摘　　要：作者通过动物实验,澄清兔眼碱烧伤后各时期眼压的反应,并研究了与眼压反应有关的机制.结果:碱烧伤后眼压最高峰值于烧伤即刻～1小时,2周后眼压开始回落,30大～6个月眼压平稳.前房角组织结构早期以排出途径突发性阻塞为主要病理改变,中期则表现为组织的胶原纤维增生,小梁网孔开大与狭窄并存,房水排出系统阻力减小.晚期以睫状体纤维山及萎缩为主要病变.By the experiment study with rabbit, the authors clarified IOP changes for various periods after alkaline burn and studied the mechanism related to IOP changes. The results showed: the peak of the IOP was between burning instant and one hour after burn,began to come down after two weeks and come back to normal between one and 6 months. The main pathological changes were instant block of exit path at first,collagen fibro byperpiasia,wide and narrow hole in trabeculum si-multaneouly and reducing of aqueous exit obstruction in the middle of time, and fibrosis and atrophy of ciliary body in the late. This suggestes that IOP should be con-troled within two weeks.
