Strabismus<\/span><\/strong> is a disorder that is more common in children but also occurs in adults. If left untreated, it not only affects the person’s <\/span>eye health<\/span><\/strong> , causing the quality of life to decrease and the inability to perform some professions, but also prevents them from socializing due to aesthetic concerns.<\/span><\/p>\n

<\/span>So, what causes strabismus,<\/span><\/strong> one of the oldest known disorders ? <\/span>What are the types of strabismus? By what methods is <\/span><\/strong> strabismus<\/strong> , also called <\/span>eye misalignment<\/span><\/strong> , treated? Will an untreated strabismus<\/strong> go away on its own over time? The answers to all these questions are given under the relevant subheadings below.<\/span><\/span><\/strong><\/span><\/span><\/strong><\/span><\/p>\n

Causes of Strabismus<\/span><\/h2>\n

Although the exact cause cannot be stated, it is possible to mention some factors that cause <\/span>strabismus :<\/span><\/strong><\/span><\/p>\n

The eyes move with the synchronized work of six muscle groups, two of which are oblique and four rectus muscles. The reason why <\/span>strabismus<\/span><\/strong> usually occurs is the disruption of harmony between these muscles, whose strength increases or decreases. Also, some diseases that affect the control center area of \u200b\u200bthese muscles in the brain (such as hydrocephalus, Down syndrome, cerebral palsy) also <\/span>cause eye misalignment<\/span><\/strong> .<\/span><\/p>\n

High fever and accidents in childhood, etc. <\/span>Strabismus<\/span><\/strong> may also occur after trauma. In addition, if the eye has a refractive error such as <\/span>hypermetropia<\/span><\/strong> and is advanced, this may cause <\/span>eye misalignment when the child tries to clarify the vision.<\/span><\/strong><\/span><\/p>\n

Some diseases experienced by an expectant mother during her pregnancy may also cause <\/span>strabismus in the baby<\/span><\/a><\/strong> . Additionally, the baby is born prematurely or with low birth weight, has a seizure, or experiences some postnatal trauma, which are also <\/span>among the causes of eye misalignment<\/span><\/strong> .<\/span><\/p>\n

Common <\/span>causes of strabismus<\/span><\/strong> include structural disorders (neurological, functional or abnormal conditions in the muscles) and some eye-related disorders (such as glaucoma, cataracts). <\/span>Strabismus<\/span><\/strong> may also be a reflection of high blood pressure, diabetes, and some tumors that develop in the brain or inside the eye (Strabismus, which appears suddenly, requires detailed examination, as it may be a sign of the presence of a tumor).<\/span><\/p>\n

Apart from all these reasons, it is known that <\/span>genetic factors<\/span><\/strong> play a role in strabismus. Although there is a high risk of inheriting <\/span>eye strain from the next generation, <\/span><\/strong><\/span>strabismus does not occur<\/span><\/strong> in every child who has a strabismic member(s) in their family .<\/span><\/p>\n

Types of Strabismus<\/span><\/h2>\n

Strabismus<\/span><\/strong><\/a> has been classified in different ways by approaching it from different angles.<\/span><\/p>\n

Nonparalytic and paralytic strabismus, whether there is muscle paralysis (stroke) or not; non-accommodative, accommodative and partially <\/span>accommodative strabismus<\/span><\/strong> , based on the relationship of strabismus with accommodation (the function of the eyes to adapt and focus); monocular and alternating strabismus, whether the deviation is always seen in one eye or in one right and one left eye; constant and intermittent strabismus, whether strabismus is always present or not; congenital and acquired strabismus, age of onset of strabismus; comitant and incompatible strabismus, depending on the angle of deviation (whether it changes according to the direction of gaze); Manifest and latent strabismus are classifications made by looking at whether the strabismus is clearly noticeable from the front.<\/span><\/p>\n

Apart from these classifications, there is also a classification based <\/span>on the direction of strabismus<\/span><\/strong> . Accordingly, <\/span>eye deviations<\/span><\/strong> are divided into groups as inward, outward, upward, downward and others.<\/span><\/p>\n

Eye Turning Inward (Esotropia)<\/span><\/h3>\n

<\/span>Among the types of strabismus<\/span><\/strong> performed by looking at the direction of deviation, the most common one in children is inward deviation. Strabismus in this group, also called <\/span>esotropia<\/span><\/strong><\/a> , is encountered in approximately half of <\/span>the strabismus cases<\/span><\/strong> seen in childhood (especially in children between the ages of 1.5 and 4) .<\/span><\/p>\n

Non-accommodative, accommodative and partially accommodative are prominent among the types of esotropia. When <\/span>the eye shifts inwards<\/span><\/strong> , there is a high probability that hypermetropia refractive error will also exist. Esotropia that develops due to hypermetropia is called <\/span>accommodative esotropia<\/span><\/strong> , and such <\/span>inward shifts<\/span><\/strong> are encountered more frequently than other types.<\/span><\/p>\n

<\/span><\/strong>Treatment with glasses is the first method used in accommodative esotropia<\/strong> . If the shift continues, even partially, despite treatment with glasses, this is called <\/span>partial accommodative esotropia<\/span><\/strong> . Even if the refractive error is corrected with glasses, if there is no regression <\/span>in the inward deviation<\/span><\/strong> of the eyes, there is <\/span>non-accommodative esotropia .<\/span><\/strong><\/span><\/p>\n

Even though there is no refractive error, <\/span>inward deviation<\/span><\/strong> of the eye may occur. Especially in adults, esotropia caused by nerve paralysis may be encountered. These patients can be treated with neurotoxin injection.<\/span><\/p>\n

<\/span>Inward shifts that<\/span><\/strong> appear until the baby is 6 months old are defined as <\/span>infantile esotropia<\/span><\/strong> (congenital inward slippage). (Infantile esotropia can sometimes occur between 6-12 months). This type <\/span>of strabismus<\/span><\/strong> can be corrected by surgical intervention before the baby reaches the age of 2, because <\/span>binocular vision<\/span><\/strong> can only be achieved with this method. In other words, treatment with glasses is often inadequate for such cases.<\/span><\/p>\n
