摘要:
目的　使用磁共振扩散张量成像技术（ｄｉｆｆｕｓｉｏｎｔｅｎｓｏｒｉｍａｇｉｎｇ，ＤＴＩ）研究正常眼压性青光眼（ｎｏｒｍａｌｔｅｎｓｉｏｎｇｌａｕｃｏｍａ，ＮＴＧ）患者视路的改变，探讨其与ＮＴＧ临床分期的相关性。方法　对３０例（６０眼）ＮＴＧ患者（ＮＴＧ组）和３０例（６０眼）健康志愿者（对照组）进行了前瞻性研究。ＮＴＧ临床分期使用Ｈｏｄａｐｐ-Ａｎｄｅｒｓｏｎ-ｐａｒｒｉｓｈ（ＨＡＰ）系统进行分类。所有受试者均进行磁共振ＤＴＩ扫描检测，利用软件处理定量获取视神经、视交叉、视束的各向异性分数（ｆｒａｃｔｉｏｎａｌａｎｉｓｏｔｒｏｐｙ，ＦＡ）、平均扩散系数（ａｖｅｒａｇｅｄｉｆｆｕｓｉｏｎｃｏｅｆｆｉｃｉｅｎｔ，ＡＤＣ），对比分析ＮＴＧ组与对照组视路改变区域，并检验ＮＴＧ组视路改变程度与临床分期的相关性。结果　与对照组相比，ＮＴＧ组视神经、视交叉及视束的ＦＡ值均明显降低，ＡＤＣ值均明显升高（均为Ｐ＜０．００１）；ＮＴＧ组两侧视神经、视交叉、视束的平均ＦＡ值和ＡＤＣ值均与ＮＴＧ临床分期具有相关性，其中视神经的ＦＡ值与ＮＴＧ临床分期相关性最强（ｒ＝０．７５２，Ｐ＜０．００１），而视束的ＡＤＣ值与ＮＴＧ临床分期相关性最弱（ｒ＝－０．３３１，Ｐ＜０．００１）。结论　ＤＴＩ有望成为临床诊断ＮＴＧ的可能补充手段。
Abstract:
Objective To study the changes of optic pathway in normal tension glaucoma ( NTG) by using diffusion tensor imaging ( DTI) ,and discuss the correlation between the DTI-derived parameters and NTG clinical stages. Methods Thirty cases of NTG patients and 30 cases of healthy control volunteers were prospectively studied. NTG clinical stages were classified by using HodappAnderson-parrish ( HAP) system. All subjects underwent 3. OT MRI-DTI scan test to obtain the fractional anisotropy ( FA) value and average diffusion coefficient ( ADC) value of the optic nerve,optic chiasm and optic tract by using quantitative software process. The visual pathway change region between NTG group and control group was compared,and the correlation between the changes of visual pathway and degree of clinical staging in the NTG group was tested. Results Compared with the control group,FA values of optic nerve,optic chiasm and optic tract in the NTG group showed the significant decrease,while the ADC values were significantly increased ( all P < 0. 001) ; FA and ADC values of the bilateral optic nerve,optic chiasm and optic tract in the NTG group were correlated with NTG clinical stages. FA value of optic nerve in the NTG group had the strongest correlation with NTG clinical stages ( r = 0. 752,P < 0. 001) ,while ADC value of optic tract in the NTG group had the weakest correlation with NTG clinical stages (r = - 0. 331,P < 0. 001). Conclusion DTI can be used as a potential norunvasive manner for clinically diagnosing NTG.
