Motion Perception in Central Field Loss



Healthy peripheral retina is exquisitely sensitive to fast speeds. Individuals with central field loss (CFL) typically only have residual peripheral vision and studies suggest they become adept at using peripheral motion information, as in the case of vection (Tarita-Nistor et al. 2008). However, we showed that smooth pursuit in CFL is impaired across a range of speeds and visual acuity cannot explain this decrement in performance (Shanidze et al. 2016). Thus, the question remains whether this deficiency is due to oculomotor limitations, or a potential impairment of peripheral motion
