AIM: To provide the basis of security guidance and decreasing the incidence through a general investigation of the mechanical ocular trauma among all the common causes, occasions where getting hurt as well as the characteristics of the high-risk group, and by further analysis and monitoring of the clinical cases and follow-up visit, study the related key factors of influencing the prognosis statistically.

METHODS: The data of the 159 cases with mechanical ocular trauma were recorded.

RESULTS: We obtained the 159 subjects' ages, genders as well as mechanical ocular trauma characteristic data, such as ocular distributions, the seasons of the injuries occurring, the causes and the occasions of the injuries, the high-risks group and so on. The factors affecting the visual prognosis,univariate analysis showed that the difference between urban and rural areas was a related influencing factor while the consulting hours and the ages of the patients were irrelevant. In the multivariate Logistic regression model of complications that affected the visual prognosis, there were four main factors leading to poor eyesight: endophthalmitis, retinal detachment, luxation or subluxation of the lens, prolapse of vitreous. In the multivariate Logistic regression model of the visual prognosis of mechanical eye injury, there were three factors of concern that corresponded to poor eyesight: the ages less than 10, zonation Ⅲ, grade of injury more than 3.

CONCLUSION: The epidemiologic features of the mechanical ocular trauma in our hospital correspond to the reports from other areas. Appropriate medical care can improve the visual prognosis. Factors such as zonation Ⅲ, ages less than 10, grade of injury more than 3, endophthalmitis with the eye injury, prolapse of vitreous, luxation or subluxation of the lens and so on, indicate poor visual prognosis.
