Expert Opinion

"At the moment, those undergoing the treatment are between 16 and 53. On average, after only 10 sessions, not only is there great improvement in vision but it is also maintained for at least two years."
Prof Donald Tan, Director Singapore Eye Research Institute and Deputy Director, Singapore National Eye Centre
"This treatment helps the brain to better understand the images the eyes are sending it, rather than altering the images the eyes receive by using corrective lenses or surgically altering the eye itself."
Dr Chan Wing Kwong, Senior Consultant and Head of Refractive Surgery Centre, Singapore National Eye Centre
"For example, select an item in your house that you cannot see clearly. After that, every five sessions, take a look at the object again and you will notice that your vision has become sharper. These are testimonials from patients who have experienced this."
Prof Donald Tan, Director Singapore Eye Research Institute and Deputy Director, Singapore National Eye Centre
"Vision is dependent on two things, how your eye receives the image and how your brain interprets the image. NeuroVision helps the brain to interpret sharper images."
Dr Chan Wing Kwong, Senior Consultant and Head of Refractive Surgery Centre, Singapore National Eye Centre
"Naturally we were quite skeptical about the whole thing, because traditionally, ophthalmologists thought that apart from glasses and surgery, other methods wouldn't work for myopia. But we tried it out, and it did work."

Causes Of Amblyopia

• Strabismus - Crossed / Wandering Eye
Strabimus
Strabismus denotes a condition where both eyes of a patient are not aligned and are not looking in the same direction. The two eyes may be turned in or out (horizontal squint) or up/down (vertical squint). If this condition newly affects an adult, double vision or diplopia would result. In a child, one of the images is 'suppressed' to avoid double vision ie, the brain learns to ignore images from one of the eyes. If this persists, the development of connections between that eye and the brain is adversely affected.


• Anisometropia - One eye being strongly near-sighted or far-sighted compared to the other eye
A large difference in spectacle power between the two eyes results in one eye perceiving much clearer vision than the other. Lazy eye is particularly likely to result if one eye is much more far sighted than the other, but can occur whenever the difference between the two eyes is large. As the image from one eye is constantly blurrer, the brain learns to suppress the image from that eye and eventually the nerve connections between eye and brain fail to develop normally.


• Meridional – One or both eyes having high astigmatism
Astigmatism of a high degree causes blurred vision for all distances. As this blurring occurs for both far and near, the child's brain fails to receive a clear image at any time and lazy eye results. Low degrees of astigmatism less than about 1.75D (175 degrees) generally do not cause amblyopia even if glasses are not worn. Higher degrees, if not corrected by spectacles or contact lenses, may cause amblyopia in one or both eyes.


• Cataract (less common) - Clouding of the natural lens of the eye
Any eye problem which blocks light and vision such as a cataract or cloudy cornea in a child is likely to cause lazy eye if severe enough. If this happens in both eyes, the two eyes could become equally amblyopic. Treatment in such cases includes surgery to correct the underlying abnormality such as cataract. If the patient is young enough, patching of the unaffected eye is then performed after surgery to force the child to use the lazy eye more.
