Approximately 2-4% of children with strabismus
If beginning in early childhood can lead to reduced vision in the affected eye
There are many causes of squint, some of which are not fully understood

What is strabismus?
Strabismus is a squint. The eyes are misaligned and look in another direction. One eye may look straight proceed, while the other eye turns inward, outward, upward or downward. Eyes turned to straighten the eyes straight time and are subject to change.
Strabismus is a common condition in children. Approximately 2-4% of children with strabismus. It can also occur later in life. It occurs equally in men and women. Strabismus may run in families.
How does the eye work together?
With normal vision, both eyes aim at the same spot. Brain then combines the two images into three-dimensional images. The three-dimensional image gives us depth perception.
When an eye turns, two very different pictures are sent to the brain. In a young child, the brain learns to ignore the image from parallel and look at pictures of eyes straight or better to see. Child then loses depth perception. Adults who develop strabismus often have double vision because the brain is not able to ignore the picture of the changes in the eye.
Generate good vision during childhood when both eyes are normal alignment and focus. Can cause reduced vision, or amblyopia is Strabismus, eye squinting. Brain will recognize the shadow of the strong eye and ignore the image from the weaker or amblyopic eye.
Amblyopia can be treated by patching the eye “beautiful” to strengthen and improve the weaker eye sight. The Amblyopia can be permanent if treatment is delayed. As a rule, been considered earlier amblyopia, better vision ended.
What causes strabismus?
The exact cause of strabismus all squinting or not fully understood. Six eye muscles that control eye movement are attached to the outside of each eye. In each eye, two muscles move the eye horizontally. Four muscles move it up, down or tilted. Upang line up and focus both eyes on a single target, all of the muscles in each eye must be balanced and working together – the muscles in both eyes must be coordinated.
Brain controls the eye muscles. The Strabismus is quite common in children with diseases that affect the brain, such as cerebral palsy, Down syndrome, hydrocephalus and braintumours. Cataract and other causes of poor vision can also cause strabismus.
How is strabismus diagnosed?
The main symptom of strabismus is an eye that does not appear to tune in each eye. Sometimes children will close one eye in bright sunlight or tilt their heads to use their eyes. The Strabismus can be diagnosed through an eye exam.
It is recommended that all newborns undergo an eye examination by theirpaediatrician, and a re-evaluation of four to six months. Children should have their vision checked by theirpaediatrician, family doctor, optometrist, orthoptist ophthalmologist, (eye specialist), or screening of pre-school, on or before their fourth birthday. If there is a family history of strabismus or amblyopia, ophthalmologist should assess their vision even earlier.
Baby eyes often seem to cross. Children are often the nose, the wide flat and folds of skin at the inner eyelid eyes look crossed. It may be necessary to enhance the appearance as the child grows. A child can not cope with correct strabismus. An eye doctor can distinguish between true and false squint.
What kind of cross-eyed?
Esotropia, where the eye turns inward, the most common type of squint in infants. In most cases, early surgery to realign the eyes. During surgery for esotropia, eye muscle tension, in one or both eyes, suits.
A common form of acquired esotropia that occurs in farsighted children a little older the Accommodative esotropia. As a child, he can direct the eye to adjust to the far sightedness, but can cause the eyes to cross these efforts focus (accommodation). Glasses can reduce the effort to focus and align the eyes. Very rarely needed bifocal glasses for close work. Eye drops or special lens called prisms can also be used in the management of this disorder.
Exotropia, or behind the eyes of outsiders, a common type of strabismus. Often occurs when a child is committed to the distant objects. Exotropia may occur only from time to time, especially when a child is daydreaming, ill or tired. Parents often notice that the child is closing one eye in bright sunlight. Although glasses, exercises or prisms may reduce or help control the rotating eye out, some children, surgery is often required.
How is strabismus treated?
Treatment for strabismus aims to preserve or restore vision, straighten the eyes and develop binocular (two eyes) vision. After examination of the eye, including the application of students who flaunt eye drops, eye doctor will recommend the appropriate treatment. In some cases, the glasses may be prescribed. Covering or patching the strong eye to improve amblyopia is often necessary. Other treatment may include surgery to correct the unbalanced eye muscles or, very rarely, to remove a cataract.
Eyeball is never removed from the socket during any type of strabismus surgery. Ophthalmologist makes a small incision in the tissue covering the eye to reach the eye muscles. How many muscles are repositioned during surgery, depending on the direction has changed. It may be necessary to perform surgery on one or both eyes.
A generalanaestheticis usually required. Fast recovery time and usually return to normal activities within a few days. Sometimes more than one surgery may be necessary to straighten the eyes. After surgery, glasses or prisms may still be necessary.
As with any surgery, eye muscle surgery has some risks. These include infection, bleeding, scarring on the white of the eye and other rare complications that can lead to vision loss. Safe and effective treatment for strabismus Strabismus surgery. It does not, however, a substitute for glasses or occlusion therapy.
An alternative to surgery
Botox (TM), a drug known to be used to reduce facial wrinkles by relaxing facial muscles, is an alternative to eye muscle surgery for some forms of strabismus. Injections of drugs into the muscles while the eye muscles, so the muscles devoted to tighten and straighten the eye. Although the effects of the drug will disappear after a few weeks, the misalignment may in some cases permanently corrected
