The patient with an amblyopia
Amblyopia reasons:
The amblyopia most often develops as a result of squint, an inborn cataract, opacification of a cornea, a ptosis of an upper eyelid, a difference in sight between eyes and nekorrigiruyemy short-sightedness, far-sightedness or an astigmatism. The amblyopia can be various degree of manifestation - from insignificant decrease in sight to photoperception.
Patients with an amblyopia have no solid vision - ability of a brain to correctly compare two images of both eyes in a single whole. This ability is necessary for an opportunity to estimate depth, i.e. what subject under review is for what. At an amblyopia it is impossible.
Treatment of the Amblyopia:
Treatment begins with correction of the reason which caused an amblyopia. If this disturbance of a refraction, then the corresponding points, contact lenses and even laser correction of sight appoint. Squint will demand special treatment, and at its not success and surgical treatment. The inborn cataract and omission (in the medical ptosis language) an upper eyelid are treated surgically. After elimination of the reason of an amblyopia start its direct treatment. The doctor can appoint sticking up of an eye with the best sight that will force the child to use a sore eye and by that to develop his sight. With the same purpose can appoint a long instillation of drops of atropine in the best eye. Besides, ways of stimulation of an ambliopichny eye by light flashes - so-called photostimulation are developed. Irrespective of the fact which treatment is applied, the most important is timeliness of its beginning, till the moment until the brain of the child learned to suppress or ignore an ambliopichny ("lazy") eye forever.
