Objective To observe the therapeutic effects of vitrectomy combined with tissue plasminogen activator(r-tPA) and fraxiparine on bacterial endophthalmitis. Methods Forty pigmented rabbits were randomly divided into experimental and control group with 20 rabbits in each. The left eyes underwent intra-vitreous injection with 10 5/ml bacteria of staphylococcus epidermidis 0.1 ml. After 8-4 hours, vitrectomy was performed on all of the animals. Fraxiparine with the final concentration of 6 IU/ml was only added to balanced salt solution in the experimental group during the operation, and the extend of intraocular fibrin exudation was observed by slit lamp and indirect ophthalmoscope after the operation. If the exudation occurred on the 1st, 3rd, 7th, 14th and 21st day postoperatively, 125 mg/ml r-tPA 0.1 ml should be injected into vitreous from the 1st day after operation on. Results Fibrin exudation in the pupil area and vitreous body was much less in experimental group than that in the control group after the surgery. Conclusion vitrectomy combined with r-tPA and fraxiparine may alleviate the extent of fibrosis in bacterial endophthalmitis and improve the prognosis.  (Chin J Ocul Fundus Dis, 2005, 21: 391-393)
