Follow-up diabetic retinopathy (DR) simple type, period 85 cases 145 eyes. In the patients with proliferative diabetic retinopathy (PDR), the follow-up was 21 eyes (14%) in 2 years and 49 eyes (34%) in 5 years. The incidence, progression, Period> period, the difference was significant (P <0. 05). Diabetic macular edema increased with the increase of the follow-up period, with 35 newly diagnosed macular edema, increased to 43 eyes in 2 years and increased to 55 in 5 years. Beretinal retinal vein changes, a large number of intravascular retinal abnormalities and four quadrants of bleeding and / or microvascular tumor is a simple type of progression to PDR risk of disease. Poor glycemic control, long duration of diabetes and hypertension may be simple risk factors for progression to PDR. To prevent or reduce DR blinding, DR should be found early and given long-term follow-up
