Objective The burden and pattern of ocular trauma in China are poorly known and not well studied. We aimed at studying the epidemiological characteristics of patients hospitalized for ocular trauma in the largest industrial base of plastic toys in China.
Methods A retrospective study of ocular trauma cases admitted to three tertiary hospitals in China from January 2001 to December 2010 was performed. The extracted patient data included demographic information, date and cause of injury, the initial and final best-corrected ( Snellen ) visual acuity, the clinical diagnosis, the primary and secondary treatments, the duration of hospitalization and follow up. The injuries were classified according to the Ocular Trauma Classification System ( OTCS ) and the Birmingham Eye Trauma Terminology ( BETT ).
Results The study included a total of 3644 injured eyes from 3559 patients over the 10-year period: 2008 ( 55.1% ) open globe injuries, 1580 ( 43.4% ) closed globe injuries, 41 ( 1.1% ) chemical injuries, 15 ( 0.4% ) thermal injuries and 678 ( 18.6% ) ocular adnexal injuries. Based on national population census data, the average annual hospitalization rate due to eye injuries for our health district was 27.7 per 100,000 ( 95% CI, 26.4~28.9 ). The mean age of the patients was 29.0±16.8 years with a male-to-female ratio of 5.2:1 ( P = 0.007 ). The most frequent types of injury were work-related injuries (1656, 46.5%) and home-related injuries ( 715, 20.1% ). A total of 839 ( 23.6% ) eye injuries occurred in children aged 14 years or less due to the highly industrial nature. The initial visual acuity was correlated with the final visual acuity (Spearmans correlation coefficient = 0.659; P < 0.001 ). The OTCS diagnosis was also correlated with the final visual acuity ( Spearmans correlation coefficient = 0.655; P < 0.001 ).
Conclusions This analysis provides an epidemiological study of patients who were hospitalized for ocular trauma. Workers and children were the primary at-risk groups in this region. These data may be representative of any of the surrounding coastal industrial regions.
