I'm the first to say I'm not a doctor or pretend I know medical stuff, but the eye shit can be something small and end up being a Bisping situation. That's the nature of MMA and the risk they take to step in the cage. It's one of those things we'll never know. I don't think even the more extreme foul, the more damage done, probably most damage is by legal shots.
Still think UFC needs to start treating these things like they did LHW division.... New champ out for awhile? Vacate and let the division move on, you get a titleshot on return.
Well time for UFC to say... "look what happened with Jiri or Hill, they couldn't defend in a timely manner, they got another titleshot once they returned". These damn HW fights are like lining up the planets and stars to get them to fight 2x a year like it's a miracle. It sucks it's from a foul, but the body breaks randomly and we've already seen Aspinall out for his knee injury before. This guy never won a title, out of his hands of course, but still it's not like Islam or Jones where he's some legendary champ that deserves leeway.
