Amblyopia ("lazy eye") is a functional and reversible reduction of vision in the course of which one of the two eyes is almost not used (or not at all) in the vision process. The eyes register different images an d the brain fails to bring them together. This eventually suppresses functioning of one of the eyes.
Patients with amblyopia disorder have no binocular vision, i.e. the ability of the brain to correctly bring images of both eyes into one. This ability is essential for the estimation of the depth and the sequence of the objects within the field of vision, and the entity of perception. Amblyopia makes all this impossible.
Amblyopia: the causes
Amblyopia may develop due to a number of reasons. Strabismus is the most common cause. Amblyopia combined with strabismus is the result of the latter. While amblyopia in its turn may cause strabismus. This happens when one eye has such a low vision power (usually lower than 0.4-0.3 D) that combined imaging is not possible. The reason for low vision acuity lies in the changes which occur in the fundus of the eye, in the cornea, etc..
Amblyopia may affect people whose relatives suffered from strabismus and those who never had such problems.
It is essential to identify amblyopia as early as possible since with time this disorder progresses to the extent of complete suppression of the visual functions of the amblyopia affected eye.
It is important to bear in mind that it is hardly possible to identify amblyopia independently and that this disorder does not disappear with time. Quite often, a person accidentally closes one eye and realizes that the second eye is blind. That is why doctors recommend regular diagnostic checks at least once a year. Specialists point out that amblyopia may developed as a result of continuous absence of correction for refraction pathology, when a person does not wear glasses or contact lens and the eyes do not discern what a good vision and a bad vision are.
Treatment for amblyopia
Treatment for amblyopia may proceed in various directions: training of the amblyopic eye, true correction of ametrophy (optical defect), and removal of strobismus. The Excimer Eye Clinic conducts therapeutic treatment of amblyopia with Amblyocor – a unique apparatus which has been developed by leading specialists of the Institute of Brain. It is hard to believe that only a few years ago, ophthalmologists had no effective method to combat amblyopia (the “lazy eye”). Coordinated eye functioning could be restored then but not stereoscopic vision unfortunately (or not to a full extent).
Application of "Amblyocor"
Amblyocor operates on the basis of video-computerized autotraining. While the patient watches a film or a cartoon, the apparatus uses gauges to register data on the function of eyes simultaneously fixing an encephalogram of the brain. The image on the screen is retained only during "correct" vision and disappears as soon as it becomes unclear. In this way, the instrument stimulates the brain to subconsciously reduce the periods of uncontrolled vision. This method optimizes the performance of the neurons in the visual cortex, thus improving vision considerably.
