In the clinic, many patients have fundus hemorrhage or vitreous hemorrhage that causes vision loss, black shadows in front of the eyes, blurred vision, and hazy-like symptoms, which greatly reduces the quality of life of patients and even causes great fear in patients. Patients seek medical help everywhere, spending a lot of money, running a lot, the effect is poor, and even some patients are deceived to delay the disease. So how to diagnose and treat this situation? Experts combine their clinical experience and theoretical knowledge to give patients a scientific and simple clarification. I hope patients can get some inspiration from it! The first thing to figure out the bleeding cause mechanism In fact, fundus bleeding or vitreous hemorrhage is only a clinical sign, to know the causes of bleeding many, that is to say, many causes, so must be diagnosed clearly, in order to talk about treatment targeted, otherwise all treatment is not very scientific or blind, a waste of financial resources, energy and ultimately delay the disease! When you have a bleeding situation, no matter which hospital you go to, you must ask what causes your bleeding after seeing the doctor. Common causes are: 1, bleeding caused by trauma: this bleeding is often used to stop bleeding and activate blood stasis can be. Due to external forces acting on the tissue, causing local damage to the tissue vessels, when this damage is repaired the blood vessels will not bleed again. Treatment with coagulation, hemostasis, and blood circulation and stasis activation will often achieve good results. When there is a lot of bleeding, the use of vitreous surgery can be very effective! “This treatment is often carried out as a routine to treat fundus bleeding”, the fact is that fundus bleeding or vitreous cavity bleeding is not only caused by trauma, it has many other causes, it is necessary to distinguish other causes of fundus bleeding, otherwise the treatment is likely to be less than ideal! 2, abnormal coagulation mechanism bleeding problem: If the bleeding is caused by the lack of coagulation factors or the low number of platelets, the corresponding treatment should be carried out, such as supplementation of platelets or coagulation factors, which requires contact with the relevant hematology department for the corresponding treatment, to do the right thing! 3, vascular inflammation caused by bleeding: this is often due to inflammation, causing vasodilatation to increase vascular permeability resulting in intravascular component leakage caused by bleeding, the treatment at this time need to eliminate inflammation to reduce vascular permeability to reduce bleeding, to achieve the purpose of treatment of bleeding. 4, diabetes, venous obstruction, Coat’s, AMD (age-related macular degeneration), mid-bleed, perivenous inflammation caused by embolism and other such diseases caused by bleeding: due to retinal tissue vascular occlusion, resulting in tissue ischemia caused by tissue hypoxia, compensatory lead to (hypoxia caused by tissue) neovascularization. The most characteristic feature of this neovascularization is that it bleeds easily due to its unsoundness, and this bleeding is not due to the coagulation mechanism and local rupture of the blood vessels but due to the abnormality of the whole blood vessels. Therefore, conventional hemostatic therapy is obviously not targeted and can only treat the symptoms but not the root cause. Even if the patient’s vision improves a bit with treatment, the patient will bleed again in the future. The author has encountered many such patients in the clinic, after a long treatment bleeding old repeated, treatment slightly vision improvement soon after the original shape, vision loss again. This is mainly due to the lack of treatment of the cause! The most fundamental way to treat this kind of bleeding is to eliminate neovascularization. The most fundamental way to eliminate neovascularization is laser photocoagulation of the retina, the purpose of photocoagulation is to destroy the retinal tissue to reduce the amount of oxygen consumed by the tissue, while reducing its release of neovascular growth factors, to inhibit or eliminate the purpose of neovascularization! In fact, this treatment plays a role of “save the car and protect the marshal”. Of course, the current international more popular and for neovascularization of anti-VEGF factor drugs such as AVASTIN or LUCETIS vitreous cavity treatment, the author observed in the clinic found that although this treatment can eliminate neovascularization in the short term but soon neovascularization will reappear, need repeated injections to maintain the therapeutic effect. In clinical and daily life, especially in middle-aged and elderly people, retinal and vitreous cavity hemorrhage is mostly caused by neovascularization. Therefore, we must clarify the cause of our bleeding so that we can get a good treatment effect and the treatment of stopping bleeding and activating blood will not have a good effect in the end! Next, consider the treatment. After we analyze the mechanism of retinal and vitreous hemorrhage in detail above, it is easy to talk about the treatment. We can roughly divide the treatment into treating the symptoms and the root cause, that is to say, we take in the treatment process is to stop the boil or the bottom or both, that is to say, in clinical practice, the treatment in the end will be to treat the symptoms or the root cause or both the symptoms and the root cause. I think that through the above analysis, patients themselves can analyze – it is definitely both. Usually we use infusion or medicine to stop bleeding or blood treatment can only be regarded as the cure, in the clinic we also need scientific analysis to cure the root of the problem, such as trauma-induced bleeding by repairing the broken blood vessels as soon as possible, diabetic retinopathy by inhibiting the formation of new blood vessels, hematological bleeding cellular components of the body’s self-repair, etc. These are the root of the problem.
