Hi,
From childhood onwards I have very less power (vision)& black ball also not moving on my left eye.but I have very good power in right eye ,I went two, three doctors they said this problem can not be solved. Get me the details.

I need more details and clarification. What do you mean you have "very less power"? Do you mean you have not so good vision in your left eye? This can be corrected with contacts, glasses or surgery. Also, what do you mean by black ball? Are you referring to Macular Degeneration? Is there a black spot in the center of your vision? What is your age, please? Do you currently wear glasses or contacts? Do you have your prescription handy?

You have what is known as amblyopia. This typically happens in one of two ways. One eye has a greater degree of refractive error (power) than the other (refractive amblyopia) or one eye turns in or out (strabismic amblyopia)...

In the case of refractive amblyopia. One eye is moderately far sighted (hyperopic) while the other is far more far-sighted. In order to see clearly, the eyes must focus (accomodate). This process is yolked, so the eyes focus the same degree. The brain will only focus enough to get the less far-sighted eye clear and thus a clear image will never be obtained on the retina (think of this as the film in the camera). Without a clear image, the occipital lobe of the brain never develops enough to distinguish fine detail.

With strabismic amblyopia, the eyes are turned either in or out. The dominant eye will then be trained straight ahead and the nondominant eye will be shut down by the brain, which vastly prefers using one eye only to double vision (remember, they aren't pointing in the same direction).

In either case, once a child reaches the age of 8, the brain "locks in." From this time on, the eye turn or the differnce in prescription can be corrected, but the brain development (or lack of) is permanent.

You only have one good eye, so remember to wear polycarbonate glasses or safety glasses whenever there is possibility of injury. I've seen far too many lives ruined by an accident that takes out the good eye.

Cheers

Thank you for all the information, but is it wise to diagnose a "patient" without ever examining them?
