9D43 Impairment of contrast vision

International Classification of Diseases for Mortality and Morbidity Statistics, 11th Revision, v2024-01

Contrast sensitivity refers to the ability to distinguish small differences in brightness between adjacent surfaces. Peak Contrast sensitivity refers to the smallest differences that are discernible for large stimuli. For smaller objects, such as those involved in many Activities of Daily Living, contrast sensitivity interacts with visual acuity and visual field. Better contrast makes smaller details visible. The visual field is larger for stronger stimuli.
