To access the non-Gaussion water diffusion characteristic of normal tension glaucoma (NTG), we analyzed the diffusion parameters generated from diffusion kurtosis imaging (DKI). The parameters derived from DKI within changed brain regions of NTG group were reduced and involved the occipital lobe. The visual cortex in NTG group had lower degree of diffusional heterogeneity and microstructural complexity compared to normal control (NC) group.
