Atropine 41-49 opsin 4 Homo sapiens 116-126 32168243-8 2020 Melanopsin-driven post-illumination pupil responses, achieved with either phenylephrine or atropine, did not significantly differ from each other (P > .05 for all). Atropine 91-99 opsin 4 Homo sapiens 0-10 32168243-10 2020 CONCLUSIONS: Dilation with phenylephrine or atropine resulted in similar enhancements of the rod/cone- and melanopsin-driven pupil responses, despite differing mechanisms. Atropine 44-52 opsin 4 Homo sapiens 107-117
