目的：探讨视力损害的临床指标与日常生活能力的关系。方法：120例不同原因的低视力患者参与研究。在双眼条件下，通过测量距离视力、近字视力、墨尔本边缘测试对比灵敏度、Pelli-Robson图对比灵敏度和视野来评估视力障碍。使用墨尔本低视力ADL指数（MLVAI）评估ADL表现，该指数部分是工具性ADL的观察表现评估，部分是基本自我照顾ADL的自我报告评估。结果：所有视力指标与MLVAI总分均有较高的统计学意义相关。近词敏锐度，相关性最强（r(s) = -0.86, p < 0.001），其次是墨尔本边缘测试对比敏感度（r(s) = 0.80, p < 0.001）。视野相关性最弱（r(s) = 0.56, p < 0.001）。年龄、近词敏锐度、墨尔本边缘测试对比敏感度和视野合计占MLVAI总分方差的82.2%（校正R-2， p < 0.001）。观察到的工具性adl的表现评估的所有相关性都高于基本自我保健adl的自我报告评估。结论：临床视力损害测量与MLVAI测量的adl能力高度相关。
Purpose: To determine the relationship between clinical measures of vision impairment and the ability to perform activities of daily living (ADLs).Methods: One hundred and twenty subjects with low vision from a variety of causes participated in the study. Vision impairment was assessed under binocular conditions by measuring distance visual acuity, near word acuity, Melbourne Edge Test contrast sensitivity, Pelli-Robson Chart contrast sensitivity and visual fields. The ADL performance was assessed using the Melbourne Low Vision ADL Index (MLVAI), which is in part an observed performance assessment of instrumental ADLs and in part a self-report assessment of basic self-care ADLs.Results: All vision measures had a high, statistically significant correlation with MLVAI total score. Near word acuity, had the strongest correlation (r(s) = -0.86, p < 0.001), followed by Melbourne Edge Test contrast sensitivity (r(s) = 0.80, p < 0.001). Visual field had the weakest correlation (r(s) = 0.56, p < 0.001). Together, age, near word acuity, Melbourne Edge Test contrast sensitivity and visual field accounted for 82.2% (adjusted R-2, p < 0.001) of the variance in MLVAI total score. All correlations obtained were higher for the observed performance assessment of instrumental ADLs than for the self-report assessment of basic self-care ADLs.Conclusions: Clinical vision impairment measures are highly correlated with capacity to perform ADLs, as measured by the MLVAI.
