Droopy eye due to orbital floor fracture? (Photo)

Based on the photo, I am assuming that the left eye was the traumatized eye? When was the surgery?The most likely issue here is that there is residual enophthalmos (sunken eye) on the left side. This maybe due to an enlarged eye socket bony that was not fully repaired with the surgery, or it could be due to atrophy (shrinkage) of the eye socket fat that sometimes occurs with trauma. This condition can be repaired. Measurements can be made clinically by an Oculoplastics surgeon that can help tease out the problem here. 

You might be referring to lower eyelid retraction or something else. Best to see an oculoplastic specialist for evaluation. See following link too. Skype consult available.

Repairing the orbit fracture causes significant orbit swelling.  This will affect the eyelids. It is essential to give this time to heal.  When the dust settles, you may nor may not feel that you need to have the eyelids fixed.
