I had Restylane fillers below my eyes. 2 weeks later I have a burst blood vessel in one eye. Should I be concerned? (Photo)

Its unlikely that the injections under your eyes led to the development of your broken blood vessel, otherwise known as a subconjunctival hemorrhage.  Nonetheless, it is always a good idea to have your eyes checked out by an ophthalmologist.

Restylane is a great product for injection in the face and I doubt that two weeks later could cause the blood vessel to burst.  However, I would consult an ophthalmologist to determine the cause of the broken blood vessel to make sure. I also prefer Belotero in many cases under the eyes since it is such a fine hyaluronic acid filler. For the best cosmetic result please consult a board certified dermatologist with a great deal of experience with tear trough injections. 

It is unlikely that 2 weeks out and no complications from the Restylane would suddenly result in a burst blood vessel in the eye. I believe it's coincidence. Best to have your eye checked out though, but I really doubt the Restylane caused anything. "This answer has been solicited without seeing this patient and
