Abstract:
Objective To analysis the cause of injury of traumatic optic neuropathy and explore the main factors affecting the prognosis of visual acuity. Methods We retrospectively collected clinical data of 104 cases (108) of traumat-ic optic neuropathy from January 2007 to December 2012 in the Renhe Hospital of Three Gorges University. We then ex-amined the cause of injury and analyzed risk factors for poor prognosis of visual acuity in traumatic optic neuropathy us-ing multivariate Logistic regression analysis. Results The mean age of patients was 33.6 ± 12.8 years and 95 cases (91.3%) were males. The injury was mainly caused by non-motor vehicle and motor vehicle accidents (84 cases, 80.8%). Most of the patients came to the hospital within 3 days after the injury (81 cases, 77.9%). Overall efficacy rate of treat-ment was 45.4%(49/108). The effective rate was 29.9%(20/67) for visual acuity without light perception and 70.7%(29/41) for visual acuity with light perception, respectively. Logistic regression analysis showed that the time to treatment≥24h, orbital hemorrhage or orbital fracture, ethmoid or sphenoid sinus bleeding and no light perception vision were an in-dependent prognostic factors. Conclusion Time to treatment time and severity of injury are the independent risk factors for poor visual prognosis of traumatic optic neuropathy whereas controlling these risk factors has important clinical signifi-cance to the treatment and prognosis of traumatic optic neuropathy.
