Objective: To prove potential difference between black/white and yellow/blue stimulation when using functional magnetic resonance imaging (fMRI) examination in advanced stages of glaucoma disease.
Methods and materials: The authors examined eight patients with various stages of high-tension 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 SPM8 software and GLM. The difference in the n.. Read More»
