Amblyopia, colloquially known as “lazy eye”, is a neurodevelopmental disorder of the visual system which causes reduced vision in one or both eyes
It is usually a result of abnormal visual experiences during the developmental years.
With a prevalence of 2% -5%, it is among the leading causes of visual disability in children and in adults with residual disease.
Amblyopia may be due to:
- Anisometropia
- Strabismus
- Stimulation deprivation
Amblyopia has traditionally been considered as a mono ocular disorder causing a binocular dysfunction. Patching or penalization of the good eye has been the gold standard of treatment for many years. This forces the brain to focus on the image received by the affected eye.
But this treatment has its limitations.
- Children are non-complaint to patching
- Prolonged treatment which can go on years
- 15%- 50% may be left with residual amblyopia
- 20%-50% may have recurrent amblyopia on stopping the treatment
- Being mono ocular treatment, many patients never develop higher binocular vision function of stereopsis
- It is not recommended beyond the age of 9 years
The current concept is that Amblyopia is a binocular dysfunction and it is caused because of the suppression by the ocular dominance columns of the dominant eye over the non-dominant eye at the level of cerebral cortex.
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. This contrast differentiation removes the inter ocular suppression in the ocular dominance coloumns and results in visual gain of the amblyopic eye.
Bynocs now offers treatment for Amblyopia in the form of games. Treatment is based on the principle of Dichoptic therapy where both the eyes are made to view images with different levels of contrast. Patient is made to play games on a patented software with both the eyes open and wearing special anaglyph glasses.
There are a variety of 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 in 2 weeks and a good result can be expected in 6-8 weeks in appropriate cases.
Bynocs provides a comprehensive software-based Amblyopia management and treatment program package, including diagnosis and therapy, to ophthalmologists and eye care specialists.
Advantages of Bynocs:
- Good compliance as children love to play games
- 90% success rate
- No recurrence
- Being a binocular treatment, develops stereopsis
- No incidence of Diplopia
- Successful in managing Adult amblyopia
