Fig. 13. Sparing of the monocular temporal crescent. A 65-year-old man with left hemianopia from right medial occipital infarct. Fields show complete hemianopia within an eccentricity of 60°, but sparing of the temporal field beyond 60°, which is normally only perceived in the temporal field. This indicates a striate lesion with sparing of the retrosplenial portion of calcarine cortex. (From Barton JJS, Sharpe JA: Smooth pursuit and saccades to moving targets in blind hemifields.
