summary

Many friends have a certain understanding of diabetes, and diabetes is not so terrible, the real terrible is the complications of diabetes. Eye disease is one of the complications of diabetes. So, what are the clinical manifestations of diabetic retinopathy?

Symptoms of diabetic retinopathy

Microangiomas, dark red hemangiomas with large needle cap are mostly located in the deep part around the macula, which can not regress for several months or adults. Similar hemangiomas often exist on the conjunctiva. Exudates often appear in the deep layer of the posterior pole of the retina. The shape is mostly small dots, gathered in piles, or edge clear, sometimes mixed with shiny cholesterol crystals, and accompanied by edema.

Venous changes are more common in young patients with severe diabetes. The tortuous expansion and neovascularization of the vein begin with a certain section of the main vein dilating in sausage or curl shape, and then most of the neovascularization appears in or near the optic papilla, which is fascicular or reticular, and can also extend into the vitreous body with hyaline membrane. After the rupture of such neovascularization, massive hemorrhage may occur and proliferative retinopathy may be formed, Finally, he became blind due to bloody glaucoma or retinal detachment.

Diabetic retinopathy is caused by diabetes. In addition to the general symptoms of polydipsia, polyuria, hyperglycemia and hyperglycemia, there are bright red capillary hemangioma and flaming hemorrhage in the retina of both eyes. In the later stage, there are gray white exudation, bright red neovascularization and fundus changes characterized by vitreous hematocele, It is significant for diagnosis and prognosis. The longer the age, the longer the course of disease, the higher the incidence rate of fundus.
