Lazy Eye

Background (cross eye issues)

Lazy Eye, (Amblyopia) is a dimness, or absence of vision in one eye. Lazy Eye actually causes a high percentage of vision loss in the under 40’s age.

The weakness or absence of vision perception may be a result of any of several conditions which can affect the eye during early development. Such as Strabismus, (the eyes are crossed inwards), Esotropia, (the eyes are turned outwards), or significant differences in refractive error of the eyes. For example, one may be short sighted, the other long sighted. Because the vision activity from an eye is not actively being used by the brain, the processes for “seeing” do not develop correctly. It is a self developing problem because the brain begins to use the image from one eye more than the other, and only hastens the demise of vision in the other.

The brain cells which process vision and color fail to develop for the weaker eye and vision and depth perception can be lost. The result can be part or even complete blindness in the neglected eye.

Treatment

Early diagnosis is important, because the longer it is left, the more difficult to overcome. If the cause is strabismus or some other alignment issue this should be addressed. In severe cases of strabismus, for example, the options used can range from surgery and or correction by lenses or glasses.

Occlusion, or patching of the stronger eye is also common, as are advanced eye exercises and therapies. A more recent alternative to patching is the use of drops to reduce the vision in the strong eye and force the other to function. Some believe that this type of treatment is may only successful up to about the age of 8. This is because the brain receptors which should be used by the weaker eye for vision, either fail to develop or actually “hook up” with the stronger eye. This leaves the weaker eye without the “tools” it needs to see! For this reason improving vision in a lazy eye after about the age of 8 is much more difficult.

However, improving vision in lazy eye of older people can be done. Partial occlusion (of the stronger eye), used in conjunction with extensive visual motor therapy has been effective. This would strongly suggest the use of active eye exercises and vision therapy should be part of treating amblyopia. In any event, if surgery etc is used to address causes, such as severe strabismus, eye exercises and visin therapy should not be neglected.

A good program of vision therapy to improve the individual function of the eye/s and their binocular synchronization may be highly successful in improving the brains “perception” of vision in a lazy eye.

You must do your own research and be confident in the choices you make. We believe eye exercises are highly beneficial for lazy eye.

The Eye Gym is great for lazy eye and cross eye.
