Relationship Between Ocular Motility and Motor Skills

Area of Science:

• Ophthalmology and Optometry
• Developmental Pediatrics
• Motor Control

Background:

• Ocular motility and motor skills are crucial for childhood development and academic success.
• Previous research suggests a link between visual function and motor performance, but specific relationships in school-age children require further investigation.

Purpose of the Study:

• To investigate the relationship between ocular motility and gross motor skills in school-age children.
• To determine if children with typical motor performance exhibit better ocular motility compared to those with motor difficulties.

Main Methods:

• A descriptive cross-sectional study involving 142 schoolchildren (mean age 7.08 years).
• Ocular motility was assessed using the computerized Developmental Eye Movement (DEM) test and the Northeastern State University College of Optometry's Oculomotor (NSUCO) test, with eye movements recorded.
• Participants were categorized into three groups based on motor performance using the Movement Assessment Battery for Children-2 (MABC-2).

Main Results:

• Children with typical motor performance demonstrated superior ocular motility, evidenced by higher percentiles in vertical and horizontal time, fewer errors, saccades, fixations, and regressions.
• Faster performance on visual tests was observed in children with typical motor skills.
• Weak to moderate correlations were found between visual test results and motor assessment outcomes.

Conclusions:

• There is a significant interconnectedness between ocular motility and gross motor skills in school-age children.
• Early assessment of both visual and motor proficiencies is recommended to identify developmental challenges.
• These findings highlight the importance of a holistic approach to child development evaluations.
