Purpose: Low vision is typically characterized by deficits in spatial vision, such as visual acuity and contrast sensitivity. However, motion perception, which is particularly important in dynamic environments such as street crossings or the sports arena, has not been widely assessed in this population. Therefore, we conducted a cross-sectional clinical study to determine if individuals with low vision could complete a global motion task, and to compare their performance to that of normally sighted individuals.

Methods: We assessed global motion perception in 31 individuals with low vision (23.9±6.5 yr; range 13 to 37 yr) and 19 controls (30.0±4.6 yr; range 24 to 37 yr) using random dot kinematograms that were scaled in size to account for visual acuity deficits in the low vision group. Vertical translation and radial global motion coherence thresholds were measured using a dot size of 2.0 logMAR in both groups. A subset …
