Резюме
Diabetic retinopathy (DR) is the leading cause of impaired visual function and blindness in adults. The fundus photographs were examined to detect DR. The DR severity was graded non-proliferative diabetic retinopathy (NPDR) and proliferative diabetic retinopathy (PDR) according to the International Clinical Diabetic Retinopathy and Diabetic Macular Edema Disease Severity Scales. The pathogenesis of DR is complex and not fully understood, and platelet aggregation, microvascular damage, microvascular enlargement, leakage, hemorrhage, or obstruction, resulting in retinal hypoxia and retinal neovascularization. Traditional Chinese medicine (TCM) diagnostic tools are non-invasive and convenient. This study apply TCM diagnostic tools for clinical diseases, providing objective diagnostic data for evaluation to assess the association of blood stasis and DR. Furtherly we would evaluate the sensitivity and specificity of TCM diagnostic tools.
This study is a prospective cross-sectional study. We enroll participants form the department of Chinese medicine, China Medical University Hospital. In total, 100 participants , composed of 50 of type 2 diabetes and 50 of diabetic retinopathy, whom previously had a retinal examination. We apply tongue diagnosis system, pulse wave analysis, body constitution questionnaires, and nailfold capillaroscopy to assess the differences of TCM diagnosis in DR.
This study aims to identify the clinical symptoms of DR with TCM diagnostic tools and investigate the pattern difference and treatment for DR. Furtherly, we could design a clinical trial with improving blood circulation to treat or prevent DR, and improve the health status and quality of life in patients with type 2 diabetes.

Резултат
Първични изходни мерки
1. Automatic tongue diagnosis [12 months]
We observe the tongue features of blood stasis, such as bluish tongue, petechiae, and engorged sublingual vessels, and compare the relationship between diabetic retinopathy and blood stasis.
2. body constitution questionnaire [12 months]
We observe the body constitution questionnaires, such as yi deficiency, yang deficiency and phlegm-stasis, and compare the relationship between diabetic retinopathy and blood stasis.
3. Nailfold videocapillaroscopy (NVC) [12 months]
We evaluate the capillary density, length, morphology, distribution, presence of enlarged loops or hemorrhages, and blood flow. NVC score was used to quantitate the aforementioned characteristics.
4. pulse examinatin [12 months]
