Chronic kidney disease(CKD)is a common chronic disease.There is homology between retina and kidneys.Diabetic retinopathy and retinal neurovascular injury both reveal common pathophysiological features of ocular retina and kidney.Optical coherence tomography angiography(OCTA)detects chorioretinal microcirculation with near-histological resolution.Changes in microvascular structure and function can promote the development of hypertension,diabetes,CKD and related cardiovascular disease(CVD).The examination of fundus nerve microvessels by OCTA in patients with CKD is helpful to the identification of high-risk groups,and provides a new perspective for the assessment of disease progression and CVD risk prediction of patients with CKD.The combination of the deep learning will further expand this aspect of research and become the forefront of future development.
