本研究评估了视网膜色素变性（RP）对正常和降低照明条件下的移动性能（步行速度，移动事件）和自我感知的移动困难的影响。结果表明，RP科目旅行更慢，比正常视力的科目，正常视力和RP科目旅行更慢，减少照明，RP科目是5倍，更有可能有一个流动性事件减少照明比正常视力的科目。步行速度与视觉特征显著相关：对数最小分辨角（log MAR），对数峰值对比敏感度（log CS）和视野范围。RP受试者步行速度的近70%的方差由log CS和视野范围解释。对移动问卷的答复显示，80%的RP受试者经历了移动困难。此外，自我报告的与移动相关的行为与步行速度有统计学相关性。
This study evaluated the effects of retinitis pigmentosa (RP) on mobility performance (walking speed, mobility incidents) under conditions of normal and reduced illumination and on self-perceived mobility difficulties. The results showed that RP subjects travel more slowly than the normally sighted subjects, that both normally sighted and RP subjects travel more slowly under reduced illumination, and that RP subjects are five times more likely to have a mobility incident under reduced illumination than the normally sighted subjects. Walking speed was significantly correlated with the visual characteristics: log minimum angle of resolution (log MAR), log peak contrast sensitivity (log CS), and visual field extent. Nearly 70% of the Variance in the RP subjects' walking speed was accounted for by log CS and visual field extent. Responses on a mobility questionnaire showed that 80% of the RP subjects experienced mobility difficulty. Furthermore, self-reported, mobility-related behaviors were statistically related to walking speed.
