Retina diseases
Contents:
Description:
Retina – the thinnest and complex structure of an eye performing its svetovosprinimayushchy function. Therefore retina diseases always lead to decrease in sight.
Symptoms of Diseases of a retina:
Basic diseases of a retina:
* retina angiopatiya
* peeling of a retina
* retina dystrophy
* diabetic retinopathy
* rupture of a retina
* retina degeneration
* makulodistrofiya and macular degeneration
* retinitis
* azotemic retinitis
* retina tumor
* retinal apoplexy
Reasons of Diseases of a retina:
Pathological changes in a retina can be inflammatory, dystrophic, vascular and degenerative character. They can carry both the inborn, and acquired character.
Pathologies of a retina can arise at various general and general diseases — an idiopathic hypertensia, a diabetes mellitus, a disease of kidneys and adrenal glands, and also at eye injuries, craniocereberal injuries. Some infectious diseases (flu, etc.) can be complicated by retina diseases.
Treatment of Diseases of a retina:
Conservative treatment.
At the most initial stage, some of the listed above retina diseases, are treated by conservative methods — by means of medicines (injections of anti-inflammatory drugs, antibiotics, etc.). A main objective of conservative treatment is removal of an inflammation, but also it is effective at germination of vessels in a retina, at degenerative changes and hypostasis of a retina, accumulations of blood in a vitreous.
Laser coagulation of a retina.
Laser coagulation of a retina leads to sharp temperature increase that causes coagulation (coagulation) of fabric. Thanks to it operation takes place without blood. The laser has very high precision and is used for creation of unions between a retina and vascular obolochny eyes (i.e. strengthening of a retina).
This type of treatment is only and uncontested at changes on a retina of an eye, a "trellised" degeneration of a retina, dystrophy — "a trace of a snail", at vascular diseases of eyes, for example, the diabetic changes on a retina connected with a diabetes mellitus, fibrinferment of the central vein of a retina, an angiomatosis, an age makulodistrofiya, vascular pathology of veins (fibrinferments).
Peripheral preventive laser coagulation of a retina.
Peripheral preventive laser coagulation of a retina is a procedure of strengthening of a peripheral zone of a retina. Retina dystrophy often leads to gaps in these zones and to emergence of amotio of a retina which it is characteristic sharply reduces sight. PPLK allows to warn retina amotio. PPLK improves blood supply, increases blood-groove speed, improves food of the struck area of a retina, interferes with penetration of liquid under a retina and, as a result, to its flaking.
Viktrektomiya. The essence of this surgical method consists all vitreous of an eye or its any part and its replacement by special saline solution or artificial polymers at a distance. Need for performance of a vitrectomy often arises during operation for retina amotio.
