Gaze Changes from Binocular to Monocular Viewing during Smooth Pursuit in Macular Degeneration



Purpose: The asymmetrical nature of bilateral central field loss in macular degeneration (MD) makes viewing strategies difficult to predict. Previous work examined gaze shifts from monocular to binocular fixation and found that the position change was negligible for the better eye, but significant for the worse eye (Kabanarou et al. 2006). Here, we set out to determine if analogous gaze shifts occurred when switching from monocular to binocular smooth pursuit. Methods: Participants (6 MD, 2 age-matched controls) were asked to pursue a 1° circular target in a step ramp paradigm (Rashbass 1961)
