Abstract:
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.
