disturbed the position of the eyes characterized by the deviation of one or both eyes from the Central axis. Deviation occurs alternately. The projection of the objects to which looks people fall into the center area of each eye in the case of a symmetrical arrangement of the eye. Cortical sections of the visual centers responsible for the merger of acquired projections into one whole image binocular in nature. With the development of strabismus the merge process occurs. To protect from a split image Central nervous system posts an exception to the projection of the received eye with compromised position.

In the case of a long development of the disease in the absence of proper treatment the patient may develop a condition of amblyopia, in which the squinting eye will be completely excluded from the process of contemplation.


The reasons for developing strabismus, are different. The factors causing the emergence of diseases may be congenital or acquired. The causes of strabismus include

  • progress in human myopia, hyperopia or astigmatism, the degree of which is higher or equal to the average
  • injuries, paralysis, cuts
  • abnormal development and attachment of muscles responsible for eye movement
  • the development of diseases affecting the Central nervous system
  • a stressful situation
  • the transfer of infectious or somatic diseases
  • the presence of trauma
  • the process of a sharp reduction in the acuity of the eye.


The main clinical manifestation of strabismus is a violation of the principle of binocular vision in connection with a deviation of the eye from a symmetrical position. In the case of strabismus, the visual analyzer can not be combined projection received by each eye that leads to the exclusion of that image that gets the squinting eye.


There are two types of strabismus, based on the origin of the disease.

Friendly alternating strabismus deviation of eye to same distance. Studies have shown that the probability of the development of strabismus greater in those people who have ametropia and anisometropia, especially owners of hyperopia. Convergent strabismus is prevalent in farsighted people, and divergent strabismus myopic. The role of refractive error in the process of the development of strabismus depends on the severity of disorders of visual function.

Also according to experts, the concomitant strabismus can develop due to diseases of the nervous system, retina, differences in ocular anatomy congenital in nature.

This form of strabismus may occur as follows

  • after fixation of the gaze on a stationary object one eye deviated
  • the deviation may carry variable character
  • eye movements and remains fully
  • the squinting eye may suffer loss of visual ability.

Strabismus paralytic form of the disease, which decimated one eye. The main symptom of limited or no movement of the eyes towards the muscles of the affected lesions and deformities, as a result violated the principle of binocular vision, double vision appears. The reasons for the development of paralytic strabismus can be pathological processes in the nerves or muscles, disorders of muscle function. These disorders may be congenital or occur because of injuries, neoplastic processes, vascular system of the body.

With paralytic type of strabismus deviation of eye is not equal distance, perhaps double vision the visual image, the patient has to turn his head in the direction of the muscle which is affected, you may experience dizziness.

Strabismus in infants and children strabismus often it is paralytic in nature. In addition, paralytic strabismus may develop as a result of toxicity or trauma.

In addition to these there are also forms of vertical strabismus. In this form of the disease eye turns in relative to the vertical axis, that is, either up or down.

To the atypical forms of strabismus include those manifestations of disease that are caused by anomalies and pathologies in the development of the eye (are anatomical in nature). On the development of such types of strabismus is affected by the syndromes brown, Duane and others.

Moreover, strabismus can be divided into groups according to the time of appearance of the disease, according to involvement of the eyes relative to the origin of the disease, stability of variance and according to the types of deviations.


To confirm the diagnosis or refutation of, the patient undergoes a comprehensive examination of the entire visual system. To date, for these purposes, quite often used computerized diagnostic tools. A full examination of the visual system enables you to make the clinical picture of the patient’s condition and course of disease in General. Also has gained widespread tests that establish the status of binocular vision of man.


Strabismus in adults and children should be treated with minimal time delay after the beginning of the disease. The reason for this is that over time the visual ability of rejected eye is getting worse. This can lead to a complete suppression of the visual functions of the eye with a deflected position.

Therapeutic measures to eliminate the disease mainly include

  • correction of strabismus optical character. In this case, the correction of strabismus is done with the help of contact lenses or glasses that are used on the recommendation of the physician conducting the treatment of the disease
  • the procedure of hardware measures aimed at improvement of visual functions and visual acuity in both eyes of the patient
  • treatments and therapeutic measures for the development of the principle of binocular vision with the subsequent consolidation of the results achieved. Often resort to orthoptic and diploptic treatment measures and means
  • methods involving surgical intervention.

In most cases surgery for the treatment of strabismus is a means of cosmetic nature, because its implementation is rarely helps to restore binocular vision of the patient without additional measures. Swiftly when strabismus does not have a unique character for each case of the disease. The doctor should take into account the location features, and abnormalities of the muscles that hold the eye of the patient. For this reason, the decision about the form of transactions are accepted directly ahead of her performance. The main objective of the operation is the strengthening or weakening one of the muscles responsible for holding the eyeball. Surgery for strabismus may affect one or two eyes, depending on each specific case. Upon completion of the operation the patient is moved to a home setting, as the intervention is in the nature of a single day.
