Hypertropia is a type of squint (which is also known as strabismus and as heterotropia). Recall that a squint is an abnormal alignment of the eyes.

Hypertropia is the term used to describe the type of squint (abnormal alignment of the eyes) in which one eye - it can be either the right-eye, or the left-eye - looks upwards in situations in which one would usually expect both eyes to be directed other than upwards, e.g. both eyes looking towards a specific test object.

Terms used to refer to the main forms of squint include:

  • Horizontal: Convergent Strabismus (also called Esotropia)
  • Horizontal: Divergent Strabismus (also called Exotropia)
  • Vertical: Hypertropia (an eye looks upwards)
  • Vertical: Hypotropia (an eye looks downwards)
  • Eyes twisted clockwise or anticlockwise relative to each other Cyclotropia.
