Outline of Final Research Achievements |
We have been conducted longitudinal data aquisition and have analyzed cross-sectional data including mainly anatomical 3D-T1WI images and clinical visual field information, MD(mean deviation). Voxel-based regressing analysis with SPM12(Statistical Parametric Mapping software 12) revealed that gray matter volume of the specific region in primary visual cortex could correspond to the degree of glaucoma-related visual field loss. Patients with glaucoma are often unaware of their visual field loss because that glaucoma-related visual sensitivity loss starts from periphery of visual field. Our results could be of clinical use for picking up asymptomatic glaucoma by detecting specific atrophy via brain MRI medical checkup.
