Neuro-ophthalmologic examination demonstrated visual acuity of 20/50 OD and 20/20 OS. There was a mild dyschromatopsia in the right eye and a 0.3-log unit, relative, afferent pupillary defect in the right eye. The remainder of the examination showed no abnormalities, with healthy optic nerves, no disc edema, and a cup-disc ratio of 0.2 in each eye. Automated perimetry (Humphrey Visual Field Analyzer, Program 24-2, Allergan Inc, San Leandro, Calif) showed a mild cecocentral depression in the right eye. The left visual field had a dense scotoma that looked like an arcuate defect emanating inferiorly from the blind spot and disappearing at the vertical midline (Figure 1). A dense scotoma that appeared to be a nasal step was also present. The patient denied any visual symptoms in the left eye and the nerve fiber layer and optic disc showed no abnormalities.
