In addition to their restricted peripheral fields, persons with retinitis pigmentosa (RP) report significant problems seeing in low levels of illumination, which causes difficulty with night travel. Several devices have been developed to support the visual needs of persons who have night blindness. These devices include wide-angle flashlights, adapted military light-intensifier devices, and systems that use high-sensitivity (or infrared-sensitive) video cameras. New devices are also in development, including the Minified Augmented-View device, which incorporates expansion of the visual field, along with the enhancement of night vision, to address both the field and night vision needs of persons with RP. The study described in this paper was conducted to provide information about any difficulties in assessing outdoor night mobility in a real-world environment. The results are reported to open an avenue for discussion among professionals in the field. (Includes 3 tables.)
