I acknowledge the deterioration of Itachi's eyes, yet he is still confirmed to see chakra at the moment of Kirin. Also, as @Cyberian said earlier, after the initial blurry vision, Itachi's eyes fluctuate from clear to blurry after Tsukuyomi use. Indicating still functional vision. And let's not forget, the entire fight Itachi still managed to more than keep track with Sasuke, Sasuke's jutsu and shuriken.

@Jason

If you know you can't dodge an attack, the next thought you must have is how to counter or block the incoming attack. Which in the case of Itachi is using Susanoo. Again, it's not shown when exactly Itachi used Susanoo. Unless you have proof stating otherwise? Would Sasuke still have used the attack if Susanoo was up beforehand?

Note: I realize that me claiming plot, is probably the reason for Itachi's Susanoo usage.
