Mapping the binocular scotoma in macular degeneration



Macular degeneration (MD) affects the central portion of the retina around the fovea, resulting in a scotoma. When the binocular scotoma obscures an object of interest, individuals with MD miss information and are often unaware of it, which creates difficulties in the performance of daily-living tasks. We propose a method to map precisely the binocular scotoma. 


Seven individuals with MD (mean age = 75; four with binocular scotomas) and 4 age-matched controls (mean age = 68) participated in our study. We measured the peripheral fixation locus, the location of the foveal pit and the extent of
