AMBLYOPIA EYE CAUSES AND ITS TREATMENT

 

Amblyopia is a disease characterized by a disorder of the visual analysers that threatens to reduce visual acuity without visible changes in the eyeball.

At the same time, the visual process is disrupted - the eyes see completely different pictures, which the brain cannot correlate, as a result, the more "weak" is suppressed by the strong and almost stops working. The giandliverconsultants provide the best gastrointestinal consultants in USA.

People with amblyopia cannot compare in a single image seen with two eyes, which distorts the depth, volume, sequence of depicted objects. vision correction in the case of amblyopia using only optical and contact lenses is not possible.

Causes of amblyopia of the eye

strabismus, due to deviating from the natural position of the eyes begins to see worse. But the lazy eye syndrome can provoke strabismus, because too low vision makes it impossible to merge the picture;

hereditary refractive error (refraction of light rays in the optical system), transmitted from parents. This probability is 50%;

violation of the contraction and relaxation of the eye muscle, the elasticity of the lens and the connection around it;

congenital anomalies of the cornea or lens (opacity, congenital cataract);

Types of amblyopia

Based on the reasons that provoked the development of this pathology, there are primary forms of optical disorders and secondary - when the successful treatment of one problem provoked a drop in severity.

Primary forms of amblyopia

Dysbinocular

Occurs against strabismus. The patient has no binocular vision. This means that the eyes see differently, and the brain cannot put together and analyze the picture.

Refractive

the causes are hidden in the untimely detection and correction of ametropia in childhood (changes in the refractive power of the human eye), which stop the development of the visual system. Manifested in the absence of clear focus on the retina.

Symptoms:

·         lack of clarity when looking into the distance / near;

·         inability to clearly distinguish contrasts and shades of colors;

·         inability to focus on a bright object; detailed study of the object is possible only with one eye (the second often has to be closed);

·         permanent headaches and fatigue of the visual system; strabismus;

·         ptosis (drooping eyelids);

Diagnosis

Detailed analysis of complaints of visual impairment and their prescription;

analysis of the patient's lifestyle, the presence of injuries, optical disorders, hereditary predisposition.

verification using well-known tables (visometry).

Refraction, refractive power of the cornea is also studied. Ultrasound examination of the fundus and about 5-6 more procedures using special equipment.

Treatment

·        The giandliverconsultants provide the best liver consultants in USA.

  wearing lenses or glasses, a special bandage (valve) to train the "lazy eye";

·         hardware stimulation (complex of medical devices);

·         Ambliocor device;

·         change the state of a healthy eye by medication;

·         laser correction;

surgical removal of strabismus and drooping eyelids.

Timely non-intervention in the development of the disease has unpleasant complications and consequences, which are manifested in an even greater weakening of vision, up to its complete loss in the weak eye, the development of strabismus.

 

Symptoms:

·         acuity and visual concentration;

·         limited field of view;

·         corneal sensitivity;

Main reasons:

cataract (congenital or developed);

corneal opacity, ptosis (anomaly of the century).

Other risk factors include leukemia, floating vitreous opacities, circulatory and lens disorders.

Characteristic signs of the disease - remained low visual acuity after the removal of turbidity in the absence of noticeable anatomical changes in the fundus.
