title: Quantification of palpebral fissure shape in severe congenital blepharoptosis.
abstract: OBJECTIVE
  To measure palpebral fissure morphology in patients with severe congenital blepharoptosis.
  
  
  METHODS
  The palpebral fissure shape of 20 patients (30 eyes) with severe congenital blepharoptosis (levator excursion < or = 4 mm) was quantified with digital image processing in a cross-sectional design. Several variables related to the morphology of the palpebral fissure were measured: (a) upper and lower eyelid curvature, (b) palpebral fissure angle, and (c) position of the upper maximum and lower minimum eyelid contour.
  
  
  RESULTS
  Patients with severe congenital blepharoptosis often show a moderate degree of antimongoloid palpebral fissure orientation and eyelid drooping that is greater temporally than nasally.
  
  
  CONCLUSIONS
  Contour adjustment in severe congenital blepharoptosis surgery is better when it is not centered on the midline, but rather has a slight lateral displacement.
