Strabismus is a condition in which the gaze position of the eyes is not in one direction, but both visual axes have shifted in different directions and cannot coincide at a single point.

It is common, affects about 4% of children, but can also develop in adults.

Strabismus that occurs within the first 6 months of life is called ’infantile strabismus’.

Most of the time, the eyes are not parallel in the newborn,inward and outward shifts are observed in the eyes.Therefore, it is difficult to detect the shift during this period.

Usually the position of the eyes is 3.it becomes fixed per month.If the mother expresses that the child’s eye is shifting during this period, this situation should definitely be evaluated. In addition, cataracts, eye tumors or neurological diseases can manifest themselves with strabismus, so a specialist ophthalmologist should be consulted.

In the family history; Does anyone have eye problems in the family, the presence of problems such as high degree of glasses, slippage, low vision are questioned.

It should be questioned whether the pregnancy passed normally, fever, rash diseases (viral diseases), medications taken, whether the baby is term (in terms of retinopathy of prematurity). It is important how the shift is noticed, whether it is continuous, how old it has been since, whether it is observed in one eye or in both eyes from time to time, whether it develops after any specific event, for example, trauma, convulsions, whether it is noticed after an event. And it should be known whether any treatment has been performed for slipping before, the numbers of his glasses, if any, whether there is closure or surgical treatment.

First of all, visual acuity should be measured separately from both eyes,

Now, with the developing technology, we are able to take much more comfortable measurements with advanced devices such as plusoptix in babies who previously had difficulty measuring eye refraction. In addition, thanks to the video feature of plusoptix devices, we can more easily examine eye movements and deviations from the optical axis and diagnose them more easily. This device can be used to measure strabismus in refraction measurement in children from the age of 1 month. On the subject of eye laziness, it can provide us with preliminary information about optical axis opacities.

If we suspect a pathology in the visual pathways, a VEP (Visual evoked potential) visual evoked potential test can be performed.

The first symptom of a shift is that the eyes do not focus on the same point, but signs such as closing one eye in the sun, tilting or turning the head may be the result of a shift.

During infancy or preschool period, every child should be eye examined for possible eye problems (such as strabismus, lazy eye, refractive errors or cataracts, glaucoma, intraocular tumors). As a false belief among the public, it is thought that the shift in infancy will improve over time with growth, but this is a mistake strabismus never decelerates on its own with growth. But in cases where we call false strabismus in children, where the root of the nose is wide and there is no slip, which leads to the appearance of a slip, the appearance of a slip improves with the development of the nasal bone over time, which incorrectly suggests that the slip has improved. In such cases, an ophthalmologist should definitely be seen for differential diagnosis and correct diagnosis.

In addition, if there are people with strabismus or laziness of the eyes in the family, the child should definitely be shown to the ophthalmologist at the age of 1.

Amblyopia is a common condition in strabismus patients. Amblyopia, popularly known as eye laziness, is a condition in which visual acuity decays without an organic disorder of the eye or visual pathways.

After the diagnosis of strabismus is made, the causative factor should first be determined and treatment for the cause should be initiated. The first treatment to be performed is the complete correction of the refraction defect, if any. This solves the problem in most patients. If there is eye laziness, treatment for this should be planned. If the gliding still continues despite the glasses, surgery can be planned.

Our goal in the treatment is to ensure the deceleration of both eyes by using them together without negatively affecting the visual development. After a detailed eye examination, treatment is planned according to the cause of the slip.

The earlier strabismus treatment is performed, the higher its success will be. But in adult strabismus or in adults who have not been treated before, an increase in peripheral vision can also be achieved with surgical treatment, especially in adults.

Surgical treatment is not an alternative to glasses or closure, but glasses and closure treatment can continue after surgery.

What are the risk factors for strabismus?

1- The presence of a history of strabismus in family members increases the probability of strabismus in the more people and generations.

2- Premature birth, difficult birth or low birth weight, staying in the bathtub, history of oxygen therapy

3- Having asymmetry in the anisometropia between the two eyes or high farsightedness

4- Hydrocephalus (Collection of water in the brain)

5- Children with cerebral palsy and birth trauma
