Visual impairment is a large and growing socioeconomic problem. Good evidence on rehabilitation outcomes is required to guide service development and improve the lives of people with sight loss. Of the 478 potentially relevant articles identified, only 58 studies met our liberal inclusion criteria, and of these only 7 were randomized controlled trials. Although the literature is sufficient to confirm that rehabilitation services result in improved clinical and functional ability outcomes, the effects on mood, vision-related quality of life (QoL) and health-related QoL are less clear. There are some good data on the performance of particular types of intervention, but almost no useful data about outcomes in children, those of working age, and other groups. There were no reports on cost effectiveness. Overall, the number of well-designed and adequately reported studies is pitifully small; visual rehabilitation research needs higher quality research. We highlight study design and reporting considerations and suggest a future research agenda.
视力障碍是一个庞大且日益严重的社会经济问题。为了指导服务的发展和改善视力障碍患者的生活，需要有良好的康复效果证据。在确定的 478 篇潜在相关文章中，只有 58 项研究符合我们的广泛纳入标准，其中只有 7 项是随机对照试验。尽管文献足以证实康复服务可改善临床和功能能力结果，但对情绪、与视力相关的生活质量（QoL）和健康相关的 QoL 的影响尚不明确。有一些关于特定干预措施效果的良好数据，但几乎没有关于儿童、工作年龄人群和其他人群的结果的有用数据。也没有关于成本效益的报告。总的来说，精心设计和充分报告的研究数量少得可怜；视觉康复研究需要更高质量的研究。我们强调了研究设计和报告的注意事项，并提出了未来的研究议程。
