What is it?
Bynocs AmblyGo is a uniquely designed cloud based software for management of Amblyopia (or lazy eye) based on the dichoptic principle.
Dichoptic training is a visual training process involving the presentation of different stimuli to each eye. In order to achieve the desired results, the summation of both stimuli is required. For instance, the object of the game may be presented to the amblyopic eye and the background to the other eye.
By using Bynocs AmblyGo, the user is forcing their weaker (ambylopic/ lazy) eye to be used, over time achieving a better level of vision in their weaker eye and and improvement in binocular or 3D vision.
The current concept is that Amblyopia is a binocular dysfunction, and it is caused by suppression by the ocular dominance columns of the dominant eye over the non-dominant eye at the level of the cerebral cortex (brain). Dichoptic therapy is emerging as a very effective tool in the management of Amblyopia. Here, contrast-adjusted images are presented to the 2 eyes, with the dominant eye getting an image of lesser contrast than the non-dominant eye. For possibly the first time ever, during the therapy, the brain is receiving an equal image from the two eyes. This encourages the brain to use both eyes at the same time.
This contrast differentiation removes the interocular suppression in the ocular dominance columns and results in a visual gain of the amblyopic eye. Bynocs vision therapy software for lazy eye now offers treatment for Amblyopia in the form of games. The patient plays games on a patented software with both the eyes open and wearing special anaglyph glasses (that have different colour lenses).
Amblyopia can develop in childhood and may continue to persist in adulthood. Symptoms include:
- Blurred or double vision
- Uncoordinated eye movements
- Squinting eyes/ crossed eyes
- Poor depth perception
- Closing one eye to see better
What causes it?
Refractive Errors and Anisometropia
Refractive error in an eye simply means that the eye cannot focus correctly, leading to near-sightedness, far-sightedness, or astigmatism and requires glasses or contact lenses to improve the focus. In addition, uncorrected refractive errors can strain the eye muscles, which have to work harder to achieve a better focus.
In some cases, both eyes have different magnitudes of refractive errors known medically as ‘Anisometropia.’ One of the eyes may have a significantly poorer vision than the other. When this happens in one of the eyes, the brain tends to rely more on sharp impulses from the normal eye and subsequently ignores the weaker eye, resulting in it becoming lazy or amblyopic.
Muscle Imbalance or Strabismus
Our eyes have a set of muscles that control eye movements. A weakness in any eye muscle will lead to abnormalities in the movement, such as turning inwards or outwards or having uncoordinated movements. The affected eye thus becomes ‘lazy,’ and the brain learns to ignore the poor visual stimulus from the lazy eye.
A cataract is a condition where the natural lens of the eye becomes cloudy and reduces the quality of the vision in that eye and may lead to amblyopia in the affected eye. Cataracts can occur in infancy as well as develop in later life.
How is it treated
Dichoptic Eye Treatments
Treatment for the eyes using dichoptic technology is an emerging and highly effective approach for correcting lazy eyes and improving vision. Dichoptic eye treatments work by offering simultaneous and separate visual stimuli to both eyes. In simpler terms, depending on the impairment, both eyes are presented with different stimuli simultaneously, which helps enhance the contrast difference perceived by both eyes. This can help achieve a balance between the normal eye and the lazy eye.
Bynocs AmblyGo includes various games for better engagement, and it is recommended to play these games for 30-40 minutes and at least 5 times a week. Usually, the initial improvement is seen after 2 weeks, and a good result can be expected in 6-8 weeks in appropriately selected cases.
Advantages of Bynocs AmblyGo:
- Good compliance as children love to play games
- 90% success rate
- No recurrence
- Being a binocular treatment it develops stereopsis or 3D vision
- No incidence of Diplopia (double vision)
- Successful in managing Adult amblyopia (previously no solution)
