人的视空间分辨能力,长期以来主要以视力来评价。但经实践,人们越来越感到这种指标的局限性,它不能全面,准确反映视形觉特性。近年来,国外用对比敏感度函数(CSF)来研究和评价视觉功能,已使视觉分辨能力的时空特性有重要进展,受到世界生理学和眼科学的广泛重视。国内,温州医学院已研究成功“激光视网膜——大脑调制传递函数测定仪”并报告了临床初步应用的结果。中科院生理所对整体人眼CSF进行了某些研究,但实际应用资料尚未报道。为探讨整
Human visual spatial resolution has long been mainly evaluated by visual acuity. However, after practice, people are more and more aware of the limitations of this indicator, which can not fully and accurately reflect the visual-visual characteristics. In recent years, the foreign use of contrast sensitivity function (CSF) to study and evaluate the visual function, has made the spatial and temporal characteristics of visual resolution have important progress, by the world physiology and ophthalmology wide attention. In China, Wenzhou Medical College has successfully researched the “laser retina - brain modulation transfer function detector” and reported the results of preliminary clinical application. Physiological Institute of Chinese Academy of Sciences on the whole human eye CSF conducted some research, but the practical application of information has not been reported. To explore the whole
