目的视力康复的非裔美国人与中央视力障碍（VISRAC）的研究是一个示范项目，评估如何修改视力康复可以提高使用功能vision.Methods五十五个非洲裔美国人40岁及以上的中央视力障碍随机分配到接受无论是诊所为基础的（CB）或家庭为基础的（HB）低视力康复服务。48例受试者完成了研究。主要结果是日常生活活动中功能性视力的变化，采用退伍军人管理局低视力视觉功能问卷（VFQ-48）进行评估。这包括总体视觉能力和视觉能力领域（阅读、移动性、视觉信息处理和视觉运动技能）的评分。通过Rasch分析将每个评分标准化为logit估计值。采用线性回归模型比较两个干预组的总分和各领域得分的差异。结果CB组和HB组在末次访视时的总体视力较基线均有显著改善。CB组显示出比HB组更大的改善（平均值为1.28 vs. 0.87 logits变化），尽管组间差异不显著（p = 0.057）。CB组视觉运动技能评分显示出比HB组评分显著改善（平均值为3.30与1.34 logits变化，p = 0.044）。两组之间阅读和视觉信息处理评分的改善差异不显著（p = 0.054和p = 0.509）。两组都没有显着改善的流动性评分，这是不是康复programmes.Conclusions视力康复是有效的，这项研究的人口，无论位置。CB组表现优于HB组的可能原因包括许多心理社会因素以及诊所环境中更标准化的无干扰工作环境。
Purpose The Vision Rehabilitation for African Americans with Central Vision Impairment (VISRAC) study is a demonstration project evaluating how modifications in vision rehabilitation can improve the use of functional vision.Methods Fifty-five African Americans 40 years of age and older with central vision impairment were randomly assigned to receive either clinic-based (CB) or home-based (HB) low vision rehabilitation services. Forty-eight subjects completed the study. The primary outcome was the change in functional vision in activities of daily living, as assessed with the Veteran's Administration Low-Vision Visual Function Questionnaire (VFQ-48). This included scores for overall visual ability and visual ability domains (reading, mobility, visual information processing, and visual motor skills). Each score was normalized into logit estimates by Rasch analysis. Linear regression models were used to compare the difference in the total score and each domain score between the two intervention groups. The significance level for each comparison was set at 0.05.Results Both CB and HB groups showed significant improvement in overall visual ability at the final visit compared with baseline. The CB group showed greater improvement than the HB group (mean of 1.28 vs. 0.87 logits change), though the group difference is not significant (p = 0.057). The CB group visual motor skills score showed significant improvement over the HB group score (mean of 3.30 vs. 1.34 logits change, p = 0.044). The differences in improvement of the reading and visual information processing scores were not significant (p = 0.054 and p = 0.509) between groups. Neither group had significant improvement in the mobility score, which was not part of the rehabilitation program.Conclusions Vision rehabilitation is effective for this study population regardless of location. Possible reasons why the CB group performed better than the HB group include a number of psychosocial factors as well as the more standardized distraction-free work environment within the clinic setting.
