Mobility test tracks vision changes in inherited retinal dystrophies
A novel multi-luminance mobility test accurately distinguished normal-sighted subjects from visually impaired subjects with inherited retinal dystrophies and tracked vision declines over time. Researchers enrolled 62 subjects in the prospective, observational study. Normal-sighted and visually impaired subjects completed a multi-luminance mobility test three times over the course of 1 year. Subjects used individual eyes and both eyes during the test, while researchers evaluated accuracy and speed compared with visual acuity and field. Subjects followed arrows on the mobility course and avoided obstacles in or adjacent to their paths. The subjects (Read more...)
