Strabismus Unilateral

Strabismus is a condition in which the visual axes of the eyeballs are unable to focus on a single image. This occurs due to improper functioning of the extraocular muscles or visual centers of the brain. Strabismus can be caused by various factors such as injury, infection or hereditary causes.

Depending on how many eyes deviate from direct gaze, symptoms may vary. Thus, in children, strabismus is most often partial and incorrect - healthy eyes tilt in different directions (for example, one eye looks straight, and the other looks to the side). In adults, strabismus is always one-sided. In both cases, strabismus is a cosmetic defect, but its unpleasant consequences can also arise due to the fact that the tilt of one eye leads to overload of this particular eye, so the vision in it worsens in comparison with the other eye. The brain receives incorrect visual images during convergence and accommodation, which are regulated by the eye muscles. He cannot process and differentiate them correctly. The gaze of healthy eyes during strabismus intersects as if both eyes are tending to the same point on the retina. However, due to unequal degrees of delay in the arrival of the impulse, the brain ignores information about something small, displaced further or closer than usual, otherwise it simply becomes confused by the discrepancy between the details and shape of the two images coming from each eye. Meanwhile, with very acute strabismus, one of the eyes is completely turned off from work, the ocular muscular system gets tired of it, then the patient avoids looking in the mirror, because he sees his reflection, for example, with a slanted eye from under his forehead. He often has head asymmetry and an asymmetrical face. The vision of strabismic patients is usually double, weakened both at distance and near. With age, symptoms of acute strabismus are observed at any age, even in adulthood. It all depends on how severe the damage to the eye or eyes was.
