Abstract

Retinitis pigmentosa patients experience severe limitations in their ability to adapt to changing light levels. Not only is their adaptation rate slower than that in persons with normal vision (impairing them in indoor-outdoor transitions), but the dynamic range over which they can function comfortably appears to be limited. These symptoms appear to become more serious as the disease progresses, but the clinical impression gained from patients suggests that this factor is only of minor importance.
