Trial demonstrates edge contrast sensitivity as an indicator of visual function in low vision patients, indicating its clinical relevance.
The contrast sensitivity (CS) for a single edge appears to be a reliable indicator of the peak of the contrast sensitivity function (CSF). We propose that for general clinical practice and in the functional assessment of patients with low vision, the simple measurement of edge CS provides an adequate indicator of the peak of the CSF. We conducted a trial in which edge CS was measured in a routine clinic setting.
