Video Transcript

  • Researcher: Christopher W. Tyler (City Univ. of London)
  • Visual neuroscientist Dr. Tyler examined Leonardo’s artwork and concluded that he suffered from a rare eye disorder
  • The eye disorder was identified as intermittent exotropia
  • Because the exotropia was intermittent, he could switch back and forth between 2-D and 3-D
  • Patients suffering from intermittent exotropia are able to switch between 2-D and 3-D vision by aligning the eyes accordingly
  • This study assessed 2 sculptures, 2 oil paintings, and 2 drawings created by Leonardo
  • Most paintings exhibit a consistent exotropic strabismus angle of −10.3°
