摘要视网膜血氧定量法是一种快速、无创的新型视网膜血管成像技术，用于测量视网膜主要动、静脉的血氧饱和度并进行量化分析，反映视网膜血氧新陈代谢情况，从而反映全身微循环状态，为医学诊断提供可靠依据。视网膜血氧饱和度可作为生物标记物应用于糖尿病视网膜病变、视网膜中央静脉阻塞、视网膜色素变性、青光眼和阿尔茨海默病等眼科及脑部疾病的诊断及严重程度的评估。

abstractsThe retinal blood oxygen quantification method is a fast and non-invasive new retinal vascular imaging technology, which is used to reflect the metabolism of retinal blood oxygen and the micro-circulation of whole body by measuring, analyzing and quantifying the blood oxygen saturation of the main arteries and veins of the retina. The circulation state provides a reliable basis for medical diagnosis. Retinal blood oxygen saturation can be used as a biomarker for the diagnosis and evaluation of ophthalmologic and brain diseases such as diabetic retinopathy, central retinal vein occlusion, retinitis pigmentosa, glaucoma and Alzheimer's disease.
