The red eye has nothing to do with blood from my understanding. It is caused by RC cells which are entirely fictional. I don't think there is anything within Tokyo Ghoul to suggest that ghouls could have different coloured eyes.

I do know something that debunks your medical based ghoul and white eye idea but it could be considered a spoiler.
