Abstract´╝Ü Evidence-based guidelines for diagnosis and treatment of diabetic retinopathy in China (2022) is based on evidences in recent clinical trials and a system of Grading of Recommendations, Assessment, Development and Evaluation of evidence quality and strength of recommendations. The main key points around why the diabetic macular edema (DME) changes the classification, what thresholds for initiating anti-vascular endothelial growth factor (VEGF) drug therapy; eyes with center-involved DME (CI-DME) and good vision for clinical significant macular edema still treated by focal laser even with good vision, the clinical pathway for CI-DME changes first-line treatment from laser to anti-VEGF, loading dose of anti-VEGF for CI-DME in non-proliferative diabetic retinopathy (DR) from 3 injections up to 4-5 injections is recommended; severe non-proliferative DR and proliferative DR with vision impairment but without hemorrhages and retinal traction could be considered first treatment of anti-VEGF comparing to initiate pan-retinal photocoagulation (PRP) (weakly recommended), PRP is still gold-standard for progressive non-perfusion area of retina. With the rapid development of DR evaluation devices such as optical coherence tomography, wide-angle optical coherence tomography angiography and wide-angle fluorescein fundus angiography, imaging biomarkers have been provided for the degree of DR lesion, treatment response and prognosis. It is believed that the clinical practice will be promoted a new height by the 2022 edition of Chinese DR guideline.
