Amblyopia is the loss of parallelism between the eyes and asymmetry in the movement of the eyes when looking at a certain point. Amblyopia is one of the most common eye diseases and statistics indicate that 4% of people develop amblyopia.
The squint may be permanent or temporary.
Learn about the causes of around the eyes in adults and children, the types and accompanying vision disorders, and the latest methods of treating amblyopia in Turkey, under the supervision of a cadre of the best eye surgeons and their accessories.
Ophthalmology in Turkey has developed significantly in recent years, and it has become one of the leading countries in the field of ophthalmology.
Amblyopia is the failure of the eyes to maintain proper alignment and work together as a team. Amblyopia may always affect the same eye or may alternate between the two eyes (alternating strabismus). To prevent double vision in cases of congenital strabismus, the brain ignores signals from the deviated eye, causing Amblyopia.
Definition of strabismus
Amblyopia is a visual defect that causes the eyes to move in a non-parallel and unbalanced way so that the visual axes do not meet at a unit point, which causes diplopia and double vision for the patient.
The eye has six muscles responsible for moving them in different directions, the muscles of the eyes work in a natural way in a symmetrical way to maintain the balance and symmetry of the movements in both eyes, as the eyes look together towards the object to be seen and the two axes of vision meet at one point and with the help of the brain the two images coming from the eyes are merged in the form of a triple unit image Dimensions This is a complex process that takes place in precise coordination of the brain.
Strabismus is one of the most common diseases Estimates About 13 million people have amblyopia in the United States of America today.
It can be classified according to the direction of the deviated eye: strabismus shapes
- Esotropia: the eye deviates inward toward the nose.
- Exotropia is the deviation of the eye outward towards the ear.
- In the case of hypertropia, its deviation is upward.
- In the case of hypotropia, the deviation of the eye is downward.
Types of crossed eyes
There are two main types of squint:
1. Comorbid strabismus:
In this case, the strabismus angle is constant (the extent of the deviation of the eye) in all directions of view.
2. Incomitant strabismus:
The angle of strabismus varies with different direction of view, it may result from paralysis or weakness of the eye muscles.
Amblyopia occurs in all age stages and often appears in childhood. The child's internal strabismus appears in the first months of life, while Accommodative estropia affects the child at the age of two to three years and is caused by farsightedness.
Amblyopia that manifests with age is called acquired strabismus and is the result of weakness in one or both eyes, or paralysis of one of the ocular muscles for some reason.
3. Occult amblyopia (segments):
The squint does not appear except in cases of stress or when covering the other eye during the medical examination, then the hidden strabismus turns into an apparent strabismus due to fatigue as in the evening time and disappears in the morning upon awakening.
This type leads to clouding of letters and words, blurred vision and severe headache after working for two hours.
Some babies are born with a wide bridge of the nose and a fold of skin above the inner corner of the eye, giving the appearance of strabismus.
This condition may recede at the age of six months.
What are the causes of amblyopia?
The causes of injury vary from one case to another, and in certain cases the cause remains unknown. Here are the most important causes of strabismus:
- Weakness of vision in one eye (moderate to severe long-sightedness, the difference in refractive power in one eye in relation to the other eye, or due to less common problems such asto cushion congenital).
- Inflammatory conditions such as meningitis and diabetic neuritis
- Cerebral vascular lesions such as cerebral aneurysms.
- Down's syndrome
- Hydrocephalus is a structural defect that results in the accumulation of fluid in the brain.
- brain tumors;
- brain attack.
- An injury to the nerves responsible for moving the eye muscles (congenital or acquired).
What are the symptoms of amblyopia?
Strabismus has many different symptoms:
- Visual fatigue: redness and burning in the eyes, headache
- Difficulty reading and a decline in the child's academic level
- Determined by eye movements
- Sometimes strabismus may be associated with ptosis of the upper eyelid.
The diagnosis of strabismus in children is made during the routine visit to the doctor, where an eye examination is conducted at each visit to the pediatrician, but in the event of complaints of strabismus symptoms, visual impairment or any other eye disorders at any age, a full eye examination must be performed by the ophthalmologist.
What is a squint test?
The strabismus test or the so-called corneal light reflex The doctor directs the light perpendicular to the patient's pupil.
This test diagnoses strabismus.
What are the complications of strabismus?
Strabismus results in many visual, morphological and sometimes psychological complications:
NSfor visual complicationsAmblyopia can lead to a disturbance in vision, such as diplopia. One of the main complications of strabismus is the emergence of amblyopia That is, lazy eye that results from the brain neglecting the images coming from one of the eyes.
In most cases, strabismus causes an aesthetic disorder in the appearance of the face, and sometimes it may lead to psychological disorders in the sufferer.
Methods of treating amblyopia?
Treatment methods for strabismus vary according to the causative factor, and treatment can include: Using eyeglasses or contact lenses To fix an extension to see if it was the cause, treatment amblyopia Which may be a cause and a consequence of strabismusCovering the healthy eye with a patch To stimulate the affected eye. Sometimes, a procedure may be required Surgery To the affected eye muscles in order to correct their balance.
The basic principle of strabismus correction operations is:
- Delaying the attachment of the strong muscle to the eyeball, that is, bringing it back in order to weaken the muscle's ability to stretch.
- Shortening of the weak muscle (ie the muscle strain) in order to strengthen it.
This is done in amounts that vary according to the angle of strabismus determined by the doctor.
General anesthesia is used for most children, while it is performed for adults under local anesthesia. The type of anesthesia depends on the age of the patient and the presence of health diseases in addition to his preferences.
After surgery, it is normal for the white sclera of the eye to turn red after surgery.
It can take several weeks or sometimes months for the redness to go away.
The eyes are usually blurred and painful when moving.
The pain usually improves after a few days depending on the exact surgery that was performed.
The final result appears four to six weeks after the strabismus operation. Children under the age of 10 may need to repeat the operation to maintain the best results, and in some cases prism glasses may help to adjust the movement of the eyes together.
There is a modern treatment method based on Botox injections, this method is effective in simple cases of strabismus.
Some may resort to using prisms and orthoptic exercises as a complementary treatment to surgery in certain cases, such as intermittent lateral strabismus.
Exercise therapy for strabismus
This method is used to treat lateral strabismus during near vision. A simple exercise can be done as follows:
Holding a pen in the hand and slowly approaching the nose with a fixed eye on it until the occurrence of diplopia, then repeat this exercise several times a day and for a period of weeks until the distance at which he suffers from the occurrence of diplopia is reduced.
Unfortunately, muscle exercises are beneficial for a temporary period and must be repeated from time to time in order for the absence of symptoms to continue.

Strabismus cannot be prevented, but early diagnosis protects the child from complications.
