anisometropia

Anisometropia exists when there is a difference in the power between the two eyes.

Gross anisometropia is the difference of more than 2 diopters between the eyes.

One study estimated that 6% of those between the ages of 6 and 18 have anisometropia.

One cause of significant anisometropia and subsequent aniseikonia has been aphakia.

Frequently, amblyopia is associated with a combination of anisometropia and strabismus.

For some patients the removal was only performed on one eye, resulting in the anisometropia / aniseikonia.

Vision loss can occur and is associated with strabismus, refractive errors, and anisometropia.

Refractive amblyopia may result from anisometropia (unequal refractive error between the two eyes).

Refractive: by anisometropia (high degrees of nearsightedness, farsightedness, or astigmatism in one or both eyes)

For those with large degrees of anisometropia, spectacle correction may cause the person to experience a difference in image magnification between the two eyes which could also prevent the development of good binocular vision.
