Far-sightedness in children - to identify and treat as soon as possible
farsightedness in children at birth there is always a but a physiological hyperopia, which is gradually taking place with age.Children often occurs and pathological hyperopia, which may be complicated by a decrease in visual acuity and strabismus.
congenital hyperopia children
Hyperopia - a violation of refraction (its refractive power) at which the refracted rays focus is behind the retina and the man sees all close objects clearly.
A newborn baby has a farsightedness of about three diopters (+ 3D), which is associated with a relatively short length of the anteroposterior axis of the eye.In the future, with the growth of the eyeball farsightedness decreases, the optical focus moves onto the retina, vision becomes normal or even goes into myopia.Normally, long-sightedness in children under one year and slowly decreases to a year should not exceed +2,5 D.
But this is not always, and sometimes far-sightedness, not only persists but increases, complicating amblyopia (off of bad seeing eye view) and strabismus Strabismus - how to find the cause? .Reasons for farsightedness in children are usually hereditary (inherited structural features of the eye) or congenital (due to some influences in utero) character.
How does farsightedness in children
main manifestation of hyperopia is blurred vision close objects.To better see something up close, the child has to strain your eyes.
Children's farsightedness is divided into three levels.Children farsightedness slight degree - up to + 2 D. Such violations are compensated by high contractility of the ciliary muscle and flexibility of the lens - while reducing the ciliary muscle lens becomes more convex, the focus falls on the refraction of the retina and the child sees well in the distance and near.But the constant eye strain leads to frequent headaches, eyestrain, neuroses and gaps in school.
moderate farsightedness in children - from +2 to +5 D;these children see well into the distance, but can not clearly see objects in the vicinity.Hyperopia high in children - above +5 D;reduced vision, children do not see both near and distant objects.
When farsightedness of medium and high degree of gradual decline in the function of cells of the visual cortex of the brain, as they have not been a clear image, and therefore, there is no incentive for the normal development of the cells.This leads to a decrease in visual acuity, and the development of amblyopia.
Amblyopia or "lazy eye" - a decrease in visual acuity associated with changes in the cerebral cortex and can not be corrected, then there is even reduced vision with glasses.Long flowing farsightedness may also lead to the development of a convergent concomitant strabismus concomitant strabismus - which determines the characteristics of the disease .
Quite often, children do not notice the impairment, therefore, are important preventive examinations ophthalmologist who identify and treat these children.
Treatment of hyperopia children
Treatment begins with correcting vision with the help of the lens, that is, with the selection of points for continuous wear for children of preschool age.Matched lenses less important than performance farsightedness identified in the child.Children of school age are assigned points for a short distance, and with a high degree of farsightedness - for continuous wear.
constant wearing of glasses relieves tension from the eyes, stimulates the nerve cells of the visual cortex of the brain, promotes the growth of the eyeball and reduction of farsightedness.
children with hyperopia Hyperopia - than it is fraught? also recommended several times a year to conduct courses of treatment hardware.It stimulates the eyesight, eyeball growth, prevents and treats amblyopia and strabismus.Hardware treatment of hyperopia Treatment of hyperopia - long-term and regular children includes a number of different techniques, including the game elements.Selection methods for hardware treatment, their duration and frequency of use determines the eye doctor.Hardware treatment should be prolonged and regular.When used properly, these techniques allow to save the child from wearing glasses.
After a teenager turns 18, the correction of hyperopia can be done surgically.With an average degree of farsightedness may be performed laser vision correction due to changes in the curvature of the cornea using a laser vaporization medium layers on its periphery.With a high degree of farsightedness held intraocular lens replacement surgery.
farsightedness in children should be identified and treated promptly, without waiting for complications.
