have you seen the vet? I keep russians too, swollen eyes are USUALLY a sign of Respiratory infection, if he is not eating, it means it is pretty advanced, he will need antibiotics to survive. I do not claim to know what is wrong with your tortoise, but mine is currently in the hospital tank after a vet visit. mine are kept outside and with a f****d weather this year this got an RI, looks like this except without the sores, the sores mean a definite infection, also, take him outside, let him enjoy the morning sun, also since he is not eating, neither is mine, give him soaks in V* or tomato (even better) juice. It feeds him a little bit as they absorb though claoca so much. good luck, i will not be checking how much anger and disagreement this comment will provide, but my best goes out to you and your boy
