Follow-Up: I have hooding which may be caused by orbital fat loss. Does sulcus appear to be hollow? Can it be corrected?

You do have a deep upper orbital sulcus on both sides with some excess skin.  An upper lid bleph to remove a crescent shaped area of skin from the upper lids with micro fat grafting of the upper orbital rim would look nice. 

Hi and thanks for your question.  You may have a lot going on with your eyes.  It's hard to tell without a profile view about the position of your globe (eyeballs).  Irrespective of this you do have excess upper eyelid skin which would benefit from an upper blepharoplasty.  Your upper eyelids do appear a bit hollow and upper blepharoplasty can help restore some volume if your surgeon does a very limited muscle excision.  Sometimes filler can also help but it's pretty risky in you because your so thin.  There wouldn't be much room for error and you would be a setup for lumps and bumps.  Hope this helps!
