Unilateral blepharochalasis.

True blepharochalasis occurring in young adults and associated with recurrent bouts of eyelid swelling and eventual lid laxity is an uncommon entity. We report the case of an 18-year-old woman who had a nine-year history of unilateral blepharochalasis. A skin biopsy specimen that showed the absence of stainable elastic tissue confirmed the clinical impression, and appropriate surgical correction was carried out.
