Filler or blepharoplasty to treat the lumps under my tear trough? (Photo)

I had lower lid blepharoplasty in May 2022. The procedure was relatively successful. And corrected some fat prolapse post thyroid eye disease. I have since had one filler treatment for hollowing in the tear trough (Juvederm). This was approx 8 months ago. I have recently noticed lumps under my tear trough (photo). The questions: are these likely to be as a result of fat redisposition during blepharoplasty or do they look like filler residue? What are treatment options?
