Three patients with optic tract lesions, incomplete homonymous hemianopias, and good vision in both eves are presented. All three had a Marcus Gunn pupil in the eye with temporal field loss (eye contralateral to the tract lesion). This pupillary sign may serve to differentiate acute optic tract from acute ge-niculostriate lesions when the characteristic infrageni-culate optic atrophy has not had time to develop.
