STRABISMUS

It is a disorder in which the two eyes do not line up in the same direction because of the inability of the eye muscles to work in coordination. This deviation can occur in any direction, towards the inside or the outside, up or down.

 
It is present in about 4% of children under 6 years of age. And besides being an aesthetic problem, when it is present in children under 5 years of age, impacts the vision of the deviated eye, a condition known as amblyopia, or lazy eye.


 
CAUSES

  • Nervous system disorders, as alteration or injury in eye muscles.
  • Refractive errors that have not been corrected.
  • For example, the forced use of eyeglasses.
  • Family history sometime associated with infections, tumors, fetal distress, emotional factors or traumas.
  • In adults, as result of illness, cataracts, impact or trauma.

 


SYMPTOMS

  • Deviation of one eye or lack of alignment when focusing objects at different distances. The eyes can be seen moving to the inside or the outside.
  • Less visual acuity in one eye with respect to the other.
  • Abnormal positions of the head (lean to the right or to the left)
  • Problems to calculate distances and reliefs (lost of binocular vision)
  • Double vision at early stages.

 


TREATMENT

Treatment should start as soon as possible to be able to ensure a good development of visual acuity and to increase the probabilities of a normal visual function of both eyes (binocular). FUDEM recommends setting up an appointment with a specialist to begging treatment.

 
Treatment can include:

  • Eyeglasses or contact lenses: prescribed to enhance focus capacity and help with visual acuity problems.
  • Patches: In children, an eye that is not aligned in a proper manner could not mature visually. If it is not corrected, there might be a permanent lost of vision (amblyopia). The patch over the normal eye forces the use of the affected eye, boosting visual development.
  • Medications: Prescription eye drops and ointments that make vision blurry (generally enlarging the pupil and making the eye not to focus correctly)
  • Contact lenses: to blurry the vision of the good eye to stimulate vision with the weak eye.
  • Surgery: Eyes can be realigned with surgical intervention.
