Visual field defects in multiple sclerosis

Abstract

Visual fields were examined by means of Friedmann visual field analysis (VFA) and by static perimetry (SP) in 37 clinically definite multiple sclerosis patients. In the asymptomatic group (i.e., patients who never had any symptoms suggesting involvement of the visual pathways) VFA was normal in about half of the eyes tested, while approximately three quarters of the eyes that could be examined by SP showed visual field defects. Patchy relative defects in the intermediate visual field were the most frequently encountered visual field defects.

Visual outcome following optic neuritis: A 5-year review

“…[1,10] After resolution of optic neuritis, almost all patients show some signs of optic nerve damage and even when a patient's acuity recovers to 20/20, abnormalities frequently remain in other measures such as contrast sensitivity, color vision, and visual field. [11][12][13] Visual loss may be subtle or profound and may occur over hours (rarely) to days (most commonly). The nadir is usually about 1 week after the onset.…”
