A couple of months ago when Alice was beginning to outgrow his baby hide, which is stone, it always looked like he was cramming himself into it, especially after a meal. One night it appeared one of his eyecaps looked similar to the one in your pic. I posted here and was informed by everyone who replied that it sounded like retained eyecaps. However, he had not looked like that following his most recent shed, which had been a couple of weeks previously. Within a day or so, it was completely gone. I thought the same thing you are thinking...that he scratched his eye or made a temporary indention on it by pressing up against the top of that hide. Unless someone else here has a better explanation, I wouldn't worry about it too much just yet.
