Abstract: in addition to the general changes of high myopia such as leopard shaped fundus, posterior scleral staphyloma and map atrophy of retinal pigment epithelium, small patchy bleeding can be seen in the macular region of patients with macular hemorrhage in high myopia.
macular lesions are very harmful to the eyes. In high myopia, the probability of high myopia macular disease is relatively high. People with high myopia should pay attention to it.
with the development of society, high myopia is also gradually increasing. The average prevalence of high myopia in China is about 1%. In particular, macular lesions caused by high myopia have gradually become one of the main causes of low vision or blindness. The main cause of blindness is the progressive extension of ocular axis, retinal choroidal degeneration or other ocular organic diseases.
“high myopia maculopathy” popular science time
high myopia maculopathy includes macular hemorrhage, atrophy, paint like crack (crack in Bruch membrane) and Fuchs macula, among which macular hemorrhage is of particular concern. We call the high myopia macular hemorrhage with choroidal neovascularization as neovascular high myopia macular hemorrhage, and the high myopia macular hemorrhage related to the formation of new paint cracks as paint crack macular hemorrhage or simple macular hemorrhage.
patients with macular hemorrhage in high myopia can see small patchy hemorrhage in the macular area except for the general changes of high myopia such as leopard shaped fundus, posterior scleral staphyloma and map atrophy of retinal pigment epithelium. Although the mechanisms of the two types of bleeding are different, because the bleeding is located in the macular area, it will have a serious impact on the patient’s central vision, such as dark shadow, dark spot or visual deformation.
simple macular hemorrhage has a good visual prognosis. After taking drugs and bleeding absorption, the visual acuity can be recovered to varying degrees. However, if the paint crack just passes through the macular fovea, the visual acuity is obviously affected. For neovascular macular hemorrhage, although its activity is low, choroidal neovascularization is often located in the macular fovea or adjacent fovea; And with the extension of time, chorioretinal atrophy gradually expanded, so that the visual prognosis is often poor. In order to avoid such progressive visual impairment, it is necessary to take appropriate clinical treatment measures.
in high myopia, the probability of high myopia macular disease is relatively high. It should attract the attention of high myopia. Drugs are generally used to promote blood circulation and remove blood stasis for high myopia macular hemorrhage. According to fluorescein fundus angiography and other diagnostic methods, determine whether there is choroidal neovascularization. If there is neovascularization, intravitreal injection of anti neovascularization drugs (leizumab, etc.), laser treatment, surgical removal of neovascularization membrane, macular transposition, etc. can be considered according to the specific pathological conditions of the patient.
