    Pupil Hippus Anyone? (Pupils constricting/dilating)

    Does anyone get bad exaggerated hippus where your pupils go back and forth from constricting and dilating? This is regardless of light hitting them. The pupils will keep oscillating back and forth. I swear I can even feel it do this and my vision will get shaky/jerky when its bad. I don't know...
