摘要目的观察组织型纤溶酶原激活剂(tissue plasminogen activator,t-PA)、肝素和高三尖杉酯碱联合用药对术后增生性玻璃体视网膜病变(proliferative vitreoretinopathy,PVR)的抑制效果。方法 43例44只眼接受玻璃体视网膜手术的复杂性视网膜脱离患者，根据手术及是否同时球内联合用药分为A、B两组(A组为用药组，B组为对照组)。随访观察两组术后PVR再发生及视网膜脱离复发情况，平均随访期为7．9个月。结果 PVR发生率：A组15.8%，B组45.5%，χ2检验，P＜0.05。视网膜脱离复发率A组5.5%，B组33.3%，χ2检验，P＜0.05。结论手术辅以球内联合用药可有效抑制术后PVR再形成，降低视网膜脱离复发率。

abstractsObjective　To observe the suppressive effect of combination of tissue plasminogen activator(t-PA）,heparin and homoharringtonine on the formation of proliferative vitreoretinopathy (PVR) after vitreoretinal surgery.　Methods　Forty-three cases (44 eyes)of complicated retinal detachment who received vitreoretinal surgery were divided into 2 groups.Twenty cases(20 eyes)in group A were treated by intravitreal injection of above mentioned drugs at the end of operation,while no intraocular injection of drugs given in 23cases(24 eyes)in group B.The mean follow-up period was 7.9 months.　Result　The rate of recurrent PVR in group A was 15.8%(3 of 19),and 45.5%(10 of 22) in group B　(P＜0.05).The rate of recurrent retinal detachment was 5.5%(1 of 18) in group A,and 33.3%(7 of 21)　in group　B，in group B　(P＜0.05).　Conclusion　Combination use of the above mentioned drugs can effectively suppress the postoperative recurrent PVR and lower the rate of subsequent recurrent retinal detachment.
