Abstract:
Posterior staphyloma (PS) refers to the local abnormal bulge of the posterior wall of the eyeball, which is one of the common pathological changes in high myopia.The appearance of PS is often accompanied by changes in fundus microstructure such as sclera, choroid and Bruch membrane.The abnormality of fundus microstructure leads to the decrease of its resistance to the expansion of ocular axis, or causes the remodeling of tissue structure in the corresponding area, resulting in the change of microvascular structure, and then giving rise to abnormal blood circulation in the posterior pole.The microcirculatory changes may be followed by changes in fundus microstructure, seriously affecting the visual acuity of the affected eyes.There is still no clear conclusion on the pathogenesis of PS in the world, and there are no good preventive measures or treatment methods.This article reviewed and summarized the interaction between PS, fundus structure and microcirculation in high myopia, so as to provide a theoretical basis for exploring the pathogenesis, prevention and treatment of PS and improving the visual function of high myopia.
