In page 8 there is another pic of sasuke from itachi's point of view. He's getting blinder by the second.
So it seems that for next chapter Itachi might be completely blind after using the amaterasu.
EDIT: It seems that Itachi is blinder from one eye than the other. 50-40 vision perhaps?
EDIT EDIT: Don't forget Sasuke's *that*jutsu , my guess is that he would use it now that Itachi has used his most powerful technique.
