摘　　要：眼压急进性升高是急性闭角型青光眼的典型表现,也是导致青光眼患者眼部组织损伤,视力下降甚至失明的重要原因。急性闭角型青光眼的短时间内眼压急剧地升高,会对视网膜、脉络膜以及视神经的结构和功能造成特征性的损伤。目前对于青光眼的诊断及病程评估,很大程度上是依赖于高眼压的状态,视神经的变化及视野的损伤,但此时青光眼患者的眼底已经发生了不可逆性的损伤。而眼后节的微结构改变,对于高眼压更加敏感,往往出现在视神经和视野损伤之前,可以更早的提示高眼压对眼部的损伤。通过对眼后节影像学特点的评估,可以从中探索出临床上评估影响青光眼预后的形态学特征,对于青光眼的早期诊断具有重要的临床意义。Rapidly increasing intraocular pressure(IOP)is a typical manifestation of acute angle-closure glaucoma and an important cause of ocular tissue damage,vision loss and even blindness in glaucoma patients.The sharp increase of intraocular pressure in a short period of time in acute angle-closure glaucoma will cause characteristic damage to the structure and function of retina,choroid and optic nerve.Currently,the diagnosis and evaluation of the course of glaucoma is largely dependent on the state of high IOP,changes in the optic nerve and visual field damage,but irreversible damage to the fundus has already been made in glaucoma patients by this time.The microstructural changes in the posterior segment of the eye are more sensitive to high IOP and often appear before optic nerve and visual field damage,which can indicate the damage of high IOP to the eye earlier.Through the evaluation of the imaging characteristics of the posterior segment of the eye,the morphological characteristics that affect the prognosis of glaucoma can be explored,which is clinically important for the early diagnosis of glaucoma.
