Astigmatism in children - mostly hereditary

astigmatism in children Astigmatism in children is not uncommon and is hereditary.The low degree of astigmatism in the majority of people remain undetected throughout life.Medium and high degrees of astigmatism can create serious problems for the child in the form of a backlog in the neuropsychological development and strabismus.


astigmatism in children

The normal cornea is shaped like a sphere.This ensures the correct surface of the cornea focus light rays on the retina produces a clear image of the object (focus).With astigmatism, the shape of the cornea is broken, the curvature of the surface in two mutually perpendicular cross-sections are different.The light rays that form the image of an object as it passes through a cornea refract differently, and so the image is blurry.

Astigmatism in children can develop at any age, but most often a child is born with it already.

Astigmatism - a congenital curvature of the cornea or irregular shape of the lens.In children, mostly found in the corneal astigmatism.Due to reshape the cornea refracts light it correctly and there is no focus on the retina, both in normal and in front of or behind it.

At irregular shape of the cornea can be a set of meridians along which a beam of light.But there are usually two main meridian - vertical and horizontal, are always located perpendicular to each other.As of these meridians identify different types of astigmatism.If the primary pathology is a vertical meridian, the astigmatism Astigmatism - lenses, glasses or surgery? Astigmatism - lenses, glasses or surgery? considered a direct, on the horizontal - reverse.

In addition, astigmatism in children can be nearsightedness, farsightedness or mixed.Nearsighted (myopic), astigmatism of the child, in turn, is divided into simple and complex.Simple myopic astigmatism myopic astigmatism - a combination of astigmatism and nearsightedness Myopic astigmatism - a combination of astigmatism and nearsightedness characterized by the fact that one of the main meridians of the eye has a normal index (its focus is on the retina), and the other is myopic (focus is in front of the retina).Astigmatism in children is characterized by myopic refraction in the two principal meridians, but the tricks are located at different distances from the retina (in front of her).

farsightedness astigmatism in children (hyperopic astigmatism in children) also is of two types - simple and complex.Simple hyperopic astigmatism is one of the main meridians of the refraction of the eye is normal, and the other farsighted (focus is behind the retina).Difficult hyperopic astigmatism in children is characterized by far-sighted refraction in the two principal meridians, but the tricks are located at different distances from the retina (for her).

Mixed astigmatism - a combination of myopic astigmatism in one main meridian on the other long-sighted.Astigmatism can be as in one eye, and both.



In most cases, astigmatism in children is hereditary.A feature of astigmatism in children is that it can manifest itself as soon Field of birth, and during the growth and development of the child.At present it is established that leads to the development of astigmatism in a school or adolescence.However, astigmatism and at this age is hereditary, since many children can identify relatives with astigmatism.

innate feature of the structure of the cornea's not considered a disease - it's just a feature of the structure of the eye tissue, which subsequently require correction.


How is astigmatism in children

Astigmatism in children under one year are very common.Astigmatism in the newborn can match 1.0 - 2.0 D (diopter).Later astigmatism in infants and reduced astigmatism in one year old child can already be 0.5 - 0.75 D. The small degree of astigmatism may persist in human life, nor did he notice any abnormalities in vision.This is called physiological astigmatism.

Sometimes children astigmatism can not only decrease, and progress, and the process can begin at any age - it is associated with the peculiarities of the physiological development of the child.And as is often the astigmatism in children up to a year at the same time developing nearsightedness, farsightedness, or squint, vision problems increase.Astigmatism can occur in adolescents - a risk factor contributing to its development, is hormonal changes.

astigmatism If the child is not treated, over time, become familiar visual impairment and affect the state of the tissues of the body as a whole.

The result is a condition called amblyopia.Amblyopia (also called lazy eye) - a decrease in vision that can not be corrected with glasses or surgery - it is difficult to treat.


Symptoms Symptoms of astigmatism in a child up to a year is hard to notice.A reference point for parents can serve as a family astigmatism and the emergence of more or less pronounced strabismus in children - children up to one year astigmatism often associated with strabismus.

attentive parents can observe the child of two - four years, he was badly distinguishes the individual items may not correctly identify their shape (round, oval, square, rectangular, triangular), while the other children this age can easily cope with this task.Attention is drawn to the fact that the child is not able to determine which object is on, and a closer.

children after five or six years may already have certain complaints.They say that they see all the vague, fuzzy, distorted.But even in this age of the child does not understand what he sees not how everything, so in most cases complaints vision does not show.Poor vision makes such a child to tilt his head, squints to see better.Because of the tension in his eyes can occur headaches and eye fatigue.The eyes are often irritated and turn red.

Cheerleaders parents have frequent headaches, dizziness, especially when visual load.Especially all these symptoms intensified after the child goes to school, where the visual load will increase manifold.The child is difficult to focus the mind on the printed text.Because of headaches and blurred vision child will fall behind in school and, as a consequence, in the neuropsychological development.

At any age against the backdrop of uncorrected astigmatism can develop strabismus.



Treatment of astigmatism in children depends on the type, severity and age of the child.The main objective of treatment is to correct vision with glasses or lenses - this will avoid the complications of astigmatism in the form of strabismus and amblyopia.Conservative treatment, stimulating all areas of the retina, have a positive impact on the eye.Vision for children becomes more acute, decreases the degree of distortion of the image, which can reduce power points, and sometimes even completely get rid of them.

Slight astigmatism up to 0.5 D is not complicated myopia, hyperopia farsightedness - than it is fraught? Hyperopia - than it is fraught? or strabismus usually does not require correction.But sometimes even that astigmatism can cause headaches in a child - in this case it is subject to correction.

Points for children with astigmatism are the most common method of correction.Used glasses with astigmatic (cylindrical and spherical) lens.The spherical component glasses needed to correct spherical refractive errors - nearsightedness or farsightedness.The cylindrical component of the points needed to properly refracted light beam and the focus going into a single point.Vision in astigmatic glasses becomes crisp and clear.

correction of astigmatism can be conducted by means of special toric contact lenses.Vision correction in this case is exactly the same as when using the points.

Today, in specialized stores you can buy toric contact lenses of different types, including day.Daily contact lenses today are considered most preferred for children, because it does not require any maintenance and can not serve as a source of infection.

If amblyopia astigmatism complicated, then it is much more difficult to treat.In this case, treatment is carried out strictly according to the individual plan.In accordance with the condition and the general state of the body of the child is assigned the complex treatment includes various methods of exposure.

Surgical Treatment of astigmatism Treatment of astigmatism - conservative or surgical? Treatment of astigmatism - conservative or surgical? children are usually not carried out due to the fact that the formation of organs of vision may continue until adulthood.


Exercises with astigmatism in children

eyes Gymnastics for children with astigmatism usually appointed doctor - the execution of certain movements is useful for different types of astigmatism.Examples of exercises for eyes with astigmatism:

  • look into the distance, take your finger in front of him at a distance of 30 cm from the eye and fix it look then translate view at some distant object;
  • eyes open "to write in the air numbers and letters;
  • much zazhmurivatsya and then relax;
  • closed his eyes, massage eyelids with your thumbs in a circular motion.

After a prescribed set of exercises you need to close your eyes and give them a rest.
