青光眼论文青光眼结构与功能的相关性分析

1、青光眼论文：青光眼结构与功能的相关性分析【中文摘要】研究青光眼结构和功能的相关性方法：1.用OCT及标准自动视野计测量开角型青光眼患者27人49眼的视盘面积(DA),视杯面积(CA),盘沿面积(RA),视杯容积(CV)盘沿容积(RV),杯盘面积比(CDR),线性杯盘比(LCDR),视盘竖径(DV),视盘横径(DH)及平均视野缺损(MD),研究其相关性。2.用OCT及标准自动视野计测量开角型青光眼患者21人34眼视盘的视网膜神经纤维层厚度及视野。将代表视网膜神经纤维层厚度的盘沿一周分为12(S1-S12)区,将视野分为21区(Z1-Z21),研究其对应关系。结果：1.视盘参数中以杯盘面积比(CD

2、R)、视杯面积(CA)和线性杯盘比(LCDR)与视野缺损的相关性最大。2.青光眼的视野缺损多首先发生于上下方的旁中心区,即出现弓形暗点；盘沿的丢失多发生于上下极。一侧视野的缺损,则对应相对侧的神经纤维的损害。结论：青光眼的结构和功能具有明显的相关性。这一结论对青光眼的临床早期诊断具有重大意义。【英文摘要】To investigate the relationship between structure and function in glaucoma.Methods 1.49 glaucomatous eyes(27 patients) were examined with OCT and S

3、AP.We could get paramters of optic disc,such as DA,CA,RA,CV,RV,CDR,LCDR,DV,DH and parameter of visual field such as MD. To investigate the relationship between of them. 2.34 glaucomatous eyes(21 patients) were examined with OCT and SAP.The total rim was divided into 12 sectors,and the visual field w

4、as divided into 21 zones. To investigate the relationship between the sectors and zones.Results 1. CDR,CA,LCDR had the most close relationship with MD. 2.The early defect of visual field occurred at paracentral field.The damage of rim began with the inferior and superior.The visual field defect alwa

5、ys caused the damage of RNFL in the opposite hemiretina.Conclusion The structure and function have close relationgship in glaucoma.The result is valuable in diagnosis of early glaucoma.【关键词】青光眼 视野 视盘参数 视网膜神经纤维层 相关性【英文关键词】glaucoma visual field parameter of optic disc RNFL relationship【目录】青光眼结构与功能的相关性分析 摘要 2-3 Abstract 3 引言 5-6 第1章 青光眼视盘定量参数与视野缺损的相关性分析 6-10 1.1 资料与方法 6 一般资料 6 1.1.2 仪器与方法 6 1.2 结果 6-8 1.3 讨论 8-10 第2章 青光眼视野缺损与神经纤维层损失的相关性分析 10-16 2.1 资料与方法 10 2.1.1 一般资料 10 2.1.2 仪器与方法 10 2.2
