The ability of the person with low vision to achieve successful orientation and mobility depends on residual vision, age of onset of visual impairment, posture and balance, intelligence, body image, auditory-tactile abilities, and personality. This study assesses the role of the residual vision and looks in particular at visual fields, spatial contrast sensitivity, and visual acuity. Correlation coefficients indicate that, for low vision patients, spatial contrast sensitivity and visual fields each have more influence on orientation-mobility than does visual acuity.
视力低下者实现成功定向和移动的能力取决于残余视力、视力障碍的发病年龄、姿势和平衡、智力、身体形象、听觉触觉能力以及性格。本研究评估了残余视力的作用，并特别关注视野、空间对比敏感度和视力。相关系数表明，对于低视力患者，空间对比敏感度和视野对定向移动的影响均大于视力。
