iso- (equal) + -metr- (measure) + -opia (vision). Literally, the measure of vision is equal. The opposite of isometropia is anisometropia in which the two eyes have unequal refractive powers. Anisometropia is a serious concern in newborns and young children because it can lead to amblyopia (impaired vision in one eye). With a major degree […]
