A child or infant with anisometropia is typically prescribed the full refractive difference between the 2 eyes, regardless of age, presence or amount of strabismus, or degree of anisometropia. Anisometropic amblyopia is frequently present and may require occlusion therapy. Bilateral amblyopia occasionally occurs when there is significant hyperopia, myopia, and/or astigmatism in both eyes. Refractive amblyopia is less common with bilateral myopia because these patients have clear near vision.
