Research progress of contrast sensitivity detection / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

@#Contrast sensitivity(CS)has been widely studied in the research of ophthalmology and optometry. Compared with visual acuity(VA)test, CS assessment can fully and accurately reveal the state of visual function, which has become an important indicator for the prediction, diagnosis of eye diseases and for the evaluation of the disease progression and therapeutic effect. To improve the accuracy of CS measurement, CS detection methods have been constantly improved and innovated, mainly including objective examination and subjective psychophysical examination. Both methods have their advantages and limitations and the main target population is slightly different. With the development of the current Internet Plus, the CS detect software based on computer technology has been successively developed by many research institutions, which provide more convenient detection methods. Therefore, this paper reviews the visual standard design, measurement requirements and main applicable characteristics of common CS detection.
