Causes, symptoms, methods of curing congenital and other types of cataract in children
One of the most frequent eye diseases is cataract. In general, it is diagnosed in adults and elderly people, but often it can be found in children.
The frequency of spreading in newborns is 5 people per 100 thousand, in older children 3-4 cases per 10 thousand people.
Cataract is an eye disease, at which there is a turbidity of the substance of the lens with a partial or complete loss of visual acuity. The turbidity can be either total or incomplete.
According to the International Classification of Diseases 10, the revision of nosology is encrypted as H25 – H28. But the congenital cataract in children according to the ICD-10 has the code Q12.
The lens is a biconvex lens, it refracts the sun’s rays passing through it, and focuses them on the retina.
Irritation from the retina is transmitted along the optic nerve to the information processing zones in the brain.
With cataracts due to opacity, the refraction of sunlight is disturbed, the image on the retina becomes blurred.
Usually, I can not find the exact cause of cataracts, but there are factors that can predispose to its development.
The following reasons can be attributed to them:
Thus, it can be considered that the disease is linked to some genes and there is a high probability of cataract in the offspring.
If the operation was performed on both eyes, To achieve focusing of the image in the retina area, use multifocal glasses.
These glasses have thick glasses and contribute to the vision in the distance, near and at an average distance. Bifocals are also used, but unlike previous ones, they provide vision either in the distance or in the vicinity.
If the cataract was removed only on one eye, it is advisable to use contact lenses. Since the eyes of children are constantly growing, then the lens after a while needs to be changed and selected by others in size.
Parents should closely monitor the use of contact lenses by children, since there is a high risk of infection.
The ideal option for restoring vision is an operation for the implantation of an artificial intraocular lens.
In this case, the eye begins to function fully, which manifests itself in the form of focusing the image as if in the distance, so close.
Operation of implantation of intraocular lens It is also carried out simultaneously and can be combined with the removal of cataracts. Combination is possible in children older than 5-6 years and in adults.
