Abstract Purpose:: Retinotopic mapping in functional Magnetic Resonance Imaging (fMRI) has recently been applied to patients with different forms of partial blindness, albeit with contradicting results. We wanted to investigate how different patterns of visual field loss as induced by age-related macular degeneration (ARMD) or retinitis pigmentosa (RP) influence the topography of brain activation. Methods:: We performed retinotopic mapping in patients with age-related macular degeneration (ARMD, n=5) and retinitis pigmentosa (RP, n=6). FMRI data (T2*-weighted images) were acquired with a 3T Philips Intera MR Scanner. Retinotopic mapping stimulation consisted of a clockwise rotating wedge and an expanding annulus (5 cycles, 32s per cycle, 8Hz flicker, black-and white checkerboard). Data were analyzed with Brain Voyager software (General Linear Model and linear correlation maps). Statistical activation maps were projected onto an anatomical T1-weighted image of the brain and compared to results from 10 healthy subjects.
