Dr. Stuart Hickerson answered

Specializes in Family Medicine

Pupils: Pupil dilation or mydriasis can occur with anything that will cause increased sympathetic tone or adrenalin. Nerves, excitement, fright, flight are all things that will dilate the eyes. Caffeine, decongestants eye drops can all dilate the eyes.

Dr Iwata and another doctor agreed
