Is diabetic eyesight decreased symptom?
1. The main cause of vision loss in diabetic patients is retinopathy. Diabetic retinopathy is the most common microvascular complication in patients with diabetes mellitus. 80% of patients with type 1 diabetes mellitus will have retinopathy 15 years after onset. About half of the patients with type 2 diabetes will have different degrees of retinopathy when the course of disease is more than 10 years; When the course of disease was more than 15 years, the proportion gradually increased to more than 80%.
2. Diabetic retinopathy is mainly divided into two stages, namely non proliferative and proliferative retinopathy. Nonproliferative retinopathy (NPR) is the early stage of diabetes affecting the retina, and it is also the most common cause of visual impairment in patients with type 2 diabetes.
3. At this stage, microangioma, hemorrhage and exudation appeared in the retina. If the oozing blood is just in front of the macula, blocking the image of the object, it will lead to blurred vision. At this time, diabetics will feel a piece of red or black floating object in front of their eyes. With the absorption of fundus hemorrhage, the color of the floating object will become lighter, and the symptoms of blurred vision will be improved.
