  Objective: The aim was to find, whether the activations in fMRI induced by black-white and yellow-blue stimulation in patients with normotensive glaucoma will be similar to those in patients with hypertensive glaucoma. Methods and subjects: The authors examined eight patients with various stages of normotensive glaucoma using functional magnetic resonance imaging (fMRI). The group was compared to a group of eight healthy persons. Measurements were performed on the Philips Achieva 3T TX MR system using the BOLD method. Optical stimulation was provided by black-white and yellow-blue checkered patterns alternated with their negatives with a frequency of 2 Hz. Each measurement consisted of a sequence with five 30-second periods of active phase and five resting periods of the same length. The obtained data were processed by SPM 8 software and genera..
