Your reaction to the filler product is very unusual and could be an allergic reaction. I have seen something like this only once before - a nurse I used to work with had massive swelling about two weeks after being injected with a hyaluronic acid filler and was placed on a course of steroids, which did result in a dramatic decrease in the swelling. Approximately one month later, the swelling returned and she went through another round of steroids; 2 months later, it happened again, another round of steroids; and then nothing since. She had had fillers at least twice before that with no reaction, but not with that particular brand. We did not treat her with hyaluronidase. Hopefully, your swelling will resolve in time. An allergic reaction would affect all areas that were treated equally - I am unsure if that is your situation or not, as the photo only shows the right eye. If the reaction is focal (only involving the right eye) then I would be more suspicious of a hematoma (blood clot) or infection. I am sorry you had this result, but these things do usually resolve themselves over time, but waiting can be quite frustrating.
