Summary
People with intellectual disability (ID) have poor eye care attendance. Many experience vision impairment and ocular conditions, highlighting the need for routine eye exams and accessible services for this population.
Area of Science:
- Ophthalmology
- Public Health
- Intellectual Disability Research
Background:
- Vision impairment is common in individuals with intellectual disability (ID).
- This study investigates the visual status of an ID population in Portugal.
Purpose of the Study:
- To assess the visual status and eye care practices of individuals with intellectual disability in Portugal.
- To identify prevalent vision-related conditions and barriers to eye care within this population.
Main Methods:
- A vision screening protocol was applied to 134 subjects with ID during Special Olympics events.
- Evaluations included medical history, ocular health, visual acuity (VA), binocular vision, color vision, refractive error, and intraocular pressure.
Main Results:
- 50% of subjects had never attended an eye exam or did not recall attending.
- Half failed VA tests, with 13% having moderate visual impairment (VI).
- Refractive error correction reduced moderate VI to 3.7%.
Conclusions:
- The studied population exhibits low eye care attendance and high rates of vision issues.
- National strategies promoting routine eye care awareness and accessibility are crucial for mitigating prevalent conditions in people with ID.

400
Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...

01:12Visual Agnosia
689
Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round...

01:25Learning Disabilities
463
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.

1.4K
Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...

Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...

01:19Autism Spectrum Disorder
741
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.
