microtropia

(redirected from small angle strabismus)

mi·cro·tro·pi·a

(mī'krō-trō'pē-ă),
Strabismus of less than 4 degrees, associated with amblyopia, eccentric fixation, or anomalous retinal correspondence.
[micro- + G. tropē, a turn, turning]

microsquint

A small-angle heterotropia, usually 10 dioptres or less, which, whilst associated with defective binocular function, cannot be treated. Microsquint is often associated with anisometropia; both predispose children to amblyopia. Children with microsquint are prescribed eyeglasses if they are anisometropic. Long-term follow-up is advised to detect and treat early amblyopia.

microtropia

(mī″krō-trō′pē-ă) [″ + trope, a turning]
Strabismus with very small deviation, usually less than 4°.

microtropia

A small-angled (usually less than 6-8 Χ in angle) inconspicuous strabismus which is not usually detected by cover test, either because the deviation is too small or because the angles of abnormal retinal correspondence and eccentric fixation coincide with the angle of deviation. There is usually amblyopia in the deviated eye and there may also be anisometropia. The patient with this condition displays nearly normal binocular vision without symptoms. Management usually consists of correcting the refractive error. Syn. microsquint; microstrabismus; small angle strabismus. See four prism dioptre base out test.
