What is the difference between dermatochalasis and blepharochalasis?

  • Dermatochalasis is the redundancy and draping of the eyelid skin in the aged face. It causes pseudoptosis when it progresses to the point that skin drapes over the upper eyelashes and causes visual field defects. Dermatochalasis may occur in younger people who have a familial predisposition for upper eyelid skin redundancy and/or orbital fat hypertrophy.
  • Blepharochalasis is rare variant of angioneurotic edema in which recurrent episodes of eyelid edema eventually lead to chronic changes in eyelid skin elasticity and pigmentation as well as upper lid ptosis. It should not be confused with dermatochalasis.
