VISTECH contrast sensitivity and pattern-VEP in multiple sclerosis patients.
In 12 known multiple sclerosis patients with a visual acuity of 7/10 or better in both eyes, optic nerve function was tested by means of contrast sensitivity measurement (VISTECH technique) and pattern-VEP. The results were compared with those of an age related control group. The VISTECH contrast sensitivity measurement is a useful tool in evaluating the remaining visual discomfort after the resolution of an optic neuritis. However, to detect a subclinical optic neuritis, the pattern-VEP is more sensitive.
