Can Restylane or Juvederm filler that was injected in upper cheeks, right below tear trough area migrate to the eyes?

Filler can migrate rarely, but more often is massaged up into an area by the doctor as they provide the treatment molding it into position.  Sometimes can be pushed to high, up into the eyelid area.  If this is the case it can be dissolved with Vitrase.  Sometimes it's because it was injected too superficially in the skin, causing a ridge.  We usually try to inject the majority of the product on the bone to minimize contour abnormalities.  Blindness is extremely rare and cause when the filler is injected into a vessel that supplies blood to the back of the eye.  It is not from product "moving" at any time after the injection was performed.  However if you are having visual issues consult an ophthalmologist immediately because this rare adverse event is possible with injections around the eye.

It is unlikely that you caused any problems but it is always best to allow the doctor who injected it to massage it.  Best of luck
