Myopia in children of mild, moderate to severe severity; code on ICD-10, symptoms and types of disease
Myopia in children, better known as myopia (ICD-10 code of disease; H52.1); one of the most common disturbances in the work of the organs of sight.
Its main feature is the deterioration in the ability to see objects located far away, connected with a refractive defect.
Depending on the time of occurrence, the nature of the course of the disease, the degree of disruption of the function, several of its varieties are identified.
Congenital and acquired
By the time of origin, congenital and acquired myopia. The first is formed in the process of intrauterine development. Depending on anatomical reasons, it is divided into refractive and axial.
In the first case, the normal size of the eye remains, but the refractive power of its internal environment is excessively increased. In the second, the anteroposterior axis of the eye increases, while maintaining a normal refractive index.
The main causes of congenital form are called prematurity and the pathology of intrauterine development, caused by a mother-borne disease.
For congenital myopia, children are also characterized by a high degree and concomitant diseases of the visual apparatus, for example, changes in the fundus associated with abnormal development of the optic nerve and the macular area.
