Belmo (synonym – leikoma) – the process of corneal clouding caused by its cicatricial changes.
- Keratitis (viral, tuberculosis, etc.);
- Injuries (injuries, chemical and thermal burns);
- Eye surgery;
- Congenital corneal opacities.
The belt may occupy part or all of the cornea. The influence of the catcher on the sight depends mainly on its location, size and intensity. Thus, when a cloud is formed as a result of improper refraction of light rays, a distorted or indistinct image of objects appears. The corneal spot at its central location leads to a significant decrease in visual acuity.
Actually, an eyesore, especially as a result of an alkali burn, may be accompanied by a sharp decrease in visual acuity, up to the preservation of only light perception.
When located around the periphery, the cataract affects the visual acuity less than when localized in the center of the cornea against the pupil.
The surface of the leprechaun, formed after the ulcerative processes of the cornea or mechanical damage, is uneven, the cornea in the area of the leprechaun is often thinned.
When an ulcer or a penetrating wound of the cornea as a result of subsequent scarring, the cornea is welded to the iris, which leads to the deformation of the pupil, the development of a secondary glaucoma .
Minor corneal opacities (clouds) do not require treatment.
Treatment of corneal spots and the actual cataract is only operative. Corneal plasty is used, which allows, in a significant number of cases, to restore vision even with dense extensive opacities.
Drug treatment is carried out only with residual inflammatory processes in the cornea. The choice of drugs depends on the cause of the disease; they prescribe, for example, anti-tuberculosis, antiviral drugs, which in some cases leads to some enlightenment of the leucorrhoea.
The prognosis for surgical treatment is favorable. In case of thorny spot after severe chemical and thermal burns, due to the development of possible complications, the prognosis is doubtful.
