Contrast sensitivity function and mobility in elderly patients with macular degeneration.
Eleven control subjects, 64-79 years of age, and 10 subjects with macular degeneration, 70-82 years of age, were included in this study. Each participant was tested for visual acuity, spatial and temporal contrast sensitivity, and mobility in an unfamiliar environment. The course was designed with a pair of steps, ramps, and a level pathway. The subjects were timed and videotaped. The number of errors was recorded. Visual acuity and contrast sensitivity were significantly different between groups. The time to complete the course was significantly different between groups; however, the difference did not remain significant after age-adjustment.
