A vision screening program was established at a regional center for individuals with severe or profound mental retardation. The visual acuity measure used was the acuity card procedure, a type of forced-choice preferential looking. Acuity values were evaluated in terms of test-retest reliability as well as inter- and intraobserver reliability. Acuity results compared favorably to those obtained in less compromised populations, and we conclude that the acuity card procedure is a useful screening tool for this population. Suggestions for its application in evaluating functional vision were also discussed.
在一个地区中心为重度或极重度智力障碍者设立了视力筛查项目。所使用的视力测量方法是视力卡程序，这是一种强制选择优先注视法。从重测信度以及观察者间和观察者内信度方面对视力值进行了评估。视力结果与在情况较好人群中获得的结果相比很有利，并且我们得出结论，视力卡程序是针对该人群的一种有用的筛查工具。还讨论了其在评估功能性视力方面应用的建议。
