Methods The chronic ocular hypertention rat model was made by cauterizating three episcleral veins.Rats were divided into control group,high level PROG group,middle level PROG group,low level PROG group according to different concentrations of PROG injected intraperitoneally.The left eye was model eye and the right eye was control eye.Three months later,the animals were executed and the eyeballs were enucleated.The RGCs were detected by HE staining and Thy-1.1 immunohistological staining.

通过烧灼3条巩膜上静脉制作慢性高眼压动物模型，此模型按腹腔注射不同浓度的孕酮而分为高、中、低浓度孕酮注射组及空白对照组，左眼为模型眼，右眼为自身对照眼，3个月后处死动物，取眼球制石蜡切片，行HE染色、Thy-1.1免疫组化染色及TUNEL原位凋亡检测。
