Hypermetropia (farsightedness) is a physiological kind of refraction when it comes to a young child. This type of refraction is due to the short anterior-posterior axis of the eyeball, the small diameter of the cornea and the shallow anterior chamber.
Changes in one or more of these parameters cause a refractive disorder. For example, excessive growth of the eyeball in the antero-posterior direction leads to the occurrence of myopic refraction.
Amblyopia is a functional reduction in visual acuity caused by the non-use of the eye during visual development. In the affected eye, blindness may develop if amblyopia is not diagnosed and treated prior to the age of 8 years. The diagnosis is based on finding the difference in visual acuity between the two eyes. Treatment of amblyopia in children depends on the cause.
One third of ophthalmic patients in the west are children, and there are around 1.5 million children with severe eye disorders and completely blind throughout the world, many of them suffering from genetically determined diseases.
Blunt trauma or concussion 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 the Bowman capsule.
By severity, eye contusion is second only to perforating wounds. Contusions of the organ of vision in its clinical picture are very diverse - from minor hemorrhages under the conjunctiva of the eyelids to crushing the eyeball and surrounding tissues.
The fragments containing in copper, oxidizing, lead to the deposition of copper salts in the tissues of the eye - chalcosis. In the epithelium and stroma of the cornea, deposits of the smallest grains of blue, golden-blue or green are observed.
Siderosis of the eye - is nothing like the deposition of iron salts in the tissues of the eye. With siderosis, all the tissues of the eye are impregnated with iron salts - corneal stroma, deposition of brown pigment in the form of dust on the endothelium of the cornea from the anterior chamber, which creates its brown opalescence.
To detect fragments, the following conditions are necessary: transparency of the environment in the immediate environment; Detection of fragments in a zone accessible for clinical examination.
