Abstract
Grating contrast sensitivity has long been used in the study of visual physiology [1], and more recently in the study of ophthalmological disorders [2,3]. While Snellen acuity tests determine only the highest detectable spatial frequency at maximal obtainable contrast, grating tests measure the minimum detectable contrast over a wide range of spatial frequencies, more closely simulating the visual demands of daily life. Traditionally, contrast sensitivity is defined as the reciprocal of the minimum detectable contrast, and a plot of contrast sensitivity vs. spatial frequency is a representation of the contrast sensitivity function (CSF). Many factors are known to influence the CSF, including pupillary diameter and the refractive power of the eye [1], age of the observer [2], and retinal disease [3]. In this paper we report measurements of the CSF in a population of 42 juvenile onset diabetics, and 20 age matched non-diabetic controls.
