Introduction. marcus gunn pupil (mgp) is the term given to an abnormal pupil showing aberrant pupillary response in certain ocular disorders. in literature, the term is often used synonymously with marcus gunn phenomenon or relative afferent pupillary defect (rapd). [1] after exposure to bright light, a normal pupil constricts. [2].
