> in fact, that's a part of what happens when you get atropine drops during an eye exam.
Atropine works by temporarily blocking the contraction of the muscle sphincter pupillae (which along with dilator pupillae is responsible for the contraction of the pupil). The cilliary muscle isn't involved. The rest of your comment stands, though.
It is my understanding that atropine (like scopolamine, cyclopentate, etc.) effectively paralyzes the ciliary muscles by blocking muscarinic receptors. This enables an ophtalmologist to measure the "true" refractive error of the eye.
Atropine is also a mydriatic agent (dilates the pupils) and this lets you better see the retina, but that's a different effect than the one I was referring to.
