Convergent strabismus

Convergent strabismus: causes, symptoms and treatment

Convergent strabismus, also known as convergent strabismus or esotropia, is a vision disorder characterized by abnormal eye position. In this condition, one or both eyes look inside the nose rather than parallel to each other or in the same direction. Convergent strabismus usually appears in early childhood and can have various causes.

One of the main causes of convergent strabismus is improper functioning of the eye muscles responsible for moving the eyeballs. Normally functioning eye muscles allow both eyes to look in the same direction, providing binocular vision. However, in convergent strabismus, the muscles in one of the eyes are weakened or not properly controlled, resulting in a convergent eye position.

Symptoms of convergent strabismus may include:

1. Converging eye position when focusing on close objects.
2. Blurry or double vision.
3. Eye fatigue when reading or doing close work.
4. Headaches or a feeling of tension in the eyes.
5. Lack of depth perception when viewing 3D images.

Diagnosis of convergent strabismus usually involves an examination by an eye doctor who performs various tests, including vision measurements and evaluation of eye coordination. Once the diagnosis is confirmed, the doctor determines the degree of strabismus and decides on the need for treatment.

Treatment for convergent strabismus may include:

1. Using glasses or contact lenses to correct vision.
2. Therapeutic exercises to strengthen and improve eye muscle control.
3. Using special devices, such as patches or blocking lenses, to stimulate the weakened eye.
4. In some cases, surgery may be required to correct the position of the eye muscles.

It is important to note that the success of treatment for convergent strabismus depends on many factors, including the age of the patient, the degree of strabismus, and the timeliness of treatment. Early contact with an ophthalmologist increases the chances of effectively restoring normal eye function.

In conclusion, convergent strabismus is a vision disorder that requires attention and treatment. Early consultation with a doctor and proper treatment can help improve the position of the eyes and restore binocular vision. If you or your child has symptoms of convergent strabismus, it is recommended that you immediately consult a doctor for professional advice and diagnosis.

Strabismus descending

Strabismus **converging** is a **disbinocular** type of disbinocular form of strabismus. Accompanied by a constant or periodically appearing deviation of the visible object outward from the side of the eye that is closer to it. Distant landmarks deviate towards the more distant eye and the fixed eyelid lying opposite it. The development of this form is associated with improper functioning of the external muscles and a lag in the development of mobile muscles that form the points of binocular alignment, which are more labile and plastic. An extreme manifestation of **esophoria** is often observed with concomitant strabismus as a result of weakness of the extrinsic muscles. Subsequently, it becomes monolateral.

Without timely and systematic treatment for convergent strabismus, the deviation of the eyeballs increases with age in a child, all disorders intensify, binocular functions are depressed, the developing skull loses its craniocaudal size, and pressure from one of the frontal lobes of the brain on the other leads to compensatory partial monophoxy.[ 1]

**Correction of strabismus** of this form requires constant joint actions of the ophthalmologist and the educator for the development of basic vector visual functions and gaze fixation. The main effort is aimed at
