摘要 目的建立单眼视觉剥夺性弱视大鼠模型,观察其视网膜组织中Bcl-2/Bax及Caspase-3的表达变化,探讨弱视的发病机制。方法新生Wistar大鼠20只,雌雄不限。1周龄时,应用褥式缝合法缝合大鼠单侧眼睑,建立动物模型。采用自体对照,缝合眼为模型组,另一眼为正常组。6周后处死所有大鼠,摘取眼球。HE染色观察视网膜形态学变化;应用免疫组化法检测Bcl-2、Bax及Caspase-3在视网膜组织中的表达。结果与正常组相比,模型组视网膜形态异常,Bax及Caspase-3的表达明显增强(P<0.05),Bcl-2的表达明显减弱(P<0.05)。结论单眼视觉剥夺性弱视的发病机制可能与视网膜组织中Bcl-2表达下调和Bax及Caspase-3表达上调有关。
