Mongoloid slope of the palpebral fissures

DA: 54

Developmental anomaly information

Definition: A mongoloid palpebral slant exists when the outer canthus is higher than the inner canthus. Patients with myelomeningocele demonstrate a consistent abnormality in the configuration of the palpebral fissure. What appears to be a mongoloid slant in reality may be a straightening of the lower lid margin, which gives the illusion of a mongoloid slant. These patients frequently demonstrate a pattern usually associated with overaction of the superior oblique muscle, and sometimes with dissociated vertical deviation. The diagnosis of myelomeningocele can be suspected in most cases simply by looking at the lid configuration.


  • Mongoloid slanted the palpebral fissures,
  • eyelid cleft
  • down-slanting eyes
  • palpebral cleft
