Abstract:

Amblyopia is a developmental abnormality that is a consequence of abnormal visual experience early in life. Contrast sensitivity function (CSF) plays an important role in diagnosis and treatment of amblyopia. It has been suggested that the CSF characterizes amblyopia’s spatial vision deficits better than letter acuity does. From grating charts and letter charts to computer-based testing, as the research moves along, CSF measurements have been developed with high efficiency. Amblyopia therapies based on CSF have come a long way from circular activate machine (CAM) to perceptual learning. (Int Rev Ophthalmol, 2019, 43： 204-210)
