How about:
She was staring at him silently,the tiny veins in her eyes swollen.with bloodshot eyes.
My problem with it was that the sentence goes on to say that the tiles had turned dark with blood, so they're not actually white at the time he's looking at them. I assumed alpacinoutd was trying to contrast the usual colour of the tiles with the colour they now are. If that's the case, he usually considers the tiles to be "sickly white". I find that odd.

Her eyes were lifeless. She was staring at nothing at all.

I failed to point out that it was not only a comment but a suggestion.
