To examine three types of visual ability-ambient acuity, standard lighting acuity, and retinal acuity-and their relationship with self-reported disability.
Cross-sectional prevalence survey.
New York, New York.
Community-dwelling older people.
Ambient acuity assessed using a near reading card; standard lighting acuity and retinal acuity assessed using the Retinal Acuity Meter. Difficulty in activities of daily living was assessed according to self-report.
Mean logMAR acuities were 0.44 (20/56) for ambient acuity, 0.33 (20/44) for standard lighting acuity, and 0.19 (20/31) for retinal acuity (all pairwise differences, P < .001). Given the distribution of disability by ambient acuity in this sample, improving ambient acuity to the level of retinal acuity could potentially reduce self-care disability 22%.
Better utilization of retinal acuity through optimal ophthalmologic care and improvement in lighting would likely reduce disability in older adults.
研究三种视觉能力——周边视力、标准照明视力和视网膜视力——及其与自我报告的残疾状况之间的关系。
横断面患病率调查。
纽约州纽约市。
社区居住的老年人。
使用近读卡片评估周边视力；使用视网膜视力计评估标准照明视力和视网膜视力。根据自我报告评估日常生活活动的困难程度。
周边视力的平均对数最小分辨角视力为0.44（20/56），标准照明视力为0.33（20/44），视网膜视力为0.19（20/31）（所有两两比较差异，P <.001）。根据该样本中周边视力的残疾分布情况，将周边视力提高到视网膜视力水平可能会使自我护理残疾率降低22%。
通过优化眼科护理更好地利用视网膜视力并改善照明，可能会降低老年人的残疾率。
