Hyperopia (farsightedness) is a physiological type of refraction when it comes to a young child. This type of refraction is caused by the short anterior-posterior axis of the eyeball, a small corneal diameter, and a shallow anterior chamber.
Changes in one or more of these parameters cause refractive disorder. For example, excessive growth of the eyeball in the anterior-posterior direction leads to the development of myopic refraction.
Amblyopia is a functional decrease in visual acuity caused by disuse of the eye during visual development. Blindness may develop in the affected eye if amblyopia is not diagnosed and treated before age 8. Diagnosis is based on detecting a difference in visual acuity between the two eyes. Treatment for amblyopia in children depends on the cause.
One third of eye patients in the West are children, and worldwide there are about 1.5 million children with severe visual impairment and complete blindness, many of whom suffer from genetic diseases.
Blunt trauma or contusion is accompanied by damage to various parts of the eyeball. In mild cases, damage to the epithelium can be observed - corneal erosion or damage to the epithelium and Bowman's capsule.
In terms of severity, eye contusion ranks second after penetrating wounds. Contusions of the visual organ are quite diverse in their clinical picture - from minor hemorrhages under the conjunctiva of the eyelids to crushing of the eyeball and surrounding tissues.
Fragments containing copper, when oxidized, lead to the deposition of copper salts in the tissues of the eye - chalcose. In the epithelium and stroma of the cornea, deposits of tiny grains of blue, golden-blue or green color are observed.
Siderosis of the eye is nothing more than the deposition of iron salts in the tissues of the eye. With siderosis, all tissues of the eye are saturated with iron salts - the stroma of the cornea, the deposition of brown pigment in the form of dust on the endothelium of the cornea from the side of the anterior chamber, which creates its brown opalescence.
To detect fragments, the following conditions are necessary: transparency of the surrounding medium; location of fragments in an area accessible for clinical examination.
