We investigated the mobility performance of subjects with retinitis pigmentosa (RP) as a function of clinical measures of residual vision and psychological variables. We found a highly significant correlation between clinical measures of residual vision and mobility. Pelli-Robson contrast sensitivity and residual visual field together explained 64% of the variance in mobility performance in an indoor shopping mall. We suggest a simple new clinical method of scoring the visual field for predicting mobility performance, the RP Concentric Field Rating. The RP Concentric Field Rating alone explained 60% of the variance in mobility performance. In spite of expectations derived from reading the recent literature, we did not find a significant correlation between psychological variables and mobility performance in a group of subjects with RP.
我们研究了视网膜色素变性（RP）患者的移动能力表现与残余视力的临床指标及心理变量之间的关系。我们发现残余视力的临床指标与移动能力之间存在高度显著的相关性。在室内购物中心，佩利-罗布森对比敏感度和残余视野共同解释了移动能力表现中64%的方差。我们提出了一种简单的新临床方法来对视野进行评分以预测移动能力表现，即RP同心视野评分。仅RP同心视野评分就解释了移动能力表现中60%的方差。尽管从阅读近期文献中得出了预期结果，但我们在一组RP患者中并未发现心理变量与移动能力表现之间存在显著相关性。
