esotropia

 [es″o-tro´pe-ah]
strabismus in which there is manifest deviation of the visual axis of one eye toward that of the other eye, resulting in diplopia; called also cross-eye and convergent strabismus. adj., adj esotrop´ic.

(es'ō-trō'pē-ă),
The form of strabismus in which the visual axes converge; may be paralytic or concomitant, monocular or alternating, accommodative or nonaccommodative.
[G. esō, inward, + tropē, turn]

esotropia

[es′ətrō′pē·ə]
Etymology: Gk, eso + tropos, turning

Esotropia

strabismus

Nonparallel positioning or movement of the eyes—usually of the vertical axis—due to decreased binocular muscle coordination with loss of stereoscopic vision and inability to focus simultaneously on a single point.

Convergent strabismus Ophthalmology Strabismus characterized by a convergence of the visual axes. See Strabismus.

esotropia

Convergent squint, or STRABISMUS. Only one eye looks directly at the object of regard, the other being turned inwards. Esotropia in children calls for urgent treatment to avoid amblyopia. Compare EXOTROPIA.

Infantile esotropia syndrome and monocular OKN asymmetry
He called these associations the congenital strabismus syndrome, which is now known as infantile esotropia syndrome (IES).
This wedge depends on vergence angle and is maximised by high-angle esodeviations, implying that esotropia may be an 'adaptive' developmental response.
Most childhood strabismus is esotropia, which can be classed as fully accommodative (if the deviation is corrected with plus lenses), partially accommodative (if the deviation is lessened but not corrected with plus lenses) or non-accommodative (no hypermetropia or the deviation is not effected by spectacles).
2) An early interruption to binocularity, typically from infantile esotropia syndrome, often results in three clinical signs which persist throughout life, even if the visual axes are surgically straightened.
As many as 15% of patients with infantile esotropia may have infantile accommodative esotropia, nearly half of whom can be fully straightened with spectacles.
Esotropia with an onset after the first year of life will not be infantile esotropia syndrome and the chances of there being a significant accommodative element increase.
