Retinal nerve fiber layer defects and chronic kidney disease:the Kailuan Eye Study

AIM:To investigate whether retinal nerve fiber layer defects(RNFLDs)is a potential risk factor for chronic kidney disease(CKD)in Chinese adults.METHODS:The Kailuan Eye Study was a populationbased study that included 14440 participants.All participants underwent detailed assessments,RNFLDs were diagnosed using color fundus photographs.RESULTS:Overall,12507 participants[8533 males(68.23%)]had complete systemic examination data and at least one evaluable fundus photograph.RNFLDs were found in 621 participants[5.0%;95%confidence interval(CI):4.6%-5.34%],and 70 cases of multiple RNFLDs were found(11.27%).After adjusting multiple factors,RNFLDs was significantly associated with CKD severity,the ORs of CKD stage 3,stage 4 and stage 5 were 1.698,4.167,and 9.512,respectively.Multiple RNFLDs were also associated with CKD severity after adjusting multiple factors,the ORs of CKD stage 3 and stage 5 were 4.465 and 11.833 respectively.Furthermore,2294 participants had CKD(18.34%,95%CI:17.68%-18.99%).After adjusting for other factors,CKD presence was significantly correlated with the presence of RNFLDs.CONCLUSION:The strongest risk factors for RNFLDs are CKD and hypertension.Conversely,RNFLDs can be an ocular feature in patients with CKD.Fundoscopy can help detect systemic diseases,and assessment for RNFLDs should be considered in CKD patients.

葡萄膜黑色素瘤和视网膜组织相关性的病理学分析（英文）

目的:分析葡萄膜黑色素瘤的形状对视网膜结构的影响。方法:回顾性分析葡萄膜黑色素瘤患者的病理切片和临床资料,分析肿瘤形状、大小、高度-基底比值、视网膜薄变和浸润的差异。结果:本研究包括102例患者(102眼),平均年龄45.6±12.4岁。其中葡萄膜黑色素瘤76眼(75%)为梭形细胞型,6眼(6%)为上皮样细胞型,16眼(16%)为混合细胞型,其它4眼(4%)。按肿瘤部位分:睫状体黑色素瘤3眼(2.9%),睫状体和脉络膜黑色素瘤28眼(27.5%),脉络膜黑色素瘤71眼(69.6%)。视网膜组织的分析中,43眼(43%)发现视网膜变薄,86眼(84%)发现视网膜浸润。肿瘤的高度在1.2~15.6(平均8.3±3.6) mm,肿瘤基底直径为4.8~31.2(平均17.3±6.5) mm。肿瘤峰高度-基底R值为0.53±0.32。视网膜薄变组(n=43)的平均R值显着高于无视网膜薄变组(n=59)(0.69±0.31与0.42±0.27;P<0.01)。视网膜肿瘤浸润组(n=86)的平均R值比无视网膜浸润组(n=16)略高(0.56±0.33比0.41±0.25;P=0.09),但无统计学意义。结论:高R值的肿瘤与其邻近视网膜薄变有关,与视网膜内肿瘤细胞浸润相关性不大。葡萄膜黑色素瘤的切面形状和邻近视网膜组织的受累情况关系紧密。
