What is hypermetropia


Amblyopia is a developmental visual impairment that is the most common reason for reduced visual acuity in one eye, and more rarely in both eyes, in early childhood. There are no organic causes - the eye is therefore anatomically healthy. Since amblyopia can lead to permanent and significant impairment of vision without being recognized, an early diagnosis in childhood is particularly important. The eyesight of small children should be checked at an early stage as part of the preventive medical check-ups.

The causes of vision loss are different. Amblyopia is a typical consequence of strabismus in approx. 25% of cases. The child's brain is able to suppress the visual impression of the cross-eyed eye so that only the better eye is used. The visual acuity of the neglected eye is reduced as a result. Impaired vision caused by strabismus and the suppression or suppression of the visual impression is also referred to as suppression amblyopia.

In about 50% of the cases, refractive errors (ametropia or refractive errors) are responsible for the development of amblyopia, which is then called refraction amblyopia. A distinction is made between different forms of ametropia - this includes the Myopia (Myopia) that Hyperopia (Farsightedness or clarity) and the astigmatism (Astigmatism or astigmatism). The highest risk of developing impaired vision is the presence of astigmatism, followed by hyperopia. Myopia is rarely a cause. In practice, mixed forms of amblyopia are usually represented, which are caused, for example, by strabismus and additional refractive errors. For this reason, thorough examination is very important for optimal treatment.
