fanfic eye descriptions...

I've wondered in the past about the peculiarities of eyes in fanfic, but I just read a passage describing eyes with "ice and ichor" and I was like wtf? Isn't ichor, like, pus or something? I know it's originally from some Greek mythology thing or other, but still. Anyway, regardless of the potential nuances of "ichor" I might be missing, I was just grossed out. Eyes like ice and pus?! Ick. Also, it didn't much sound like the voice of the POV character either.
