Contrast Sensitivity Function as a Diagnostic Tool in Low Vision

Key Points

This report aims to evaluate the contrast sensitivity function as a diagnostic measure for visual loss.
Descriptive case report of a patient with visual loss
Assessment using contrast sensitivity function, retinometer, and visometer
Comparison of visual loss over one year
Visual loss was identified as lenticular rather than retinal
Findings suggest a significant role for the contrast sensitivity function in diagnosing low vision conditions

Abstract

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.
