-metropia Also -metropic.

A condition of the eye.

[Greek metron, measure, plus ōps, eye.]

This ending appears in a few medical terms relating to the ability of the eye to form images: hypermetropia (Greek huper, over, above) is long-sightedness; anisometropia (Greek anisos, unequal) refers to an inequality in the refractive power of the two eyes; ametropia (Greek a-, not, without) is faulty refraction of light rays by the eye, as in astigmatism or myopia; emmetropia (see en-2) is the normal refractive condition of the eye, in which the rays of light are accurately focused on the retina. Associated adjectives are formed in -metropic (emmetropic, hypermetropic).
