No. If the concussion is moderate then the pupils probably won't dilate. pupils usually dilate due to swelling in the brain.
When the pupils become large, the term for this is dilated pupils. (Some people just say "dilated eyes", although this isn't a precise way to conceptualize it.)
"Undulated", no.
Yes... or no. Dilated pupils either signify excitement or fear.

One of the signs doctors look for in pronouncing a person dead is "pupils fixed and dilated".
they will have dilated eyes, seem really energetic and talk in an excited way. If they are bouncing off the walls with dilated eyes, they're probably coked out!

Concussions often cause the eyes to be different. Check the WebMD website to see if any other symptoms exist that you were unaware of: http://www.webmd.com/brain/tc/traumatic-brain-injury-concussion-overview
Sleepy cat.
The part of the eye that dilates is known as the pupil. It sometimes dilates when you look at someone that you are physically attracted to. This happens because of a chemical reaction in your brain. Pupils also dilate according to how much light is present to allow better vision. Pupils are dilated when there is little light available. You can test this out by looking in a mirror where there is a lot of light (your pupils should be very small because allowing too much light in damages the eyes). Then look into a mirror where there is less light and your pupils will have dilated. During a concussion, a person may also have dilated pupils. I'm not sure why, but probably as a result due to the force of impact sustained by the head.
