What is strabismus?
Strabismus is the loss or symmetry between the two eyes, in which case the depth of vision is lost.
Our eyes, which have a diameter of around 2.5 cm, are mobilised by six muscles at each side.
If one or more of these muscles are stronger or weaker than the others, symmetry is lost and cross-eye develops. Strabismus can be observed in one eye or in both eyes.
How is it diagnosed?
Diagnosis can be made by a comprehensive examination by a specialist ophthalmologist. In this examination, the visual acuities, refractive errors, angle of deviation and vision of both eyes are evaluated. Especially in infants, shifts that occur before the development of the nasal roots can mislead the family.
It is recommended that all children undergo visual examination before they turn four years old.
If there is a family history of strabismus or lazy eye, vision may be tested before. It should not be concluded that this is a condition seen only in children. It may also occur in adults. It can be seen in adults as a result of an accident or untreated lazy eye in childhood. The most common complaint in adult individuals is “double vision”.
What Are the Symptoms?
- Loss of the symmetry between the two eyes
- Eye watering
- Double vision
- Loss of three-dimensional image
- Blurred vision
- Head or face facing away
What Are the Types?
- Inward (Esotropia)
- Outward (Exotropia)
- Upward (Hypertropia)
- Downward (Hypotropia)
How Is It Treated?
The purpose of treatment is to maintain vision, regain symmetry of the eyes and provide vision with two eyes in order to provide depth is vision.
The diagnosis and treatment of strabismus is performed by our specialist physicians with technological devices at Düzey Eye Health Center.
It may be a sign of other diseases
Strabismus can be inherited or caused by refractive errors. Worse, however, it can also be a symptom of a major eye disease, nerve paralysis or some muscle disorders that impair vision. The second most common symptom of an intraocular tumor called retinoblastoma is strabismus. Sometimes the first sign of a mass in the head can be strabismus. Therefore, it should be remembered that strabismus may have some vital problems other than the eye. For this reason, a person who has slipped eye should definitely be evaluated by an ophthalmologist.
The first choice of treatment is the use of special eyeglasses. Shifts caused by refractive errors such as myopia and hyperopia usually corrects after wearing eyeglasses.
In cases that do not improve with the eyeglasses treatment, surgery is needed. Strabismus surgery is based on the necessary intervention to the problematic eye muscle. Longer eye muscle is cut and shortened. In general, patients can return to normal life in a day or two, and the success rate of this operation is very high. For more information please click here.
With botulinum toxin (botox) injection into the muscle causing the shift, symmetry of the eyes is ensured, but the treatment is effective for about 6 months and it is generally preferred in special cases such as nerve paralysis strabismus.
What is Hidden Strabismus?
It is the least known type of strabismus among the people. It is almost impossible to notice when the two eyes are open. However, if one of the eyes is closed and the other glides, there is a hidden strabismus
