OBJECTIVE To analyse the bacterial culture of aqueous vitreous as well as their sensitivity to antibiotics in intraocular foreign bodies(IOFB).METHODS Bacterial culture of aqueous vitreous as well as their sensitivity to antibiotics were taken at 32 cases(32 eyes) of IOFBs with in 24 hours.And the results were analyzed.RESULTS 21 cases with bacterial culture of aqueous vitreous were found to be positive with bacterial infection.Staphylococcus epidermidis was the most frequently bacteria and identified in 15 cases,which accounted for 71.4% of these 21 cases.All the identified bacteria were sensitive to Ofloxacin,Ciprofloxacin and Cefoperazone,and partly sensitive to Gentamycin and Tobramycin.All of them were resistant to Chlororamphenicol and Rifapine.The occurrence of positive bacterial identification of unmetal foreign bodies were significantly higher than that of metal foreign bodies(?2=4.631,P=0.029).There was no significomt difference between.The location of penetrating eye trauma or lens rupture in the bacterial positive rate identification(?2=2.398,P=0.122;?2=0.327,P=0.568).CONCLUSIONS In patients with IOFB,the major bacteria entering into the eye was Staphylococcus epidermidis.As for prophylactic antibiotics,Quinolones and Cefoperazone can be used as the first line antibiotics.
