title: Contrast sensitivity function as a diagnostic tool in low vision.
abstract: In this case report, a patient's visual loss associated with both cataract and senile macular degeneration is described. The contrast sensitivity function (CSF) as well as Retinometer and Visometer findings indicate that the additional visual loss over a year's time was lenticular, rather than retinal, in origin.
