Grading criteria for diabetic retinopathy

Diabetic retinopathy is one of the most common chronic complications of diabetes mellitus. The clinical stages are mainly divided into two major stages, one is called simple stage and the other is called proliferative stage. Each stage is divided into three small stages, so it is a total of six major stages. We often say six major stages. The first stage of simple stage is divided into three major stages. The early performance is mainly the formation of this microangioma, showing soft exudation, hard exudation, cotton wool spots and so on. In the proliferation phase, it shows the formation of a new blood vessel, even a vitreous hemorrhage, or even retinal detachment. once it shows new blood vessels, in the early stage, we mainly through drug treatment, it can even be partially reversed. once it shows the proliferation phase, it is difficult to actively reverse, it is difficult to reverse, the treatment method is mainly early application of laser therapy, that later stage may be treated through some surgery. Therefore, it is mainly divided into two major periods, each of which is divided into three small periods, totaling six periods.
