esophoria

 [es″o-for´e-ah]
heterophoria in which there is deviation of the visual axis of one eye toward that of the other eye in the absence of visual fusional stimuli.

es·o·pho·ri·a

(es'ō-fō'rē-ă), Do not confuse this word with exophoria.
A tendency for the eyes to turn inward, prevented by binocular vision.
Synonym(s): esodeviation (1)
[G. esō, inward, + phora, a carrying]

esophoria

/eso·pho·ria/ (es″o-for´e-ah) deviation of the visual axis toward that of the other eye in the absence of visual fusional stimuli.

esophoria

[es′əfôr′ē·ə]
Etymology: Gk, eso, inward, pherein, to bear
the latent medial deviation of the visual axis of one eye in the absence of visual stimuli for fusion. Also called cross-eye. Compare esotropia, exophoria. esophoric, adj.

es·o·pho·ri·a

(es'ō-fōr'ē-ă)
A tendency for the eyes to turn inward, prevented by binocular vision.
[G. esō, inward, + phora, a carrying]

esophoria

A latent tendency for the eyes to turn involuntarily inwards. When a person with esophoria has one eye covered, that eye will turn inwards. As soon as the cover is removed, the eye straightens and single binocular vision is restored. Compare EXOPHORIA.

esophoria (E, ESOP, SOP, eso)

Turning of the eye inward from the active position when fusion is suspended. If symptomatic, treatment may be by means of base-out prisms, plus spherical lenses or visual training (Fig. E5). See convergence excess; divergence insufficiency.

Test the patient for near esophoria (with myopic correction; for example, using the Maddox wing test).
Varying degrees of success have been reported for both bifocal and progressive addition lenses; in some cases success has been limited to subjects with large near esophoria, (20) large accommodative lags, (21-22) or rapid myopia progression rates.
AC/A = accommodative convergence-to-accommodation, eso = esophoria, exo = exophoria, Hyper = hyperphoria, NA = not applicable, NRA = negative relative accommodation, Ortho = orthophoria, PD = prism diopter, PRA = positive relative accommodation, SD = standard deviation, SEM = standard error of the mean.
Practitioner may consider a base-out prism for an esophoria which doesn't respond to refractive correction, or base-in prism for older patients with exophoria at near.
This is why, on average, the normal heterophoria is a small degree of esophoria for distance vision and exophoria for near vision (Figure 1).
For example, the optometrist may cure a decompensating esophoria by correcting the underlying hypermetropia.
3) In esophoria, Percival's criterion is more useful, which states that the two fusional reserves should not be markedly different: the divergent fusional reserve should be more than half the convergent reserve.
Divergence-exophoria (in an attempt to overcome this, some individuals may demonstrate a compensatory esophoria in an attempt to drive the necessary accommodation)
There are, of course, occasional cases where low plus lenses are indicated, for example cases of decompensated esophoria with a high AC/A ratio, or cases of accommodative insufficiency.
There is no consistent evidence of a predisposition towards any particular type of heterophoria (exophoria, esophoria, hyper/hypo- phoria or cyclophoria) in children with reading problems.
The slowness of this readjustment may also apply to convergence, leading to symptoms of decompensated esophoria with distance fixation.
