In 1970 a 62-year-old physician with hypertensive vascular disease suffered a small infarction in the left optic disc, which left him with a subtle paracentral temporal visual field defect in that eye. In 1973 he had another separate and distinct episode in the same eye, which produced a dense lower nasal field defect. Careful Hruby lens examination of the disc under high magnification revealed focal arteriolar disease in the optic nerve head corresponding to the field defects, and fluorescein angiography confirmed these findings. The importance of differentiating ischemic optic neuropathy, hypertensive optic neuropathy, and temporal arteritis with optic nerve involvement is emphasized, and the therapy of each is discussed.
