Myopia greater than 600 degrees is considered high myopia, and its fundus is often combined with pathological changes, including scleral thinning, choroidal atrophy thinning and growth of the eye axis, also known as pathological myopia, which is very dangerous and often leads to poor vision and even blindness. Pathological myopia often has a myopic arc, leopard’s-eye fundus, and high myopia is often combined with posterior scleral staphyloma, lacrimation, Fuchs’ spots, choroidal atrophy, choroidal neovascularization, macular hemorrhage, and other changes. Among them, choroidal neovascularization and macular hemorrhage caused by lacrimal crack formation are the most common factors leading to severe vision loss. Fluorescein fundus angiography (FFA) can provide insight into changes in the retinal pigment epithelium and retinal blood circulation, and indocyanine green angiography (ICGA) can clarify the choroidal vascular structure and pathological changes in the choroidal circulation. Therefore, simultaneous examination of FFA and ICGA can provide a more comprehensive view of the pathological changes in various tissues of the fundus of patients with high myopia and help to detect lacunar fissures as well as CNV, which can help to understand the condition comprehensively and guide clinical treatment and prognosis. The treatment of pathological myopia is mainly aimed at its complications, such as retinal fissures, retinal detachment, and secondary macular neovascularization. Currently, we are carrying out vitreous cavity injection treatment for pathological myopia secondary to macular choroidal neovascularization, and a one-year free examination and treatment is available for those who meet the requirements for subject entry.
