Application of contrast sensitivity in clinical neurology

This thesis is devoted to one new diagnostic technique called spatial contrast sensitivity (CS) measurement, to study visual function. This technique provides a much more comprehensive measure of visual efficiency than a standard acuity score. The visibility of objects depends not only on their size, but also on their relative brightness with respect to the background. Spatial contrast sensitivity measurement takes into account the contrast necessary for an object of any size to be detected. For its proper application in clinical neuro-ophthalmology, knowledge about the principles underlying human spatial contrast sensitivity is required
