Anisometropia

Anisometropia (anisometropia; Greek anisos - unequal + Greek metron– measure + opos, ops - eye; synonym: heterometropia) is a condition in which the refraction of the left and right eyes is not the same.

The following types of anisometropia are distinguished:

  • Eponymous (homonyma) - characterized by varying degrees of the same type of eye refraction;
  • Axial (axialis) - due to the different length of the optical axes of the eyes;
  • Presbyopic (presbyopica) - due to varying degrees of weakening of the accommodation of the eyes in the elderly;
  • Simple (simplex) - unlike anisometropia, in which there is emmetropia in one eye and ametropia in the other;
  • Simple hypermetropic (simplex hypermetropica) - simple anisometropia, in which there is hyperopia of one eye and emmetropia of the other;
  • Simple myopic (simplex myopica) - simple anisometropia, in which there is myopia in one eye and emmetropia in the other;
  • Divergent (heteronyma) - characterized by different types of refraction;
  • Refractive (refractionis) - due to the different refractive power of the optical system of the eyes;
  • Complex (heteronyma composita; synonyms: mixed anisometropia, antimetropia) - heteronymic anisometropia, in which different types of ametropia are observed on the left and right eyes.
