What is Strabismus?

Strabismus can be defined as losing the parallelism between the eyes. There are 6 extraocular muscles in both eyes. The lack or excess force in one or more of these muscle causes to strabismus. While one eye looks straight, the other may cross inward, outward, upward or downward. In some cases, this disorder is available in both eyes. Strabismus may be permanent or temporary according to its cause. There is not only one reason in the formation of strabismus. It may arise from different causes.

Early diagnosis is all important in the treatment of strabismus. When it is late for the eye examination, children may have low vision for life in addition to their aesthetical problems in their eyes. Even if children do not have any eye problem right after birth and in childhood period, they must certainly be examined by a specialist physician.

Causes of Strabismus?

There is not only one cause of strabismus. Troubled gestation period and birth, development of child and the diseases transmitted may cause to strabismus. Genetic susceptibility is influential in strabismus. If there is strabismus history in the family, the incidence rate of strabismus increases.

In strabismus cases seen in the childhood period, in a word following the age of 2, visual impairments are often the cause of strabismus. An inflammatory disease or a trauma (falling, operations, accidents) may cause to strabismus in children having this susceptibility.

The center dominating the movement of optic muscles is in brain and therefore paralyses in nerves may cause to sight loss as well. Accidents, head traumas, inflammatory diseases, hypertension and diabetes in advanced age may cause paralysis in optic tracts. In strabismus cases occurring in this way, treatment may vary according to whether or not the paralysis is permanent. Amblyopia in children must certainly be treated due to it will cause to double vision in advancing ages.

What are the Causes of Strabismus?

  • Loss of parallelism in eyes

  • Watering of eye

  • Pain

  • Headache

  • Double Vision

  • Loss of three dimensional vision

  • Blurred vision

  • Head and face to turn one side

A part of the strabismus cases in infantry and childhood period arise from pseudostrabismus. Pseudostrabismus is a misleading appearance occurring with the width of eyelids and nasal root. In order to illuminate this completely, an eye examination must certainly be made.

Crossing of the same eye constantly is a symptom that sight in that eye is lower and it is important. Therefore, infants and children with crossing on the one eye must be taken to eye examination.
