The loss of the parallelism of the eyes with each other is called strabismus. Shifts can be hidden, intermittent or continuous. Hidden shifts are detected only during the examination and the feeling of depth, which is the highest level of binocular vision, is normal. The shifts generally start intermittently and gradually change over time. While inward shifts generally turn into continuous shifts in months, this period may be very long in outward shifts.
Although there is no specific genetic transition, strabismus, laziness in the family are more common in those with high refractive error. In strabismus caused by muscle paralysis, the patient has a condition such as high blood pressure, diabetes, vascular disease and head trauma, which usually causes paralysis in adult age. Such shifts can also be congenital. In strabismus that are not caused by muscle paralysis, high hyperopia, myopia or astigmatism can cause slipping. Sometimes it is seen as special types of strabismus (such as Duane syndrome, Brown syndrome) with certain clinical features.
Strabismus and lazy eye may be related to each other as a cause / effect. Continuous slipping of the same eye causes lazy eye, while sometimes lazy eye can lead to strabismus.
Treatment with glasses in some strabismus is very successful. Strabismus improves when the child wears glasses. As the age gets older, it can gain the ability to control it, and when it is removed, the eye will no longer slip. Sometimes, the glasses partially helps, in this case, in addition to the glasses, strabismus surgery is required. If there is lazy eye, closing treatment is continued. The treatment is surgical in cases that do not improve with glasses. It is done by replacing or shortening the muscles causes the problem and increasing their strength. Strabismus is seen as an aesthetic problem at first, but it can become a problem that can lead to serious vision loss when not treated. The earlier the treatment is started in children, the greater the chances of success. Treatment is also possible in adulthood. Adults can also adapt the surgeries, as in children, and adapt to using both eyes together.
