Many patients will say, “Doctor, how can I treat my fundus bleeding? In fact, fundus bleeding is a symptom, not a disease, and I will have to examine you in detail to confirm which disease is causing the bleeding before I can give you a treatment plan. Just like a cough is not a disease per se, it is a symptom that is caused by a cold, pneumonia, tuberculosis, etc. I have told my subordinate doctors many times about fundus hemorrhage that they must make it clear to the patient that fundus hemorrhage is a sign and must let the patient really know what kind of disease he or she is suffering from. Classification of fundus hemorrhage: Fundus hemorrhage is divided into vitreous hemorrhage, preretinal hemorrhage, intraretinal hemorrhage and subretinal hemorrhage, each of which hides one or more diseases behind it. Common diseases that cause fundus hemorrhage: severe diabetic retinopathy, hypertension, retinal vein obstruction, perivenous inflammation, trauma, age-related macular degeneration, high myopia, vitreous traction, etc. Diabetes, hypertension, inflammation, and trauma can cause vitreous cavity hemorrhage, preretinal and intraretinal hemorrhage, and rarely result in subretinal hemorrhage. Macular degeneration and high myopia usually cause subretinal hemorrhage and relatively rarely cause other types of hemorrhage. Treatment of fundus hemorrhage: Many patients with fundus hemorrhage have used blood-stasis activating drugs for a long time without effect or worse, and of course a few patients feel better. People’s own repair ability is very strong, just like a cut by a knife, it will heal itself without treatment.
