anisometropia
Anisometropia ( ) is the condition in which the two eyes have unequal refractive power. Each eye can be nearsighted (myopia), farsighted (hyperopia) or a combination of both, which is called antimetropia. Generally a difference in power of two diopters or more is the accepted threshold to label the condition anisometropia.
In certain types of anisometropia, the visual cortex of the brain will not use both eyes together (binocular vision), and will instead suppress the central vision of one of the eyes. If this occurs often enough during the first 10 years of life while the visual cortex is developing, it can result in amblyopia, a condition where even when correcting the refractive error properly, the person is still not correctable to 20/20.
The name is from four Greek components: ''an-'' "not," ''iso-'' "same," ''metr-'' "measure," ''ops'' "eye."
Estimated 6% of subjects aged 6 to 18 have anisometropia.
