A 25-YEAR-OLD woman woman with quadrantanopia in both eyes was examined using blue-on-yellow perimetry; the disorder corresponded with plaque detected on magnetic resonance imaging (MRI). She had had multiple sclerosis for 5 years. She had a visual acuity of 1.0 in both eyes. Goldmann perimetry showed normal visual fields in the right eye, but in the left eye abnormal points were sometimes found in the center within 30° with use of the Humphrey field analyzer. The patient was followed up 3 times a year using the white-on-white perimetry of the Humphrey field analyzer (model 750, Carl Zeiss, San Leandro, Calif). Perimetry revealed abnormal points in the left superior quadrant of both of her eyes (Figure 1). The patient showed left superior homonymous quadrantanopia on blue-on-yellow perimetry in both eyes (Figure 2). An MRI scan revealed plaque in the right temporal lobe (Figure 3). The patient's visual field defects corresponded with the lesion detected by MRI.
