There are a lot of concerns around amblyopia treatment in adults. Whilst some problems are quite genuine—some are just misleading! The fundamental issue is that adults don’t grow! This means although the body makes constant repairs for daily wear & tear, it doesn’t always make adaptive changes to its core systems.
Now, this is a very generalized fact that often accounts for notions such as—it is challenging to learn something new as an adult, or it is difficult to cure chronic illnesses in adults.
But, this generalized fact—is a half-truth—a lame means to establish the multifaceted reality of amblyopia treatment in adults. With modern technology and the right kind of treatment plan, amblyopia is very much treatable in early and peaking adults.
Procedures like blurring vision therapy, lazy eye exercises, and eye patching were the traditional treatment options for lazy eyes in adults. Unfortunately, they failed to deliver long-lasting results in the majority of the cases. Thanks to technical innovations, in recent years many new technology-dependant therapies have been developed and validated.
A study on Amblyopia treatment of adults with dichoptic training using a VR-based procedure—was conducted on adults, with anisometropic amblyopia, ranging between the ages 17-69 years. The study revealed significant improvements in visual acuity after only 8 sessions (of 40 minutes each.)
Another study observed the effectiveness of a novel, custom-made, action video game based on dichoptic therapy in treating anisometropic and strabismic amblyopia. The results concluded that game training was more effective (especially in strabismic amblyopia) in recovering visual acuity than supervised patching.
It is true, that, traditional treatment options like patching, corrective lenses, and lazy eye exercises often fail to yield a permanent cure for amblyopia in adults. But, why?
Having addressed the real issues, let’s take a look at how the dichoptic theory-based video game therapies work their way around the above-mentioned complications and offer greater effectiveness for amblyopia treatment in adults.
The Dichoptic theory states that both our eyes share a rivalry among themselves. When seeing, both our eyes capture slightly different images in terms of depth, contrast, alignment, and details. Now for some individuals, when fusing both images (for generating a single coherent image) the brain tends to suppress certain visual stimuli received by one eye, and prioritize the stimuli received by the other eye. Over time, this competition continues and one eye gets repeatedly prioritized over the other—for those certain stimuli. Eventually, the visual abilities, responsible for the suppressed visual stimuli in the eye that repetitively receives lesser priority from the brain, get impaired or weak. The video games for lazy eye treatment in adults are developed to specifically target such impaired/weak visual abilities.
Dichoptic-therapy-based video games are a form of treatment for amblyopia that use video games to provide visual stimulation to the patient. The goal of these games is to strengthen the neural connections between the eye and the brain and help the brain rewire itself to improve the patient’s vision.
Dichoptic therapy is a specific approach that presents different images to each eye, this is a way to force the brain to use both eyes together in a coordinated way, improving the amblyopic eye vision.
These games are typically designed to target specific visual abilities that are impaired in amblyopia, such as stereo-acuity (the ability to see depth), contrast sensitivity (the ability to see details in different lighting conditions), and vernier acuity (the ability to see small details and alignments).
To accomplish this, the games are designed to present different images to each eye, for example, an image for the affected eye, which is the amblyopic eye, and a different image for the non-affected eye. This creates a visual conflict in the brain, forcing it to work harder to fuse the two images together and process the visual information coming from both eyes.
Some common features of dichoptic-therapy-based video games include:
At Bynocs, we develop dichoptic therapy-based video games that can offer customized stimuli, intensity, and frequency for adult patients. Despite the limitations of an adult brain and ocular anatomy, our amblyopia treatments for adults prove effective—because we customize the video game to the point where it precisely focuses on the unique amblyopic conditions of a particular patient.
We have dedicated eye care professionals to personalize the video-game-based therapies to your unique condition—and determine whether you should be using a combination of other treatments, such as patching and corrective lenses. At Bynocs, we also provide vision therapy software that can be used by your eye care professional to track and monitor your progress. Our revolutionary vision therapy software AmblyGo is a strong example of the new possibilities in eyecare with the support of technology. And, how the concerns around adult amblyopia can be strategically tackled at any age.
