Causes of hemorrhage in the fundus of the eye can be long-term smoking and drinking, taking medications, eye diseases, long-term diabetes and high blood pressure, and trauma. People with bad lifestyle habits such as long-term smoking and drinking have decreased elasticity of the blood vessels in the fundus, which can lead to rupture and bleeding of the blood vessels in the fundus when the blood pressure increases. Adverse reactions to some medications may also lead to bleeding in the fundus, such as heparin or coumarin anticoagulant drugs whose side effects include bleeding in the fundus. Diseases of the eye such as retinal hemangioma, retinal arteriovenous occlusion, and many other diseases of the fundus can lead to rupture of blood vessels in the fundus. When you have long-term diabetes and high blood pressure, the elasticity of the blood vessels in the fundus decreases, and fluctuations in blood pressure can also cause bleeding in the fundus. When the eye is injured by trauma, sometimes there will be hemorrhage in the fundus, and there can also be vision loss, blurring, eye pain and other symptoms. When symptoms of fundus hemorrhage occur, you should go to the hospital and consult a doctor for help.
