Can fillers cause eyelid droop? (photos)

I had Botox around my eyes and in my forehead. I did not notice a droop, however when I went back 3 weeks later I had juvederm plus injected into my cheeks. That night my right eyelid was almost half way closer, the next day it opened up again. Can fillers cause eyelid droop? I'm inclined to think it was the fillers not the Botox. However you can see more of my right eyelid then my left which makes me question if it was the Botox. Will this go away or could a nerve possibly been hit?
