Significance of an eye muscle and the basic indications to carrying out of an eye muscle surgery

Added: 01/19/2006

For the last two dozen years or so, studies have shown that nearly 40% of the population of Europe and America is suffering from poor eye sight. The cause? Increased use of computers, low light, and too much work that creates eye strain. Vision has been shown to be reduced in teenagers, older people and businessmen. When this strain is prolonged, the risk of serious eye diseases dictate that eye muscle surgery is required. However, in many cases the problem of deterioration of vision is connected to atrophy or weakening of an eye muscle. Therefore, an eye muscle surgery is effective and necessary means for reduction of vision.

The eye is one of the most complex organs of human body, and one of the organs we depend on the most This organ works as a set of several complex systems. Quality of vision depends not only on a transparency and plasticity of crystalline lens, conductivity and normal functioning of an optic nerve and structure of retina.

One of the major components of vision organs is the eye muscles. With the help of eye muscles the movement of an eyeball is carried out. Muscles can compress and weaken an eyeball that allows adjusting curvature of crystalline lens and sharpness of image. The eye muscle is attached to an aluminous coating of an eye which refers to sclera.

In some cases the eye muscle can be able of chronic tone. As a result there is a squint. At a squint the eye muscle is constantly in a pressure. The squint is characterized by significant infringement corner of vision, however at the long squint irreversible pathological changes of an eyeball form can begin. In this case doctors-ophthalmologists recommend leading eye muscle surgery. At eye muscle surgery surgeons make loosening and weaking procedures as a result of which the form of an eyeball and normal corner of vision is restored.

However, in some cases there is a problem of an eye muscle weakening. At weakening or dystrophies of an eye muscle some serious enough pathology can arise. To number pathologies of vision organ arising as a result weakening of function and tone of an eye muscle it is possible to attribute: ptosis of blepharon, short-sightedness, far-sightedness, infringement of accommodation, astigmatism.

These pathologies can be corrected with the help of special system of exercises, allowing strengthening of the eye muscles. However, in some cases, doctors recommend carrying out eye muscle surgery. If an eye muscle surgery is aimed at strengthening and compression of an eye muscle, during operation notch of muscle and its shortening is carried out. As a result of similar tightening and strengthening procedures the eye muscle restores ability to reduction.

The problem of vision correction with the help of eye muscle surgery is enough actual. In the opinion of some ophthalmologists, in case of serious pathological changes; the artificial function of eye muscles can be accomplished with special artificial eye muscles. The group of the American researchers of state New Mexico is engaged in creation of an artificial muscle. The muscle is sewn in sclera and at reduction promotes lengthening of an eyeball.

In this case, the image gets precisely on the retina of an eye that allows correcting of far-sightedness. The relaxation of muscle results in boomerang effect. Reduction of an artificial muscle copes with the external device which on the size corresponds to size of standard hearing apparatus. At inclusion this device generates the magnetic field which influences an eye muscle, promoting its reduction.

However in most cases, easing contractibility abilities of an eye muscle can be corrected with the help of a special program of corrective exercises. Therefore, in order to avoid eye muscle surgery, people suffering from a dysfunction of the eye muscle have to be actively engaged on the regular basis in the complex series of exercises for the correction of vision. It's not easy, but not impossible. It just takes hard work and focus.
