Given the enormous recent interest in functional capabilities related to vision, the goal of this study was to examine the relationship of standard clinical measures of vision (e.g. Snellen acuity) to functioning and well-being. The association between Snellen visual acuity, Amsler grid distortion and presence of diabetic retinopathy with self-reported functioning and well-being (SF-36) were examined in a sample of 327 diabetics from the Medical Outcomes Study (MOS). There was little or no correlation between Snellen visual acuity, Amsler grid distortion or diabetic retinopathy and functioning and well-being (i.e. SF-36 scales). Maximum product-moment correlation was 0.15 with worst eye visual acuity, 0.13 with best eye visual acuity, 0.08 with presence of retinopathy, and 0.10 with Amsler grid distortion. Analysis of variance revealed that visual acuity (both best and worst eye) was statistically related only to the physical function scale; no other exam measure was related to any other SF-36 scale score. Snellen visual acuity, Amsler distortion and diabetic retinopathy correlate weakly with patient self-reported functioning and well-being. Thus, the information provided by functioning and well-being measures is complementary to that of standard clinical measures of visual ability.
鉴于近期人们对与视力相关的功能能力产生了极大兴趣，本研究的目的是探讨视力的标准临床测量指标（如斯内伦视力）与功能及幸福感之间的关系。在医学成果研究（MOS）的327名糖尿病患者样本中，研究了斯内伦视力、阿姆斯勒方格变形以及糖尿病视网膜病变的存在与自我报告的功能及幸福感（SF-36）之间的关联。斯内伦视力、阿姆斯勒方格变形或糖尿病视网膜病变与功能及幸福感（即SF-36量表）之间几乎没有或不存在相关性。最大积矩相关系数分别为：最差眼视力为0.15，最佳眼视力为0.13，视网膜病变存在情况为0.08，阿姆斯勒方格变形为0.10。方差分析显示，视力（最佳眼和最差眼）仅在统计学上与身体功能量表相关；其他检查指标与任何其他SF-36量表得分均无关联。斯内伦视力、阿姆斯勒变形和糖尿病视网膜病变与患者自我报告的功能及幸福感之间的相关性较弱。因此，功能及幸福感测量所提供的信息与视觉能力的标准临床测量信息具有互补性。
