Amblyopia is understood to mean a decrease in visual acuity, which cannot be corrected with ordinary glasses, contact lenses. In this case, one eye falls out of the process of vision. From this, such a disease is also called “lazy eye syndrome." According to American researchers, low vision, which cannot be corrected, is on a par with cataract and glaucoma in frequency of occurrence. Change in visual acuity is reversible.
Causes of the disease
Most often arises as a result of strabismus. In this case, an eye with an axis deviation is not involved in the perception of objects. Amblyopia also occurs as a result of a high degree of myopia, hyperopia, or astigmatism. With an inadequate correction of these pathologies of vision, lazy eye syndrome also occurs.
Doctors also highlight the so-called hysterical amblyopia. It arises as a result of psychoses, nervous shocks.
Symptoms of Amblyopia
A typical sign of lazy eye syndrome is a decrease in vision of one or both eyes. Patients also cannot correctly assess the distance to the object.
Children cannot accurately assess how low their vision is. Therefore, the doctor thinks about the presence of a lazy eye syndrome whenever diagnosed with skolgazie, nystagmus. Sometimes children cannot navigate in an unfamiliar place, their adaptation to a dark place is disturbed.
In adults, signs of amblyopia can occur after severe nervous shocks. Most often this happens suddenly. Such visual acuity disorder can last from several hours to several months. The degree of vision loss can also vary - from almost imperceptible to almost complete, when only light perception is preserved.
Disease treatment
The outcome of amblyopia treatment depends on how early treatment is started. If the syndrome is diagnosed in children, then the preferred age for therapeutic measures is up to seven years.
In adults, in the presence of cataract, its removal is indicated. Surgical correction of ptosis and strabismus is performed. Vision correction is performed, which should be optimal.
To return the lazy eye to the visual process, the leading eye is glued and the retina is stimulated. Laser vision correction is also indicated.
Optical correction is used to provide a clear image on the retina. With weak myopia and farsightedness, a complete correction is made, with medium and high degrees of ametropia, the magnitude of the lenses is assigned by tolerance.
The result of treatment should be the restoration of the same visual acuity in both eyes.
