Will pupils react with rocuronium?

Hence, the effect of rocuronium on dilated nonreactive pupils was suspected. After 4 h of the discontinuation of rocuronium, the pupils started to decrease in size. Furthermore, the size of pupils decreased to 2 mm, and the pupils became reactive to light 20 h after stopping rocuronium infusion.

Results Dexmedetomidine produced no change in pupil size and light reflex recovery time, increased the light reflex from 0.30 ± 0.14 to 0.37 ± 0.12 mm and significantly reduced pupillary reflex dilation by 72 ± 62%.

Does caffeine make your pupils dilate?

According to the outcome of this study, caffeine has paradoxical effects on the intrinsic muscles of the eye: dilating the pupils and increasing accommodative amplitude. This may account for the changes in some visual functions or vision-related task associated with caffeine intake.
