The advances in treating blinding conditions often depends on the development of new techniques that allows early detection, treatment, and follow-up of the disease. Functional changes often precede structural changes in many retinal disorders. Therefore, detecting these changes helps in early diagnosis and management, with the intention of preventing permanent morbidity. The Retinal Functional Imager (RFI) is a non-invasive imaging system that allows us to assess the various functional parameters of the retina. The RFI quantitatively measures the retinal blood-flow velocity, oxygen saturation, metabolic demand and generates a non-invasive capillary perfusion map that provides details similar to a fluorescein angiography. All of these parameters correlate with the health of the retina, and are known to get deranged in retinal disease. This article is a brief review of published literature on the clinical utility of the RFI.
治疗致盲性疾病的进展往往取决于新技术的发展，这些新技术可以实现疾病的早期发现、治疗和随访。在许多视网膜疾病中，功能变化往往先于结构变化。因此，检测这些变化有助于早期诊断和管理，目的是预防永久性发病。视网膜功能成像仪（RFI）是一种非侵入性成像系统，它可以让我们评估视网膜的各种功能参数。RFI 定量测量视网膜血流速度、氧饱和度、代谢需求，并生成一个非侵入性的毛细血管灌注图，提供类似于荧光素血管造影的详细信息。所有这些参数都与视网膜的健康状况相关，并且已知在视网膜疾病中会出现异常。本文是对 RFI 临床应用的已发表文献的简要回顾。
