The girl's pupil certainly isn't terribly deformed. Certainly she can use it for all sorts of seeing. And it's deformity is only visible on close inspection...she is of course also missing irises, an affliction that caused no end of ridicule in her pubescence.
One should note: She is not heiling Hitler, nor is she hailing a cab. Methinks she is simply showing off her extremely long fingers. So long in fact that she is able to scratch her brain through her nostrils when it is itchy. Why it gets itchy I don't know.
