What symptom is strabismus?

summary

Strabismus refers to the inability of two eyes to focus on the target at the same time. It belongs to extraocular muscle disease and can be divided into two categories: concomitant strabismus and paralytic strabismus. The main clinical features of concomitant strabismus are no eye movement disorder and equal strabismus in the first and second eye positions; Paralytic strabismus is limited eye movement, diplopia, can be congenital, can also be caused by trauma, or systemic diseases. What symptom is strabismus? Let's talk about it

What symptom is strabismus?

The eye position deviates inward. Congenital esotropia occurs from birth to birth. The deflection angle is usually very large. Acquired esotropia can be divided into accommodative and non accommodative. Accommodative esotropia often occurs in 2-3-year-old children. Children usually have moderate to high hyperopia, or abnormal accommodative cohesion and accommodative ratio.

Exotropia can be divided into intermittent exotropia and constant exotropia. Intermittent exotropia patients with good image fusion ability, most of the time the eye position can be maintained in the normal position by the image fusion ability, only occasionally in the sun or fatigue wandering time, the performance of exotropia. Some children also show that no matter how strong the sun is, they often close one eye. Intermittent exotropia often develops into constant exotropia.

The upward or downward deviation of eye position is less than esotropia and exotropia. The upward and downward deviation is often accompanied by head deviation, that is, compensatory head position. The stereoacuity was measured by stereoscopic quantitative pictures of synoptophore or Yan's random dot stereogram.

matters needing attention

Treatment of strabismus, first of all, for amblyopia, in order to promote good visual development of two eyes, followed by correction of deviation of eye position. Strabismus treatment methods include: wearing glasses, wearing eye mask cover, ortho training. Wearing eye mask is the main method to treat amblyopia caused by strabismus. Ophthalmic surgery involves relaxing (weakening) or shortening (strengthening) one or more of the extraocular muscles of one or two eyes. Mild strabismus can be corrected by prism. Ortho vision training can be used as a supplement before and after operation.
