Summary
Children with amblyopia (impaired vision) or strabismus (eye misalignment) take longer to complete multiple-choice tests. This fine motor deficit may impact academic performance in school-aged children.
Area of Science:
- Ophthalmology
- Pediatric Ophthalmology
- Developmental Neuroscience
Background:
- Strabismus and anisometropia in childhood can lead to amblyopia (reduced visual acuity) and poor stereoacuity.
- These conditions are associated with deficits in fine motor skills, potentially affecting academic tasks.
- Assessing fine motor skills in children with these visual impairments is crucial for understanding academic challenges.
Purpose of the Study:
- To evaluate academic-related fine motor performance, specifically multiple-choice answer form completion time, in children with amblyopia and strabismus.
- To compare the fine motor task completion speed of children with amblyopia and/or strabismus to that of normal controls.
- To identify potential academic implications of visual impairments related to fine motor speed.
Main Methods:
- A cross-sectional study involving 85 children (47 with amblyopia, 18 with nonamblyopic strabismus, 20 controls) aged approximately 10 years.
- Participants were instructed to transfer answers from a test booklet to a multiple-choice form as quickly and accurately as possible.
- Completion time was measured and analyzed across the different study groups.
Main Results:
- Children with amblyopia and children with nonamblyopic strabismus took significantly longer to complete the multiple-choice answer form compared to controls.
- Specifically, affected children required approximately 28% more time (around 63-68 seconds longer).
- Completion time was not correlated with the cause of the visual impairment, visual acuity, or stereoacuity.
Conclusions:
- Children with amblyopia or strabismus exhibit slower fine motor skills when completing multiple-choice answer forms.
- This increased completion time may negatively affect their performance on standardized tests and overall academic success.
- Interventions addressing fine motor skills may be beneficial for children with these visual conditions.

Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.

Some individuals interpret life events as a consequence of their personal choices and actions, while others believe that outcomes are dictated by fate or destiny. This divergence in perspective has been examined in psychological and cross-cultural studies, particularly in relation to religious faith and cultural beliefs about causality.Fate and Personal ResponsibilityPeople who emphasize personal responsibility view events as direct consequences of their decisions. For instance, breaking a leg...

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Multiple regression assesses a linear relationship between one response or dependent variable and two or more independent variables. It has many practical applications.
Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...
