Amblyopia is a defect that affects the direction of eye movement. So there is a difference in the movement of both eyes or one of them when looking at a certain point, so one of them looks at this point in a straight direction, while the other looks in a direction away from the intended point. To understand the mechanism of strabismus, you must first know how the eye moves.

There are six muscles around the eye responsible for moving it in the direction of the object to be seen, based on signals sent from the eye to the brain to be translated and determine the direction of this object.

And then the eye is moved towards this object based on the information sent in the form of nerve signals responsible for moving the eye muscles in the direction of this object.

When can the symptoms of amblyopia be detected or noticed?

The age period from 3 months to 4 years is the period in which the eye is developed to perform its function, and it is normal for a physiological deviation in the first six months of birth, which disappears after that.

And as soon as I continue after that, it indicates a defect in the eye muscles or an injury to the brain, which is responsible for moving the eye muscles, and at that time, the eyesight is always deviated.

Causes of amblyopia

Most of these cases have no clear or specific causes, but there are some factors that contribute to its development, such as:

Some syndromes of birth defects of Mongolian children.

The genetic factor in the family also plays a major role in many cases.

The presence of organic diseases in other parts of the eye, such as diseases of the retina or the opacity of the lens of the eye with cataracts.

It may occur after some types of surgeries for the treatment of long-sightedness or short-sightedness.

Some cases of low vision, which are left for a long time without correction, cause deviation of sight.

Some direct injuries to the eye or eye muscles during or after childbirth.

Interpretation of the occurrence of amblyopia

The so-called double image occurs, and the person with deviation sees two different images, as one of the eyes looks at the object to be seen in a straight direction and the other deviates in a direction up, down, inward or outward. The affected person’s brain begins to ignore one of these two images and loses vision in both eyes.

It also loses its ability to distinguish the distance or proximity of objects.

Because it is normal for the eyes to look at an object in one direction, and the brain has one three-dimensional image. Therefore, when you ignore one of the two images occurs lazy eye.

Persistent strabismus that appears at all times and is outwardly noticeable.

Intermittent strabismus, which appears at times and disappears at other times.

The hidden type of strabismus also, which appears only during a medical examination of the eye or with fatigue, and can also be divided according to the direction of the deviation of the eye.

The acquired type that some may suffer in old age as a result of poor vision in one or both eyes.

Types of strabismus

Medial or internal strabismus

It is a strabismus resulting from the deviation of the eye inward. It is the common type of strabismus in children, and children with internal strabismus do not use their eyes together

Early surgery is usually necessary to reposition the eye. During surgery, the doctor adjusts the tension on the muscles of one or both eyes.

Where the doctor moves the point where the inner muscle meets the outer wall of the eye to the back of the eye

. This adjustment reduces the attraction of the eye inward and allows it to move more freely outward.

Another way is to shorten the external muscle to allow the eye to move outward.

Adaptive amblyopia

This type of strabismus is spread among children with farsightedness at the age of two years or more, when the child is young and has farsightedness.

His attempt to focus his gaze on nearby objects leads to internal strabismus.

Eyeglasses help remove the burden of focusing on objects close to the eye.

This causes the eyes to return to their normal position, and special eye drops and ointments or prism lenses help to correct the position of the eye.

Lateral or external strabismus

It is a strabismus resulting from the deviation of the eye outward. It appears when the child strains his eyes in an attempt to focus his eyes on distant objects.

Lateral strabismus appears only from time to time, especially when the child is stray, tired or sick.

How often the child’s parents may notice that one of his eyes is deflected outward when facing bright sunlight.

Although eyeglasses or prisms with eye exercises may help correct the position of the eye, surgery may be necessary.

How is strabismus diagnosed by an ophthalmologist?

The doctor examines the eye to determine whether the deviation is true or false. This appears when the patient is asked to look at a certain point and note the direction of eye movement.

Once the movement of the eyes is sound and equal, this indicates that it is a false deviation of vision and this may be due to the widening or narrowing of the eye opening, but it is not a true strabismus.

But if the movement of the eyes or one of them is improper, the doctor performs examinations and other tests of the eye to make sure that the existing deviation is the only symptom in the eye and there are no other symptoms accompanying it in the rest of the eye.

Once it is confirmed that there are no other accompanying symptoms, the type and degree of deviation is determined.

Complications of strabismus when diagnosis and treatment is delayed

Atrophy or lazy eye.

double vision

Timing of the neck toward the tilted position to maintain a single image view.

Affect the outer aesthetic shape of the face and eyes.

Deviation of sight may be a symptom of eye tumors, which delay treatment leads to death or blindness.
