Autism Spectrum Disorder01:19

Autism Spectrum Disorder

1.9K
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Focusing of Light in the Eye01:16

Focusing of Light in the Eye

6.1K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

Modeling in Therapy

823
Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.

Learning Disabilities

697
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.
Dyslexia

Summary

Visual problems in children with autism are often overlooked in developing countries. This study found significant refractive errors, primarily astigmatism, in Nigerian children with autism, highlighting the need for early detection and intervention.

Area of Science:

  • Ophthalmology
  • Developmental Pediatrics
  • Public Health

Background:

  • Visual impairments in intellectually disabled individuals are frequently neglected in resource-limited settings.
  • Autism Spectrum Disorder (ASD) can present with associated visual challenges.
  • Early identification of visual problems is crucial for overall development.

Purpose of the Study:

  • To investigate the prevalence and types of refractive errors in children diagnosed with autism.
  • To assess visual functioning in autistic children within a developing country context.
  • To emphasize the importance of ophthalmic care for this vulnerable population.

Main Methods:

  • Ophthalmic examinations were conducted on children with autism in Enugu, Nigeria.
  • Visual acuity was assessed using Lea symbols.
  • Cycloplegic refraction was performed to determine refractive errors.

Main Results:

  • 18 children with autism (aged 5-15 years) were examined, representing 85.7% coverage.
  • Prevalence of refractive errors included astigmatism (22.2%) and hypermetropia (11.1%).
  • Two children presented with optic disc pallor and maculopathy.

Conclusions:

  • Significant refractive errors, particularly astigmatism, are present in children with autism in this population.
  • Early detection and correction of refractive errors can enhance visual function and daily life activities.
  • Routine ophthalmic screening is recommended for children with autism in developing nations.
