简介:青光眼房水引流装置植入术是目前临床上广为推崇的一种治疗难治性青光眼的有效方法.各引流装置在设计、材料、引流盘的面积和形状及有无阀门或限流器上存在差异.现就临床常用的青光眼房水引流装置的结构特点、作用机制、并发症、不足之处以及当前研究进展做一简要概述.
简介:目的:通过测定糖尿病性白内障患者血清中糖代谢指标、胰岛素抵抗与房水和血清中炎症因子的水平,探讨其相关性。方法:随机选取我院2017-02/2018-01糖尿病性白内障患者69例(观察组)和白内障患者65例(对照组),检测两组患者血清中糖化血红蛋白(HbA1c)、空腹血糖(FPG)、空腹胰岛素(FINS)的水平,计算胰岛素抵抗指数(HOMA-IR);同时检测房水和血清中的胰岛素样生长因子-1(IGF-1)、白细胞介素-6(IL-6)含量,对HbA1c、HOMA-IR与房水和血清中IGF-1、IL-6含量进行相关性分析。结果:对照组血清中的FPG、HbA1c、HOMA-IR,以及房水和血清中IGF-1、IL-6含量显著低于观察组,差异有统计学意义(均P<0.05)。HbA1c与房水及血清中的IGF-1和IL-6均呈正相关(P<0.05)。HOMA-IR与房水及血清中的IGF-1和IL-6均呈正相关(P<0.05)。结论:糖尿病性白内障患者HbA1c、HOMA-IR与房水及血清中的IGF-1、IL-6含量具有相关性,通过对上述指标的测定可以辅助判断病情。
