What causes Lazy eye ( Amblyopia )  ?

In order to understand how vision works, imagine the visual system as a digital

camera.  The camera has a lens and a processing center, which corresponds to

the eye and the brain.  Things seen through the lens (the eye) become images

and are transferred to the processing center (the brain).  The human eyes are like

two camera lenses placed side by side.  The images they transfer to the brain are

different, and therefore need to be analyzed and integrated in the processing center

to give a sharp, three-dimensional vision.  The development of the visual system

is continuing until the age of about seven.  In a child with normal vision, images

from two eyes fuse into a 3-D picture in the brain.  With an amblyopic eye, the

image it transfers to the brain is blurry and unclear, and cannot be fused with that

of the other eye. The brain gives up on the blurred image, and the visual cortex of

this eye no longer develops, hence causing amblyopia.

 

The “Kinetic Prism Amblyopia Training Method” stimulates the brain for refusion

of the images from two eyes; hence cause the re-development of the visual cortex. 

The effect is visible within six treatment sessions.  The most effective period of

treatment for Amblyopia is prior to adolescence. Therefore, it is best to begin

treatment before the age of seven, or at the latest, before the age of twelve.

 

Principle behind the Newest Treatment for Amblyopia

In the past, parents are often troubled if their children are found to be amblyopic. 

This is because amblyopia can not be cured by neither medications, eye drops, nor

surgery.  Children will have to wear an eye-patch over the good eye for a period

between over half a year to over years.  And if both eyes are amblyopic, each eye

take turns in wearing the patch.  But because the eye-patch is very uncomfortable,

and children feel embarrassed wearing it to school, the cure-rate of this treatment

is not high.

 

The newest treatment for amblyopia is the “Kinetic Prism Amblyopia Training

Method”.  It is especially effective in training amblyopia caused by high astig-

matism.  It utilizes kinetic prisms to alter the perceptions of space and distance in

the visual center of the brain.  With this method, every 20 seconds, the stimulation

causes binocular image fusion in the brain and hence reinforces and accelerates

visual development in the child.  The prisms also cause divergence of the eyeballs,

and the outward-pulling forces of the optic-nerve disks are relaxed.  Since the

tensions on the optic nerve are removed, subjective vision becomes clearer and

sharper.

 

 

No patching necessary and effective within six months

Unlike the traditional treatment which takes months of patching and boring tracing

on black and white strips (CAM), the“Kinetic Prism Amblyopia Training Method”

 is effective in improving the eyesight of all types of amblyopia, especially those

caused by high astigmatism.  The training session is two hours, and two to three

training sessions are necessary per week.  The training is not boring because it can

be done at the same time as watching TV or using the computer.  Within two weeks,

 those who are suitable for the training will show a two-line improvement on the eye

chart or even improve to 20/20 in their corrective vision.  Corrective glasses of the

right power should be worn from this time and the training can be done at home reg-

ularly to maintain the vision.  Those who do not show improvement of at least two

lines on the eye chart after the two weeks are suggested to use both the “Kinetic

Prism Amblyopia Training Method” and the traditional patching method together to

improve the chance of success. From clinical observations of the past 5 years, 70%

of the cases with the new treatment had 20/20 corrective vision after six months, and

15% showed, at least, a two-line improvement.  Clearly, the “Kinetic Prism Ambly-

opia Training Method”is faster and more effective in amblyopia treatment then others.

 

FAQ for Amblyopia Treatment

QDoes the“Kinetic Prism Amblyopia Training Method” involve surgery or medications?

ANot at all!  This new method only requires the wearing of the training device during the

      use of televisions or computers.

 

QIs the “Kinetic Prism Amblyopia Training Method” dangerous or pose any side effect?

AThis is a non-invasive, optical method, and therefore it poses no side effects.  It has been

      used extensively in the treatment of myopia and amblyopia, and no discomfort or side

      effect has been reported.

 

QWho is eligible for this “Kinetic Prism Amblyopia Training Method”?

AThose under the age of 12 and are diagnosed as being amblyopic are eligible.  Detecting

      the condition in early childhood increases the chance of successful treatment.

 

QHow does the “Kinetic Prism Amblyopia Training Method” begin?

A 1. The treatment should begin with a thorough diagnosis of the corrective vision and

           refractive error.

2. The training session begins by the wearing of the training device, with the addition

    of corrective lens clip or the patient’s own corrective glasses, during use of the

    television or computer.  Each training session is 1 ~ 2 hours, and 2 ~ 3 training   

    sessions are necessary per week.  The effect is visible    within two weeks of training.

 

Q What is to expect after two weeks?

A After six training sessions (two weeks), those who are suitable for the training will show

       a two-line improvement on the eye chart or even improve to 20/20 in their corrective

       vision. 70% of the clinical cases had 20/20 corrective vision         after two weeks, and

       15% showed a two-line improvement.  But it is necessary to continue the training for at

       least 6 months for the result to stabilize.

 

QIs the result of the “Kinetic Prism Amblyopia Training Method” permanent?

AThose with improvement after two weeks should continue      the training sessions 2 ~ 3

      times a week to maintain the      result.  Within four to six months, the result should be

      stable.  Those who do not show improvement of at least two lines on the eye chart after

      the two weeks are suggested to use both the “Kinetic Prism Amblyopia Training Method

      ”and the traditional patching method together to improve the chance of success.
