I would treat with an anti bacterial such as Furazolidone, or Furaloid, and medicated food such as Krill soaked in Kanamyacin (any antibiotic will have to be mixed down with R/O) or perhaps the Jungle medicated foods. Full treatment is 10 days to two weeks

If the overall color around the eye is light colored give it a shot, but if the color is dark or bloody please euthanize the animal. That is a hemoragic swelling and is often incurable by the time you are witnessing sypmtoms, and is a miserably painful way to die. Best of Luck, Prof M
