Motion Perception in Central Field Loss: Visual Field Contributions



Purpose: Individuals with central field loss (CFL) have impaired acuity, contrast sensitivity and stereopsis. However, their ability to judge heading direction does not appear to be impaired in the absence of noise (Odom et al. ARVO 2010). Consistent with this finding, our recent study shows that speed and direction discrimination in this group are comparable to age-matched controls (Shanidze & Verghese OSAFV 2018). Here, we aim to investigate whether motion perception depends on the location, extent and eccentricity of the missing information.

Methods: Observers performed a 2AFC task on
