Abstract

眼内压力升高 (IOP) 是青光眼的一个详细记录的危险因素。在这里,我们描述了一种在小鼠中持续诱导稳定的IOP高程的新方法,该方法模仿了在人类视网膜手术中使用硅油(SO)作为棉布剂的术后并发症。在此协议中,SO被注射到小鼠眼睛的前室,以阻止学生,防止水性幽默的流入。后室积累水性幽默,这反过来又增加了后段的IOP。单次SO注射可产生可靠、充足和稳定的IOP高程,从而诱发显著的青光眼神经退化。此模型是眼科诊所中继发性青光眼的真实复制。为了进一步模拟临床设置,SO 可以从前室中取出,以重开排水通道,并允许水性幽默的流入,水性幽默通过前室的角度通过眼网状工程 (TM) 排出。由于 IOP 很快恢复正常,该模型可用于测试降低 IOP 对青光眼视网膜性结条细胞的影响。该方法简单明了,不需要特殊设备或重复程序,密切模拟临床情况,可适用于多种动物物种。但是,可能需要稍作修改。
