January 2008. The 88 patients(88 eyes)with TON are divided into two groups : EOND (42 eyes)and drug(46eyes) andcurative effects of the two groups are compared. The best operationtime can be sought, based on the analysis of operations within or after 7 days since injures.This paper, regarding sex, age, eyes,visual acuity of no light perception(NLP), fracture, coma and injure reasonas independent variable (X), and the curative effects as dependent variable(Y), carries on nonconditional logistic regressionanalysis and studies the risk factors on traumatic optic neuropathy.Results:1. Among the patients with no light perception, there is statistic difference (p =0.044) between the surgical group and the drug group. The curative effect of operation is much better.2. Among the patients with light perception, the statistic difference between the two group (p =0.030). The effect of the surgery is better.3. According to the operation periods, there is difference (p = 0.029) between injured patients operated within 7 days and after 7days. It shows --the sooner, the better.4. Nonconditional logistic regression analysis( x~2=20.333, p =0.000)confirms that NLP ( p =0.010), coma ( p =0.010) are risk factors affecting traumatic optic neuropathy. Early surgical treatment after trauma could protect visual acuity in traumatic optic neuropathy (p =0.006).Conclusion:1. Therapeutic effect of surgical treatment, on patients both with and without light perception, is better than that of medicationtherapy.2. Therapeutic effect of Patients in operation within 7 days is better than that after 7 days.3. NLP, coma are risk factors affecting traumatic optic neuropathy. Early surgical treatment after trauma could effectively protectvisual acuity.
