作为病例对照研究的一部分，奥克兰髋部骨折研究（1991-1994），作者研究了视力受损与髋部骨折风险之间的关系。研究对象（911例和910例60岁及以上的对照组）完成了一份调查问卷，并进行了视力测量，包括视力和立体视觉（深度感知）的测量。在调整年龄、性别、代理反应、每周活动小时数和身高后，双眼视力低于20/60与髋部骨折风险增加有统计学显著相关(优势比(OR) = 1.5；95%可信区间（CI）： 1.1, 2.0)，双眼视力差（小于20/100）（OR = 2.4; 95% CI: 1.0, 6.1）。没有深度感知是；与风险增加相关（OR = 6.0 95% CI: 3.2, 11.1），以及立体视功能下降（趋势p = 0.0001），自我报告视力不良（OR = 1.4; 95% CI: 1.0, 1.9），摔倒时未戴眼镜（OR = 1.2; 95% CI: 1.0, 1.6），以及自上次眼科检查后时间增加（趋势p = 0.03）。由于视力或立体视觉不良导致髋部骨折的人群归因风险为40%。视觉因素是影响髋部骨折危险的重要跌倒相关因素。髋部骨折的风险可通过矫正屈光不正、改善立体视觉和定期进行眼科检查来降低。
As part of a case-control study, the Auckland Hip Fracture Study (1991-1994), the authors examined associations between impaired vision and risk of hip fracture. Subjects (911 cases and 910 controls aged 60 years or older) completed a questionnaire and had vision measurements taken, including measurements of visual acuity and stereopsis (depth perception). Binocular visual acuity worse than 20/60 was statistically significantly associated with increased risk of hip fracture after adjustment for age, sex, proxy response, hours of activity per week, and height (odds ratio (OR) = 1.5; 95% confidence interval (CI): 1.1, 2.0), as was having poor vision (less than 20/100) in both eyes (OR = 2.4; 95% CI: 1.0, 6.1). Having no depth perception was ;associated with increased risk (OR = 6.0 95% CI: 3.2, 11.1), as were categories of decreasing stereopsis (trend p = 0.0001), self-reported poor vision (OR = 1.4; 95% CI: 1.0, 1.9), not wearing glasses at the time of the fall (OR = 1.2; 95% CI: 1.0, 1.6), and increasing time since the last eye examination (trend p = 0.03). The population attributable risk of hip fracture due to poor visual acuity or stereopsis was 40%. Visual factors are important fall-related factors which influence risk of hip fracture. Risk of hip fracture may be decreased by correcting refractive error, improving stereopsis, and administering regular eye examinations.
