What reason is eyeground haemorrhage caused?

summary

Fundus hemorrhage is a kind of eye disease with sudden onset. Patients often have sudden darkness or blurred vision in front of their eyes, which is a very terrible thing and brings great pressure to life. And fundus hemorrhage is likely to be accompanied by retinal and macular diseases, and macular diseases are very complex eye diseases, which have a huge impact on the vision of patients. What reason is eyeground haemorrhage caused? Let's talk about it

What reason is eyeground haemorrhage caused?

Retinal vein occlusion: patients often have hypertension, arteriosclerosis history, clinical manifestations of sudden visual loss or blurred vision. Fundus examination showed a large number of flaky or flaming hemorrhage in the venous occlusion area, accompanied by retinal edema and exudation. If the branch retinal vein occlusion, fundus hemorrhage is generally limited to the local area of vein occlusion, central retinal vein occlusion, fundus hemorrhage is extensive and serious. Branch retinal vein occlusion involves macular area or central retinal vein occlusion, and patients may have significant visual loss.

Diabetic retinopathy: Patients with a history of diabetes, some diabetic patients do not know, blood glucose test can be a clear diagnosis. The fundus hemorrhage of diabetic retinopathy develops gradually. In the early stage, there was only a small amount of punctate hemorrhage with microangioma, and punctate hemorrhage and exudation could occur with the progression of the disease. At this time, most patients have no conscious symptoms. Once the lesions progress to the proliferative stage or macular edema occurs, the patients can show decreased vision. If retinal neovascularization leads to a large amount of pre retinal hemorrhage or vitreous hemorrhage, the patient usually has a sudden drop in vision, and only manual vision can be seen in severe cases.

Senile macular degeneration: the fundus hemorrhage site of senile wet macular degeneration is generally limited in the macular area, and the age of patients is more than 50 years old. The clinical manifestations were sudden visual loss, mainly central visual impairment. Subretinal neovascularization membrane (CNV) in macular area could be found by Oct. In the late stage of wet macular degeneration, large area of subretinal hemorrhage, even vitreous hemorrhage can occur, causing more serious visual impairment.
