tonic pupil is delayed weak constriction to light and also delayed dilation in dark :shock: specifically, in marcus gunn pupil, there is damage to the afferent limb of one optic nerve. shine a light in the affected eye, no dilation in either eye. shine a light in the unaffected eye, and both dilate normally.
the light reflex causes contriction of the pupil so if it dilates, means that it is not normal :arrow: paradoxical
