Due to high myopia, the eye becomes longer and larger, the wall of the eye becomes thinner, the choroid also becomes thinner, the original choroid has a large number of blood vessels become less, the supply of nutrients to the retinal blood is reduced, the retinal ischemia, lack of nutrients, it will secrete a “vascular growth factor”, vascular growth factor to promote the growth of new blood vessels. Since there is no retinal blood vessel in the macula of the retina, its nutrient supply is completely dependent on the choroid, and the macula is the most sensitive place to see things, which consumes the most nutrients and is most likely to cause ischemia, so the new blood vessels are most likely to grow under the retina in the macula. The growth of neovascularization is a good thing and a kind of compensation, but because the wall of neovascularization is very thin compared with normal blood vessels, with only one layer of cells, it is very easy to rupture and bleed, which is the macular hemorrhage area seen in the clinic. 1.What is the symptom of macular hemorrhage caused by myopia? If there is a lesion in macular area, there is often vision loss, black shadow in front of the eyes or distortion of visual objects. 2.How to treat macular hemorrhage due to myopia Simple macular hemorrhage has a good prognosis, and after the hemorrhage is absorbed by taking medication, vision is mostly restored to different degrees. However, if the lacquer-like crack happens to pass through the central macular recess, the vision is affected to some extent. As for neovascular macular hemorrhage, although its activity is low, the visual prognosis is often poorer because choroidal neovascularization is often located in or adjacent to the central macular recess; and choroidal retinal atrophy gradually expands with time, making the visual prognosis often poorer. To avoid such progressive visual impairment, it is necessary to take appropriate treatment measures in clinical practice. For highly myopic macular hemorrhage, medications are generally used to activate blood circulation and resolve blood stasis. The presence or absence of choroidal neovascularization is clarified by means of fluorescein fundus angiography and other diagnostic tools. If there is neovascularization, medication, laser treatment, surgical removal of neovascular membrane and macular transposition surgery can be considered according to the specific lesion of the patient. 3.How long can macular hemorrhage due to myopia recover Macular hemorrhage, if not much, can be absorbed in 2-3 months and most of them do not leave after-effects, if the amount is more, it can form paralysis marks, form Fuchs’ spot and leave permanent dark spot in the center of visual field. Since the neovascularization under the macula still exists, the root cause of bleeding still exists, and the neovascularization keeps rupture, forming repeated bleeding, repeated bleeding is very easy to form scars, leading to permanent vision loss. 4.Does macular hemorrhage caused by myopia need hospitalization? For macular hemorrhage caused by high myopia, drugs are generally used to activate blood circulation and resolve blood stasis. The presence or absence of choroidal neovascularization can be clarified by fluorescein fundus angiography and other diagnostic means. If there is neovascularization, medication, laser treatment, surgical removal of neovascular membrane and macular transposition surgery can be considered according to the patient’s specific lesion. Some treatments require hospitalization, depending on the needs of the condition.
