The suggestion seems to be that it requires the Mangekyo to awaken the ability but not to use it. I'd also note that while the abilities of the Mangekyo are shown to do damage to the eyes, the Susanoo seemed to cause Sasuke pain throughout his entire body, further evidence that the Susanoo is more than a power of the eyes.

The Susano'o is a Visual Jutsu of the Mangekyo Sharingan. So by that defintion, no it is not just an ability that comes with the Visual Prowess. But still I thought you would at least need active Visual Prowess for a Visual Jutsu, be it the Susano'o or Amaterasu or whatever.

Sasuke also went blind from using the Mangekyo Sharingan after his fight with Danzo but once he did, his Susano'o fell apart, seemingly for good. And whilst Madara would have had more Chakra when he used it without his eyes, that would not have been the case for Itachi who had just fought to the death with Sasuke and drugged himself. So like...?
