摘要
目的探讨糖尿病脉络膜病变的发展与糖尿病患者脉络膜背向散射积分（integratedbackscatter，IBS）之间的关系。方法糖尿病患者80例（158只眼），按糖尿病视网膜病变（diabeticretinopathy，DR）程度分为3组：糖尿病不伴DR组、单纯型DR组和增殖型DR组，正常对照组80例（160只眼），应用HPSonos5500超声诊断仪，分别测量受检者鼻侧、中部及颡侧的脉络膜IBS值，并计算校正IBS值（IBS％）。结果随着DR病变程度的加重，脉络膜IBS值（糖尿病不伴DR组31．21dB，单纯型DR组32．47dB，增殖型DR组33．86dB）和IBS％增加，各组间差异有统计学意义（P《0．01）。结论糖尿病患者脉络膜的IBS和IBS％随着病情的发展而增高，IBS技术是评价糖尿病脉络膜病变的有效方法。
Objective Objective To investigate the relationship between choroidopathy and integrated backscatter（IBS） of choroid in diabetes mellitus（DM） patients. Methods Eighty DM patients of 158 eyes were divided into 3 groups by the course of diabetic retinopathy（DR）--DM patients without DR group,DM patients with the background DR, DM patients with the proliferative DR. 80 normal persons of 160 eyes were the control group. Their IBS values were measured on nose side, temple side and middle side of choroid by HP Sonos 5500,and the correction IBS values（IBS%） were calculated. Results With the deterioration of DR,the IBS and IBS% of choroid increased. The statistical significance difference were found in various groups（ P〈 0.01）. Conclusions With the deterioration of diabetic choroidopathy, the IBS and IBS% increased. The IBS technique is useful method to assess the diabetic choroidopathy.
