【摘要】 目的 通过动物试验观察苏拉明复合粘弹剂与5-氟尿嘧啶(5-Fu)眼内灌注对大鼠后发性白内障的影响。方法 30只健康大鼠制作白内障大鼠模型, 随机分成空白对照组、苏拉明组、5-Fu组, 每组10只。行超声乳化白内障吸除术, 术中分别应用普通粘弹剂、浓度为300 μg/ml苏拉明复合粘弹剂及浓度为0.2 mg/ml的5-Fu, 观察术后大鼠后囊膜混浊情况。结果 苏拉明复合粘弹剂及5-Fu均能对鼠眼后发性白内障起到抑制作用, 但苏拉明的作用更确切、疗效更好, 长期效果更明显, 前房反应仅限于房闪(+), 且在术后第3天完全消失, 不会对眼部产生不良影响。术后第6个月, 苏拉明组后囊混浊眼发生率10%低于空白对照组60%及5-Fu组40%, 差异均有统计学意义(P<0.05)。结论 苏拉明复合粘弹剂较5-Fu能更好的预防后发性白内障。

【Abstract】 Objective To observe influence by suramin composite viscoelastic agent and 5-fluorouracil (5-Fu) through intraocular irrigation on rat posterior capsular opacification. Methods A total of 30 healthy rats as cataract rat model were randomly divided into blank control group, suramin group and 5-Fu group, with 10 rats in each group. They all received phacoemulsification, along with respectively applied normal viscoelastic agent, suramin composite viscoelastic agent by 300 μg/ml, and 5-Fu by 0.2 mg/ml. Postoperative posterior capsular opcaification condition was observed. Results Suramin composite viscoelastic agent and 5-Fu showed inhibiting effects on rat posterior capsular opacification, while suramin had more precise effect, better curative effect and more obvious long-term effect. Anterior chamber response was strictly limited as aqueous flare (+), which completely disappear in 3 d after operation, without any adverse effect on eyes. In postoperative 6 months, suramin group had lower incidence of eyes with posterior capsular opcaification as 10% than 60% in blank control group and 40% in 5-Fu group. Their differences all had statistical significance (P<0.05). Conclusion Suramin composite viscoelastic agent provides better prevention than 5-Fu for posterior capsular opacification.

白内障是我国第一大致盲性疾病, 目前, 我国白内障患者已经超过500万, 急需手术治疗的接近200万, 每年新增的白内障人数40万~60万。据不完全统计, 在60~69岁人群中约25.97%的人患白内障, 70~79岁为59.95%, >80岁为83.02%。超声乳化白内障吸除联合人工晶体植入术是主要治疗手段, 但有文献报道, 成年人白内障术后2年内有20.0%~30.0%的患者因后发性白内障而再度失明[1], 5年内有43.0%的患者因后发性白内障而需再次手术[2]。本实验通过术中应用普通粘弹剂、浓度为300 μg/ml苏拉明复合粘弹剂及浓度为0.2 mg/ml的5-Fu, 观察大鼠术后后囊膜混浊情况, 证实苏拉明对于鼠眼后发性白内障的产生有良好的预防作用。现报告如下。
