Detection of Quadrantanopia in Multiple Sclerosis with Frequency Doubling Perimetry

Abstract

We report the case of multiple sclerosis with quadrantanopia revealed by Frequency doubling technology (FDT) version 3.0, which corresponded to the lesion detected by MRI. A 26-year-old woman with multiple sclerosis complained of blurred vision. MRI demonstrated a high-intensity lesion around the trigone of the left lateral ventricle. Humphrey white-on-white and blue-on-yellow perimetry detected few abnormal points in the right quadrant area, but a depression in that area. FDT version 3.0 revealed a markedly right superior homonymous quadrantanopia. FDT was useful for the detection of quadrantanopia in a patient with multiple sclerosis, as compared with conventional automated perimetry.
