Ocular Trauma in a Rural Population of North China:The Handan Eye Study

Funds:  This study was supported by the National Basic Research Program of China(973 Program)%grant 2007CB512201 from the Ministry of Science and Technology of the People’s Republic of China, the Program of Health Policy for Blindness Prevention from the Ministry of Health of the People’s Republic of China%The study was partially funded by the Key Technologies R&D Program. No.2006-10903 from the Bureau of Science and Technology of Handan City, Hebei Province, China%Additional support was provided from Beijing Tongren Hospital and a key discipline fund from the Bureau of Health, city of Handan, Hebei Province, China
  • Objective To determine the prevalence of ocular trauma and the proportion of blindness and visual impairment due to trauma in a rural population in northern China.
    Methods The Handan Eye Study is a population-based cross-sectional study that surveyed 6830 Chinese people aged 30+years from 13 randomly selected villages in Yongnian County, city of Handan, Hebei Province, in July, 2006. All participants underwent a standardized interview and extensive examinations. A structured questionnaire was used to collect information on ocular trauma.
    Results Of the 5837 participants who filled out the questionnaire, 124 subjects [2.1%;95%confidence interval (CI), 1.8%-2.5%] reported a history of ocular trauma in either eye, including 19 (0.3%) persons reporting trauma in both eyes. Men were more likely to have an eye injury than women [odds ratio (OR), 3.3;2.2-4.9]. In multiple logistic regression models, ocular trauma was significantly more frequent among normotensive participants when compared with hypertensive participants (hypertensive vs. normotensive:OR, 0.6;0.4-0.9) and among participants who had a history of falls (OR, 2.4;1.2-4.8). The proportion of unilateral visual impairment and unilateral blindness due to trauma were 10.5% (13 subjects) and 21.0%(26 subjects), respectively.
    Conclusion Our study reports the prevalence of severe ocular trauma among adults in rural China, revealing a high proportion of blindness and visual impairment due to trauma. These findings suggest the need for educational strategies to increase eye health awareness in this rural population with focus on providing at least appropriate first aid care to reduce blindness due to trauma.
