Entire attack with pupillary reaction and fundus image. The swinging flashlight test shows a relative afferent pupillary defect, ie, an asymmetric optic nerve or severe retinal abnormality, in the right eye. The fundus is seen as an inverted direct image through a slitlamp microscope and a noncontact convex lens. The retinal arteries and veins are narrow diffusely, and the disc is pale. In the late phase, the retinal vessels are dilated and the disc is hyperemic. The relative afferent pupillary defect has resolved.
