Relative Eye Position During Monocular and Binocular Pursuit in Central Field Loss



Smooth pursuit eye movements are used to stabilize a moving stimulus on the retina. In the case of a spot stimulus the fovea closely tracks the moving target. As such, eye movements are likely conjugate during binocular tracking in the fronto-parallel plane, with the foveas of both eyes following the object of interest. Here, we investigate whether this conjugate nature is maintained in patients with central field loss (CFL), who commonly use eccentric, often non-corresponding, retinal locations during monocular viewing. Kabanarou et al. (2006) showed changes in gaze position, in CFL patients
