What would cause a retro-bulbar abscess? May 14 pers/hym mix had one but she was strictly indoor and very healthy. I read that some abscesses are caused by wounds which she did not have. All of a sudden one day her 3rd eye-lid got puffy and then her eyeball buldged out. It was drained, unfortunately we think she threw a clot and passed away as she was coming out of anesthesia.
Sometimes they just occur and we do not know why. sorry about your cat. vetcare
