研究目的:

本研究通过对CKD患者黄斑区的微血管改变分析为横断面观察分析,尝试采用OCTA量化不同程度CKD患者黄斑区的微循环状态,预研究表明非圆指数可以作为CKD进展中监测FAZ改变的指标;CKD患者中黄斑区血流密度改变与CKD严重程度密切相关;深层视网膜旁中心四血流密度下降出现在CKD临床前期,可作为早期筛查CKD的潜在指标,需要进一步纵向深入研究。另外,通过OCTA技术发现,CKD患者中视盘周围毛细血管血流密度与病情严重程度密切相关,本研究尝试通过病例调查,筛分出典型CKD患者眼底黄斑区微血管异常、眼底视盘周围微循环异常和脉络膜厚度变化的样本库,为分析、监测CKD患者眼底视网膜神经改变的潜在指标,为进一步理解CKD患者眼底微血管及神经病变之间的关系提供新的方向。  

Objectives of Study:

In this study, the microvascular changes in the macular area of CKD patients were analyzed as a cross-sectional observation and analysis, and OCTA was used to quantify the microcirculation state of the macular area in patients with CKD of different degrees. The change of blood flow density in the macular area of CKD patients is closely related to the severity of CKD; the decrease of blood flow density in the deep pararetinal center four appears in the preclinical stage of CKD, which can be used as a potential indicator for early screening of CKD, and further longitudinal and in-depth research is needed. In addition, through OCTA technology, it was found that the blood flow density of capillaries around the optic disc in CKD patients is closely related to the severity of the disease. This study tried to screen out the microvascular abnormalities in the macular area of the fundus of the typical CKD patients, abnormalities of the microcirculation around the optic disc in the fundus and the optic disc through case investigation. The sample library of changes in choroidal thickness provides a new direction for analyzing and monitoring the potential indicators of retinal nerve changes in the fundus of CKD patients, and for further understanding the relationship between fundus microvessels and neuropathy in CKD patients.

药物成份或治疗方案详述:

本研究收集同济大学附属同济医院眼肾科确诊为CRF的CRF患者200例(400眼)和健康对照者50例(100眼)。根据CKD分类,将入组受试者(n=200)分为4组:CDK1-2(A组=50)、CKD3(B组=50)、CKD4(C组=50)和CKD5(D组 = 50) 和 健康对照(E组=50)。比较各组视网膜病变进展与肾病并发进展关系的队列研究观察时间为0.5Y、1Y、1.5Y、2Y、2.5Y、3Y,观察各项指标,包括:视网膜病变指标如:FAZ面积、周长、非圆形指数、中心凹旁血流密度,以及肾功能进展指标如:肾小球滤过率、血生化、尿检、微量白蛋白尿、CKD指数等,综合评估两者之间的关系。 

Description for medicine or protocol of treatment in detail:

This study collected 200 CRF patients (400 eyes) from the Department of Ophthalmology and Nephrology, Tongji Hospital Affiliated to Tongji University and 50 healthy controls (100 eyes) who were diagnosed with CRF. According to the CKD classification, the enrolled subjects (n=200) were divided into 4 groups: CDK1-2 (group A=50), CKD3 (group B=50), CKD4 (group C=50) and CKD5 (group D) )) = 50) and healthy controls (group E = 50). The observation time of the cohort study comparing the progression of retinopathy and the concurrent progression of nephropathy in each group was 0.5Y, 1Y, 1.5Y, 2Y, 2.5Y, 3Y, respectively. Observe various indicators, including: retinopathy indicators such as FAZ area, perimeter, non-circular index, parafoveal blood flow density, renal function progress indicators such as: glomerular filtration rate, blood biochemistry, urinalysis, microalbuminuria , CKD index, etc., comprehensively evaluate the relationship between them.
