Role of Vision Therapy in Autism Spectrum Disorder (ASD): Benefits & Techniques

Autism Spectrum Disorder (ASD) encompasses a range of developmental conditions marked by challenges in social interaction, communication, and behaviour. One often overlooked but a significant area of concern is visual processing. Individuals with ASD may experience unique difficulties with how they perceive and interpret visual information

This article delves into how these visual processing issues affect children with ASD and explores potential interventions. Vision therapy emerges as a promising approach to address these difficulties by strengthening visual skills and improving overall visual processing.

Understanding the connection between visual processing and ASD symptoms is crucial for developing effective strategies and support for individuals on the spectrum.

Visual Processing in ASD

Signs of Vision Problems in ASD

Many autistic behaviours actually may be indicative of undiagnosed vision problems. In some children, this amblyopia may be manifested as a "lazy eye," where one eye doesn't see as well as the other. Sensitivity to light and eye misalignment, which may manifest as eye turning or rolling, are also very common.

Other children may not be able to track moving objects easily or may look past or at objects beyond rather than directly at them. However, difficulty with making or maintaining eye contact can be an indicator of a vision problem. They may do some visual stimming like flapping fingers up in front of the eyes, or they may view objects on the side of their eyes.

Other factors related to vision problems include extreme fear or lack of fear of heights, and problems with reciprocal play, difficulty engaging with others in a back-and-forth manner. It's important to recognize these signs because addressing vision problems can do much to make things easier about daily functioning and interactions for a child.

with ASD often face various visual perception challenges that can impact their daily lives. Eye movement disorders, such as difficulty making quick shifts in focus or tracking moving objects smoothly, can make it hard to follow visual information.

Eye tracking issues may also be present, where a person struggles to keep up with moving objects or text. Binocular vision dysfunction is another common problem, causing difficulties in coordinating both eyes, which can result in double vision, blurred vision, eye strain, headaches, and poor depth perception.

Visual processing deficits are also prevalent, making it challenging to interpret visual information such as recognizing faces, understanding emotions, or distinguishing shapes and colours. These difficulties can affect how individuals with ASD interact with their environment and people around them.

Vision Therapy for ASD

This vision therapy course is designed to improve the connection between the eyes and the brain by incorporating exercises for both eyes individually and using visual aids like lenses and prisms to help the development of higher perceptual skills and additional visual processing.

Vision therapy can make a world of difference in how children with ASD understand their environment. That can make them finally feel safe and more secure, therefore lessening, by default, behaviours associated with anxiety and fear, such as difficulty with eye contact and verbal communication.

These therapy programs direct attention to a few key aspects: enhancement of central vision, building up of peripheral stability, rising coordination of the eyes, and betterment in visual processing. Vision therapy helps children to see and relate themselves to the surrounding environment more effectively by focusing on these areas.

One of the means employed in vision therapy involves yoked prism lenses. These lenses correct spatial misjudgments by adjusting image position so that alignment better matches the brain's expectations. This enhances adjustment in posture, balance, and comfort, thereby enriching a child's development.

To summarize, difficulties ensuing from ASD can be managed through vision therapy by enhancing clarity of vision and reducing the resultant behavioural problems.

Research on Vision Therapy for ASD

Research studies have been going on in vision therapy among children with autism. A study concluded vision therapy immensely improved the skills in terms of vision among autistic children, including both verbal and non-verbal.

Of the children studied, one showed great improvement in oculomotor skills, visual perception, and visuospatial ability after 15 weeks of systematic vision therapy. This was also manifested in daily activities in terms of increased independence over personal care and social interaction.

It confirms that although vision therapy might be helpful in some regards, it remains largely unacceptable and unvalidated as a means of treatment for ASD. Indeed, some experts admit that eye exercises can help with some particular problems with vision, but they don't have any proof of their effectiveness in reducing the symptoms of autism.

While vision therapy is indeed very promising in supporting the visual and daily living skills of children with autism, it requires further research to firmly establish effectiveness and explore the best way to integrate it into ASD treatment plans.
