Yes. Codiene, as an opiate can cause pupil constriction. This usually only happens at higher, recreational doses.
Non-responsive pupils are often a sign of brain trauma, and are usually a sign of a concussion.
no
Wellbutrin is an anti depressant, but it does have some potential side effects
Yes.
I am an adult and I started to take Ritalin 4 days ago. Usually I have dilated pupil, but with Ritalin they are quite constricted. I looked around in my text books and it is supposed to be the opposite to pupil are supposed to be more dilated. I also took effexor last month and my pupils were extra dilated (almost completely black). Yep I am not a professional, but it is very strange. Nevertheless even if with Ritalin my pupils are constricted my eye are very sensitive to light. My own theory will be that in some person Ritalin will increase the eye sensibility to light and than limit the amount by closing the pupil. Makes sense for me but I will still look around.
loss of flow of blood, constricted arteries
Restricted, constricted, or irritated airways cause wheezing.
yes, as will all opioid medications and/or substances
No, because it can cause seizures.
At night, the pupil dilates to let in more light. Astigmatism is a distortion in the cornea that causes different focal lengths for light passing through different parts of the cornea into the lens. With a small aperture (constricted pupil), the differences do not cause noticeable blurring; just as in a camera, a small aperture gives greater depth of field. At night, when the aperture is larger (dilated pupil), the eye has less depth of field, so the imprecise focal length of the eye causes the image to be noticeably blurred.
The dilator muscle which makes the pupil larger and the constrictor muscle which makes the pupil smaller.
