Giant Papillary Conjunctivitis and Droopy Eyelids?

The droopy eyelid (ptosis) may or may not be related to the GPC.  If the GPC has resolved and the ptosis has persisted, then it is unlikely to go away.  This may require ptosis surgery which involves tightening the muscle responsible for lifting the eyelid.  This is different than upper blepharoplasty, which simply removes skin from the upper eyelid and doesn't actually raise the eyelid.  See an oculoplastic surgeon for evaluation.
