What is canthal tilt?

• Definition: Canthal Tilt refers to the angle of the line connecting the inner and outer corners (canthi) of the eye relative to the horizontal plane. It's a facial feature that influences the overall appearance of the eyes and face.

• Types: There are three main types of Canthal Tilt:

  • Positive Canthal Tilt: The outer corner of the eye is higher than the inner corner. This is often associated with a more youthful and alert appearance.
  • Neutral Canthal Tilt: The inner and outer corners of the eye are at roughly the same level.
  • Negative Canthal Tilt: The outer corner of the eye is lower than the inner corner.

• Aesthetics: Canthal Tilt is often discussed in the context of facial aesthetics and attractiveness. A positive tilt is commonly considered desirable, while a negative tilt can sometimes be perceived as tired or sad-looking.

• Factors Influencing Canthal Tilt: Canthal Tilt is influenced by:

  • Genetics: The primary determinant of canthal tilt.
  • Age: Canthal tilt can change with age due to the loss of skin elasticity and changes in facial structure.
  • Ethnicity: Some ethnic groups tend to have a higher prevalence of certain types of canthal tilt.

• Medical Considerations: In some cases, a significant Canthal Tilt (particularly a negative tilt) can be associated with underlying medical conditions, although this is rare. Also, it may be changed with blepharoplasty, also known as eyelid surgery
