The mean age of the patients was 3.3\u2009\u00b1\u20091.7 years, where 57.1% were males. Scissors (28.6%, <jats:italic>n<\/jats:italic>\u2009=\u20096) were the most common cause of injury; 86.7% of patients were injured at home. Zone I (80.9%) was the most common wound site; 90.5% of patients presented with a traumatic cataract. In general, <jats:italic>Streptococcus pneumoniae<\/jats:italic> (47.6%) was the most common isolate. Viridans group streptococci accounted for 58.3% of cases in children aged 0\u20133 years, while <jats:italic>S. pneumoniae<\/jats:italic> accounted for 66.7% of cases in children aged 4\u20136 years. The susceptibility rates of streptococcus to cefuroxime, levofloxacin and ofloxacin were 100%, 95.0% and 90.5%, respectively. Although all the patients underwent vitrectomy combined with silicone oil tamponade, the final visual outcomes were no better than counting fingers.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>Although <jats:italic>S. pneumoniae<\/jats:italic> was the most prevalent organism in general, the dominant species varied between different age groups. The commonly used antibiotics, cefuroxime and fluoroquinolone, showed higher antibiotic susceptibility.
