Abstract
Temporal contrast sensitivity was measured in patients with optic neuritis and anisometropic amblyopia. In optic neuritis, attenuated sensitivity was detected at all frequency ranges; its degree was more severe than that of retinal diseases even when visual acuity was the same. At the convalescent stage, the low-frequency sensitivity was restored first, and high-frequency loss was observed even when the visual acuity was restored to 1.0. Two amblyopic patients showed attenuated sensitivity at high and intermediate frequency ranges, and in 1 case all frequency sensitivity attenuated. Three other patients showed normal sensitivity. By occlusion of the nonamblyopic eye, recovery of sensitivity was observed in 1 patient, whose visual acuity improved.
