title: [Congenital ptosis associated with fatty infiltration of levator eyelid muscle].
abstract: OBJECTIVE
  To quantify the fat in the levator muscle of patients with congenital ptosis, as related to clinical and epidemiological aspects of this disease.
  
  
  METHODS
  Twenty-two levator muscle samples of the superior eyelid from patients with congenital ptosis were morphometrically evaluated with aim of establishing a relationship between the fat quantity and age, sex, ptosis degree and levator muscle function.
  
  
  RESULTS
  According to our results the fat in the levator muscle of patients with congenital ptosis is not related to gender or epidemiologic aspects.
  
  
  CONCLUSIONS
  Fat amount in the levator muscle from congenital ptosis is not related to age, sex, ptosis degree or levator muscle function. Other studies will be necessary to show the real alterations in the levator muscle related to eyelid ptosis.
