摘要
目的探讨青光眼患者视乳头不同方位视网膜神经纤维层厚度与对应区域视野缺损之间的相关性.方法对本院40名有过急性发作史的,眼压控制25 mmHg以下2周以上的原发急性闭角型青光眼患者,采用光学相干断层成像技术(OCT)进行6个方位的视神经纤维层(RNFL)厚度检测和全自动视野计进行72点视野检查.比较患者的颞上、颞下及平均视网膜神经纤维层厚度与对应区域鼻下、鼻上及平均视野缺损之间的关系.结果颞下RNFL厚度与鼻上视野缺损具有高度相关性(r=-0.81,P<0.05),颞上RNFL厚度与鼻下视野缺损具有高度相关性(r=-0.83,P<0.05),平均RNFL厚度与平均视野缺损具有负相关(r=-0.62,P<0.05).结论RNFL厚度一定程度上可以反应视野缺损深度.
Objective To investigate the correlation between the thickness of retinal nerve fiber layer(RNFL)and corresponding visual field defect in glaucoma patients.M lethods Forty angle-closure glaucoma patients were enrolled.Optical coherence tomography(OCT)was performed to obtain the thickness of RNFL in 6 positions of optic nerve head and the corresponding visual field sensitivity or visual field defect.Association was analyzed between thickness of temporal superior RNFL and the visual field defect of nasal-inferior,between the thickness of temporal-inferior RNFL and the visual field defect of nasal-superior,between the thickness of mean RNFL and mean field defect.Results Linear correlation was found between the temporal-superior RNFL thickness and the nasal-inferior visual field defect(r=-0.83),between the temporal-inferior RNFL thickness and the nasal-superior visual field defect(r=-0.80).The negative correlation(r=-0.60)was found between the mean thickness of RNFL and the mean visual defect.Conclusion The thiekness of RNFL can partly reflect the depth of the visual field defect.
