PURPOSE We evaluated optic radiation (OR) damage in patients with glaucoma by using fractional anisotropy (FA) of diffusion-tensor magnetic resonance imaging. METHODS We studied 29 patients with glaucoma and 19 healthy controls. Regions of interest were placed over the bilateral anterior and posterior ORs on the FA maps, and the FA value of each region(More)
PURPOSE To evaluate alteration of the optic radiation (OR) in patients with retinitis pigmentosa (RP) using fractional anisotropy (FA) measured by diffusion tensor MRI. METHODS We performed MRI and evaluated alteration of the ORs in 17 patients with RP and 27 healthy controls. Regions of interest were placed over the bilateral anterior and posterior areas(More)
BACKGROUND To demonstrate the efficacy of positron emission tomography (PET) for examining multiple sclerosis (MS) patients with hemianopia. CASE A 20-year-old man visited us with a complaint of left homonymous hemianopia and headache. OBSERVATIONS The patient's visual acuity was 1.2 (n.c.) OD and 0.9 (1.0) OS. Magnetic resonance imaging (MRI) showed a(More)
A 43-year-old woman with drug-related blepharospasm was followed up for 22 months. She had undergone etizolam treatment for 19 years for indefinite complaints. We examined her cerebral glucose metabolism 5 times (between days 149 and 688 since presentation), using positron emission tomography, and identified regions of interest in the thalamus, caudate(More)
BACKGROUND It has recently become clear that glaucoma is not only an ocular disease, but involves central visual pathways as well. The purpose of this study was to examine functional and structural alterations in the brains of glaucoma patients. DESIGN Case-control study in a hospital. PARTICIPANTS A total of 32 glaucoma patients and 19 healthy(More)
