 (ăm′ĭ-trō′pē-ə)
n.
An eye abnormality, such as nearsightedness, farsightedness, or astigmatism, resulting from faulty refractive ability of the eye.

Dado que los resultados obtenidos en el presente informe no tuvieron uniformidad en los metodos de medida ni en la definicion inicial de cada alteracion visual u ocular, las comparaciones con otros estudios se hacen muy dificiles; sin embargo, a pesar de estas consideraciones, en Latinoamerica, la mayoria de estudios sobre prevalencia de errores refractivos tambien han identificado al astigmatismo como la ametropia mas prevalente.
Ametropia (a condition of refractive error) is defined as a state of refraction, when parallel rays of light coming from infinity are focused either in front or behind the retina after passing through the diopteric power of the eye when the accommodation is at rest.
