Abstract

The presence of a general global motion processing deficit in amblyopia is now well established, although its severity may depend on image speed and amblyopia type, but its underlying cause(s) is still largely indeterminate. To address this issue and to characterize further the nature of the global motion perception deficit in human amblyopia, the effects of varying spatial offset (jump size—¿s) and temporal offset (delay between positional updates—¿t) in discriminating global motion for a range of speeds (1.5, 3 and 9 °/s) in both amblyopic and normal vision were evaluated.
