CONTRAST SENSITIVITY DURING PROVOKED VISUAL IMPAIRMENT IN MULTIPLE SCLEROSIS

Academic Article

Abstract

  • Abstracts— Many patients with multiple sclerosis have subjective visual complaints that are intensified by exercise (Uhthoff's symptom). We report a case demonstrating the utility of contrast sensitivity testing in such visual complaints. Contrast sensitivity was measured before and after exercise in a multiple sclerosis patient with Uhthoff's symptom and in two healthy control subjects. A short exercise period reduced the patient's contrast sensitivity for some target sizes, but had no effect on his visual acuity; a longer exercise period produced a greater, more uniform loss of contrast sensitivity and also reduced visual acuity. Contrast sensitivities and visual acuities of the control subjects were not affected by exercise. Copyright © 1986, Wiley Blackwell. All rights reserved
