EDI-OCT在视网膜分支静脉阻塞患者筛板厚度测量中的应用
Application of EDI-OCT in measuring the plate thickness in patients with branch retinal vein occlusion
摘要
Abstract
Objective To analyze the application value of enhanced depth imaging optical coherence tomography (EDI-OCT) in measuring the lamina cribrosa thickness(LCT) in patients with branch retinal vein occlusion (BRVO).Methods The clinical data of 65 patients with unilateral BRVO treated in our hospital from September 2014 to March 2016 were selected as the observation group.The single healthy eyes of 40 healthy individuals who received physical examination in the hospital during the same period were selected as the control group.The changes of retinal nerve fiber layer (RNFL) thickness,LCT,central corneal thickness,axial length,transverse diameter of optic disc,vertical diameter of optic disc,diopter and extent of visual field defect in the two groups were determined by EDI-OCT.Results There was no significant difference in the central corneal thickness,axial length,transverse diameter of optic disc,vertical diameter of optic disc and diopter between the two groups (all P ＞ 0.05).LCT of different regions of optic disc in the observation group were lower than those in the control group (all P ＜ 0.05).The range of visual field defects in the observation group was larger than that in the control group,and the RNFL thickness was lower than that in the control group (P ＜ 0.05).LCT was positively correlated with the thickness of whole RNFL in patients with BRVO,and was negatively correlated with the visual field defects (P ＜ 0.05).Conclusion EDI-OCT is an effective means for measuring LCT.LCT of patients with glaucoma BRVO is thinner than that of normal healthy people,and LCT is positively correlated with RNFL.thickness,and negatively correlated with visual field defects.关键词
