What reason is macular hemorrhage of high myopia

Abstract: the pathological changes of high myopia mainly include vitreous degeneration, posterior scleral staphyloma, paint crack in macula, macular hemorrhage, Fuchs macula in macula, etc. Among them, macular hemorrhage in high myopia can be divided into simple type and neovascular type., High myopia refers to myopia with a diopter greater than -6.00d (600 degrees). It is a common eye disease. Because there are many pathological changes in the fundus of the eye, it is also called pathological myopia or degenerative myopia clinically. At present, the incidence of this disease is high in China. Especially among the educated population, the incidence rate of high myopia among the 5908 college entrance examination students is 42.2%. The pathological changes of high myopia mainly include vitreous degeneration, posterior scleral staphyloma, paint crack in macula, macular hemorrhage, Fuchs macula in macula, etc. Among them, macular hemorrhage in high myopia can be divided into simple type and neovascular type. Its pathogenesis is not very clear, and most scholars believe that it is related to the formation of paint cracks., In simple macular hemorrhage, that is, in the absence of choroidal neovascularization, Klein found that there could be bleeding before the occurrence of typical linear and white lacquer cracks. In 96% of cases, macular hemorrhage was related to lacquer like crack lesions. Most of the bleeding was distributed along lacquer like crack lesions, rarely near the cracks., In neovascular macular hemorrhage, lacquer crack is also closely related to the occurrence of choroidal neovascularization. Hotchkiss and fine found that the incidence of lacquer like crack lesions was higher in eyes with choroidal neovascularization than in eyes without choroidal neovascularization. Arila et al. Observed that 82% of eyes with choroidal neovascularization had lacquer like crack lesions. FFA showed that subretinal neovascularization membrane directly originated from or connected with lacquer like crack disease. Patients with myopia course of more than 20 years, ocular axis of more than 29mm, diopter of more than – 10d and posterior scleral staphyloma were prone to macular hemorrhage. Lacquer like crack was closely related to macular hemorrhage in high myopia., Macular hemorrhage in high myopia can be divided into the above two types. The prognosis of simple macular hemorrhage is good, and that of macular hemorrhage with srnv is poor. Regular examination of fundus and fundus fluorescein angiography (FFA) is helpful to early find srnv., The above is about how macular hemorrhage in high myopia is going on. Macular hemorrhage is one of the important complications of high myopia. It is more common in clinic and often leads to serious damage to central vision. Early detection and early treatment are very important.,

high myopia mainly include vitreous degeneration, posterior scleral staphyloma, paint crack in macula, macular hemorrhage, Fuchs macula in macula, etc. Among them, macular hemorrhage in high myopia can be divided into simple type and neovascular type. Its pathogenesis is not very clear, and most scholars believe that it is related to the formation of paint cracks.

in simple macular hemorrhage, that is, in the absence of choroidal neovascularization, Klein found that there could be bleeding before the occurrence of typical linear and white lacquer cracks. In 96% of cases, macular hemorrhage is related to lacquer crack lesions. Most of the bleeding is distributed along lacquer crack lesions, and rarely near the cracks.

in neovascular macular hemorrhage, lacquer cracks are also closely related to the occurrence of choroidal neovascularization.

macular hemorrhage in high myopia can be divided into the above two types. The prognosis of simple macular hemorrhage is good, and that of macular hemorrhage with srnv is poor. Regular examination of fundus and fundus fluorescein angiography (FFA) is helpful to early detection of srnv.

and

above are the introduction of what is going on with macular hemorrhage in high myopia. Macular hemorrhage is one of the important complications of high myopia. It is more common in clinic and often leads to serious damage to central vision. Early detection and early treatment are very important.
