视网膜功能影像检查技术在视网膜疾病中的临床应用

Application of retinal functional imager in retinal diseases

新型的视网膜影像学技术能帮助我们更好地理解多种视网膜疾病的发病机制,如糖尿病视网膜病变、老年性黄斑变性、青光眼以及葡萄膜炎等。早期对这些疾病进行监测能够预防进行性视力丧失,同时在发展新型治疗方法上也起着重要的作用。视网膜功能影像检查技术是一种独特的非损伤性的功能性影像学检查技术。与目前临床上广泛使用的视网膜影像检查技术不同的是,视网膜功能影像检查技术不仅能显示视网膜结构上的改变,还能动态监测视网膜的功能状态和评估血流动力学参数,如监测视网膜血液流速、血氧状态等。本文即对这项视网膜功能影像检查技术在各种视网膜疾病中的应用进展作简要综述。

Newer retinal imaging technologies help us in understanding the pathogenesis of many retinal pathologies,such as diabetic retinopathy,age related macular degeneration,glaucoma and uveitis.Early detection of these retinal diseases can prevent the onset of progressive vision loss,and aid in the development of new treatment options.Retinal functional imager （RFI） is an unique and noninvasive functional imaging system.Unlike most of the available newer retinal imaging tools,the RFI not only shows retinal structural changes,but can directly monitor functional changes and measure hemodynamic parameters,such as retinal blood-flow velocity,oximetric state,etc.This article reviews the utility progress of RFI in various retinal diseases.
