Vision and self-reported mobility performance in patients with low vision.

Background: As vision plays a significant role in mobility performance, it is usual to refer low vision patients, particularly those who complain of mobility difficulties, for orientation and mobility (O&M) training to help them maintain safe independent travel. Our study aimed to determine whether there was a relationship between measures of vision and self-reported mobility, and the applicability of a patient-based mobility assessment in patients with heterogeneous causes of visual loss.

Method: We assessed the high and low contrast visual acuity, visual field and scanning ability of 30 patients with low vision.
