Abstract: Background: Proliferative diabetic retinopathy is the most common complication of diabetes. Long-term high blood sugar damage to retinal blood vessels, including arteriosclerosis, tissue ischemia, hypoxia, compensatory neovascularization and other pathological changes. It is divided into non-proliferative period and proliferative period. Then the treatment is to control blood sugar and take medicine to treat it conservatively. When vision declines, eyeball changes and retinopathy reach a certain level, when surgery is particularly critical. Early surgical treatment is not enough. The late operation misses the opportunity, which affects the effect of surgical treatment and even aggravates the condition. At present, the timing of the operation is still controversial. It is necessary to study the clinical characteristic analysis of surgical opportunities for proliferative diabetic retinopathy. The research will explain the advantages and disadvantages and the research results. Research methods: Vitrectomy was performed on 66 patients (89 eyes) with PDR hospitalized from January 2020 to January 2023. During the operation, different surgical treatment methods were used according to the situation, so that the omentum was well restored. Patients were followed up after surgical treatment. This includes improvement in corrected vision after 3 months, 6 months, and 12 months, no improvement or decline in vision, and loss of eye vision. In the clinical study, the improvement of visual acuity in stage IV to V, the treatment of intraocular filling with silicone oil, etc. Statistical analysis and clinical characteristics were conducted based on the above data. Objective: To study and explore the clinical characteristics of surgical opportunities after retinopathy caused by diabetic complications. Results: Vitrectomy was performed on 66 patients (89 eyes) with PDR who were hospitalized between January 2020 and January 2023. During the operation, 15 eyes were treated with peeling membrane, 20 eyes were treated with retinal photocoagulation, 17 eyes were treated with gas-liquid exchange or heavy water injection, and 37 eyes were treated with C3F8 gas or silicone oil filling. Results After 3 months, 6 months and 12 months, 68 eyes were improved, 12 eyes were not improved or decreased, and 9 eyes were lost. Stage IV-V 65 eyes (stage V 31 eyes), stage VI 24 eyes. Postoperative visual acuity improved in 45 eyes in stage IV to V and 12 eyes in stage VI. 37 eyes filled with silicone oil. Stage IV to stage V 25 eyes, stage VI 12 eyes.
