"The Walking Dead" showrunner Scott M. Gimple addressed the possibility of bringing Carl's injuries to the screen and how the show tries to strike a balance with the comic book source material during an interview with Entertainment Weekly.
"We don't know if anybody's losing their eye," Gimple said. "This is not 'A Christmas Story'... There are some things we can't do that were in the comic, [like] Rick losing his hand."
"There are other things we can and will do," Gimple shared. "There is a balance to be struck. If it is stuff that's really important to serve the character, we need to try and do it. It's also just if we can pull it off on a consistent basis in a great way. There's stuff we can do, there's stuff we can't do. I would never tell you what it is."
In "The Walking Dead" #83, Carl was shot in the eye during a walker attack. He survived but bears the scars of the injuries, using cloth and occasionally an eye patch to cover them up. Likewise, Rick has lost his hand in the comics, but that injury has never been translated to the screen.
