Overcoming Amblyopia or the Lazy Eye

Amblyopia, commonly known as ‘Lazy eye’, is a vision-related disorder that affects young children. And you can get this condition treated using our Amblyopia therapy software!

Amblyopia treatment surgery in India can be a costly affair and can also be painful, especially for children. Our software requires you to wear our blue-red sunglasses and play our patented games!

Let's understand Amblyopia

In some children, only one of the two eyes focuses properly. This is a vision problem called lazy eyes (the medical term for this is Amblyopia). It is caused when the two eyes send different images to the brain. For example, it may happen if one of the eyes is more nearsighted, farsighted, or has more astigmatism (refractive error) than the other, or if the child has a squint. The brain then primarily processes the information coming from the better eye, ignoring the other. If unnoticed or untreated, it can continue to affect in later years. It is estimated that about 4% of children and between 1-5% of the adult population is affected by this visual impairment.

To understand this condition better, let us see how we actually see things.

Understanding Binocular Vision

Vision develops in the first few years of life as the brain starts interpreting visual signals coming from the eyes. What we ‘see’ results from signals sent from the eyes to the brain. Usually, the brain receives signals from both (bi) eyes (ocular) simultaneously. However, due to the placement of the eyes, the visual information collected by each eye differs slightly. If all is well, the brain can use these differences to coordinate eye movements and judge distances so that a wholesome meaningful 3D visual is created, and that is what we ‘see.’

What Causes Amblyopia/Lazy Eye? Does Amblyopia treatment surgery exist?

A lazy eye may be an outcome of abnormal visual experiences in early life.

The eyes, visual pathways, and brain centres are constantly developing and maturing in the first few years of life. Occasionally, when one of the eyes does not function correctly, the brain tends to rely on the visual impulses coming from the stronger eye. If left untreated, the stronger eye continues to develop further, and the weaker eye can worsen. This visual imbalance is known as Amblyopia.
Bynocs has been specifically developed to assist Ophthalmologists and Optometrists in the accurate assessment and management of Binocular Vision anomalies through a range of software-based eye treatment activities.
Certain abnormalities in the eyes during the growing years and/or later life can cause an eye to develop a poor vision and result in Amblyopia, such as:

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. In addition, uncorrected refractive errors can strain the eye muscles, which have to work harder to achieve a focussed vision.
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 ignore the weaker eye.

Muscle Imbalance or Strabismus

Our eyes have a set of muscles that help with 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.

Cataracts

A cataract is a condition that requires urgent attention to prevent long-term damage. A cloudy lens, i.e., cataract, may obscure vision in the eye and lead to Amblyopia in the affected eye. Cataracts can occur in infancy as well as develop in later life.

What Are The Symptoms of Amblyopia/Lazy Eye?

Amblyopia can develop in childhood and may continue to persist in adulthood as well.

Symptoms in Children

When a child develops a lazy eye, parents may observe that their child faces difficulty focusing on objects, or they squint or shut one of the eyes to view the objects or surroundings clearly. Often, the child’s eyes may appear to turn inward, outward, or they may not work together in coordination.

 

Older children may also complain of poor perception of depth and an inability to view things clearly from a distance, such as writing on the classroom board.

When children develop such symptoms, It is important to consult a pediatric ophthalmologist as soon as possible to enable early treatment.

Symptoms in Adults

If a child with lazy eyes does not receive early treatment, the condition may worsen and persist in adulthood. Sometimes, a child may be undiagnosed for visual disturbances at an early age and may receive a diagnosis as they grow older, when visual disturbances intensify.
The common complaints of adults having lazy eyes are:
  • Blurred or double vision
  • Uncoordinated eye movements
  • Poor depth perception
  • Squinting or closing one eye to view better
Childhood Amblyopia Adult Amblyopia
● The child may be seen squinting or shutting one eye.
● Parents may be able to see uncoordinated eye movements in their child.
● The child may complain of inability to view the classroom board clearly.
● Blurred or double vision
● Poor depth perception
● Increased complaints of eye strain.

Amblyopia Therapy Software - How Is Amblyopia/Lazy Eye Treated?

If left untreated, a lazy eye may worsen and lead to permanent visual impairment. Therefore, the goal of treatment is to help improve vision in the lazy eye and thereby optimize binocular vision.
The traditional treatment approaches to treat the lazy eye include:
When a lazy eye develops due to near-sightedness or far-sightedness or an unequal refractive error in both eyes, corrective eyeglasses can help improve the vision and prevent further deterioration.

Eye-Glasses

Surgery

In severe cases such as cataracts, immediate surgery is essential to prevent loss of vision. Surgery may also be performed for strabismus (muscle weakness of the eyes) or to improve the refractive error. Lazy eye surgery for adults can be a risky affair.

Patching or Overpowering the Normal Eye

Patching

Patching is the most commonly advised treatment for lazy eyes in children. In this, a small eye patch is applied to the normal eye in an attempt to obscure its vision for a few hours daily. This way, the brain is trained to recognize the visual impulses coming from the weaker eye.

Penalization using Eye Drops

Eye drops are instilled into the normal eye and cause a temporary blurring of vision in the normal eye. This prompts the brain to turn towards visual impulses coming from the weaker or lazy eye.
However, the success of these approaches depends on how regularly the child is in applying the patches/eye drops. Most children do not like this kind of patching and tend to resist it. Very often, parents do not apply the patch to avoid social stigma.
Patching or penalization can also lead to visual problems in the normal eye, and this approach does not help correct the adult lazy eye.

Limitations with Patching/Penalisation

  • Lesser success rates and higher incidence of residual visual deficit.
  • Prolonged treatment over many years is essential for optimal results.
  • Monocular treatment – treats one eye only.
  • Chances of visual disturbances occurring in the stronger eye.
  • Possibility of relapse once patching is discontinued.
  • Discomfort to the eyes and the child due to eye-drop installation or patching.
  • Patching may cause social anxiety in older children.
  • Non-compliance to patching due to peer pressure.
  • Time is of the essence, patching is not helpful unless started at an early age (<9years).
  • Not useful to treat Lazy Eye in adults.
While it is true that for treating the Lazy eye, time is of the essence, and most treatments are directed towards children, there are newer treatment technologies available that can be used to improve eyesight in adults and the elderly population as well.

"It is a myth that lazy eyes can be treated only in early childhood. Adults too can overcome their lazy eyes with recent advances in technology that helps achieve perfect vision."

Dichoptic Eye Treatments

Treatment for 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.

Dichoptic technology can help improve vision in children as well as adults.
