Sorry I can't tell that from your pricture.

As for the actual cut which I've had for ages and I've noticed it for well over a decade, I think I did have my eye operated on when I was really young, but I've never been told about it really. Was that cut placed there to help with my tear drainage or something?
I looked at the pictures and given this 2-D view I don't see any major differences but yes people do differ in the amount of fat (and therefore thickness) as we grow older. No a minor cut could not cause that to be permanent. with any trauma any were in the body there can be a temporary swelling
