Which one of the following patterns of visual disturbance would be predicted to be demonstrable on examination of this patient?: (A) Inferior hemifield loss, (B) Temporal quadrantanopsia, (C) Uniocular blindness, (D) Macular sparing hemianopia
Answer is A. Answer A. Inferior hemifield lossDilated ophthalmoscopy of this left eye illustrates a nonrefractile plaque in the proximal superior retinal artery with retinal whitening in the superior macula signifying retinal ischemia. Superior retinal ischemia will result in a defect in the inferior visual field, as in this patient. A diagnosis of hemiretinal arterial occlusion was made.
