目的:研究 DDLS(disk damage likelihood scale)视乳头损伤分期法与开角型青光眼视野损害的相关性,探讨开角型青光眼的早期诊断方法.方法:利用Discam早期青光眼诊断仪彩色视乳头立体成像系统在Screen Vu立体观察镜下确定31例(58眼)开角型青光眼及29例(58眼)可疑青光眼患者视乳头的DDLS分期.所选患者均为中等大小视乳头(2.0～3.0mm).利用 Humphrey 自动电脑视野分析仪30-2程序对上述患者进行视野检测,研究DDLS分期与视野指数平均缺损(MD,mean defect)、视野模式标准差(PSD,pattern standard deviation)及视野损害分期(HPASS,Hodapp-Parrish-Anderson staging system)的相关性.结果:对116眼中等大小视乳头(2.0～3.0mm)开角型青光眼及可疑青光眼患者研究发现,青光眼组DDLS分期与MD(Pearson,r=-0.664,P＜0.000)、PSD(Pearson.r=0.554.P＜0.000)及HPASS(Spearman,r=0.603,P＜0.000)有相关性,相关系数具有统计学意义.可疑青光眼组DDLS分期与MD、PSD及HPASS分期无明显相关性.结论:DDLS视乳头损伤分期法与开角型青光眼视野损害的程度相关,DDLS视乳头损伤分期法有助于开角型青光眼的早期诊断.

AIM:To determine the correlation between the disc damage likelihood scale and visuaI field damage in patients with open angle glaucoma(OAG),and study the method of early diagnosis of OAG.METHODS:Optic nerves of OAG (31 cases,58 eyes)and suspected glaucoma patients (29 cases,58 eyes)were photographed using a digital stereoscopic camera system(Discam,Marcher,Ltd,U.K).Disc damage likelihood scale(DDLS) stages in a screen Vu stereoscope.A system of the Humphrey Field Analyzer (program 30-2,USA)was used to obtain the mean deviation(MD)and pattern standard deviation(PSD)values.The correlations between DDLS and the visual field parameters was evaluated.Findings were assessed by the Pearson correlation coeffidents.RESULTS:116 eyes are with moderate optic nerves(2-3mm).In 58 eyes with open angle glaucoma.the DDLS was significantly correlated with MD (Pearson,r=-0.664,p＜0.01)and PSD(Pearson,r=0.554,P＜O.01).There was no significant correlation of these parameters in suspectious glaucoma patients.CONCLUSION:DDLS iS significantly correlated with the degree of glaucomatous visual field damage in patients with open angle glaucoma,and thus it is helpful in early diagnosis of open angle glaucoma.
