I don't know if this is exactly the same case as yours, but a while back I thought I noticed a dent in my fire female's eye. All my temps and humidity were fine, and no stuck eye caps so I thought it could have been an injury. Well I let her be for a few days (I'm not saying to do this, I just did, it may have been right or wrong) and the next time I checked on her the eye was back to normal. Not sure if that helped, that's just what happened to me.
