Pupils and Brain

  1. 0 I thought I had this straight, then I listened to a lecture today and feel confused again. When a patient presents with a left hemorrhagic stroke will the pupillary dilatation be on the contralateral side or the ipsilateral side?

    I thought the pupillary response would be on the same side (ipsilateral) as the injury, is this not correct?

    Depends on the location of the hemorrhage and the size. The pupils could be completely equal or unequal. Remember that Cranial Nerve 3 controls pupil dilation so follow the nerve path. Also, increased ICP will affect pupil dilation by compressing the nerve pathway.
