AIM: To study the causes of ocular trauma and how it leads to blindness in children and to put forward preventive measures.

METHODS: Collect related data of 163 cases of ocular trauma(under 14 years old), including age, sex, vulnerant(causes of ocular trauma), ophthalmology, classification of ocular trauma and complications. And make a comparison of the visual acuity before and after treatment. OTS score is used to make an analysis of the correlation between the prognosis and the visual acuity.

RESULTS: The ratio of male to female is 3.79:1; the most common group lies on the school-age children(7-10 years old); the visit time is ≤24h. Closed ocular trauma is the most common one. Collision injury is the main cause with blunt trauma as major type. Most patients got injured in residential areas and nearby areas. The most common complications are anterior chamber hemorrhage and traumatic cataract. The visual acuity of admission is grouped based on whether it is ≥0.05 or not. There are differences in visit time, nature of trauma, complications,trauma type and surgery, among which complications are independent influencing factors \〖OR=2.708, 95%CI(1.285-5.705)\〗. After the treatment, the visual acuity is grouped based on whether it is improved or not. There are differences in gender, age, visit time, nature of trauma and complications among which gender, age and visit time are independent influencing factors. The OR value of visit time is 2.895, 95%CI(1.296-6.465).

CONCLUSION: Ocular trauma is one of the main causes leading to blindness in children. However, it is possible to reduce the occurrence of most ocular trauma by preventive measures.
