A<unk>  <unk> , also known as a Marcus Gunn pupil, is a medical sign observed during the swinging-flashlight test whereupon the patient's pupils dilate when a bright light is swung from the unaffected eye to the affected eye. The affected eye still senses the light and produces pupillary sphincter constriction to some degree, albeit reduced. Depending on severity, different symptoms may appear during the swinging flash light test: Mild<unk>  will presents as a weak pupil constriction initially, after which dilation continues to happen. When<unk>  is moderate, pupil size will remain, after which it dilates When<unk>  is severe, the pupil will dilate quickly
