Abstract Background The aim of this study was to review the demographic and characteristic distribution data of serious rural pediatric eye injuries in Wenzhou and Changsha, located in Zhejiang Province in East China and Hunan Province in Central China. Methods This retrospective study included hospitalized pediatric patients aged < 18 years with eye injuries at the Eye Hospital of Wenzhou Medical University and Xiangya Hospital of Central South University from January 2008 to December 2017. Demographic data, injury types, injury causes, and initial and final visual acuity (VA) were recorded and analyzed. The ocular trauma score (OTS) was calculated to assess the severity of injury and evaluate the prognosis. All patient data were obtained from the medical record systems. Results In total, 1125 children were hospitalized during the 10-year period; 830 (73.8%) were males and 295 (26.2%) were females. The majority of the patients were aged 3 to 8 years (57.4%, n = 646). Among mechanical injuries (n = 1007), penetrating injury was the most common (68.4%, n = 689), followed by contusion (17.2%, n = 173) and rupture (8.1%, n = 82). Overall, the top three injury causes were sharp objects (n = 544, 48.4%), blunt objects (n = 209, 18.6%) and fireworks (n = 121, 10.8%). In Wenzhou, eye injuries occurred mostly in summer (n = 136, 29.1%), and sharp object-related eye injuries accounted for the highest proportion (n = 98, 72.1%). In Changsha, eye injuries occurred mostly in winter (n = 272, 41.3%), and firecracker- and fireworks-associated eye injury accounted for the highest proportion (n = 73, 26.8%). The final VA was positively correlated with the initial VA (r = 0.641, P < 0.001) and the OTS (r = 0.582, P < 0.001). Conclusion The age range of the susceptible pediatric population from rural areas was 3–8 years. Most eye injuries were penetrating, and the main cause of injury was a sharp object. Notably, the differences in the characteristics of eye injuries in the two areas were related to regional features.
