Summary
This study established normative data for saccadic eye movements (SEMs) in adolescents, revealing age-related changes in prosaccades (PSs) and antisaccades (ASs). These findings aid in diagnosing conditions affecting adolescent eye movements and cognitive function.
Area of Science:
- Ophthalmology
- Neuroscience
- Developmental Psychology
Background:
- Saccadic eye movements (SEMs) are crucial for visual attention and clinical assessment.
- Deviations in SEMs aid in diagnosing neurologic, otoneurologic, and psychiatric conditions in patients.
- SEMs are vital for identifying conditions like schizophrenia, ADHD, and Alzheimer's disease.
Purpose of the Study:
- To establish normative data for prosaccades (PSs) and antisaccades (ASs) in healthy adolescents aged 12-17 years.
- To analyze age-related differences in SEM parameters within this age group.
Main Methods:
- A cross-sectional study involving 138 healthy adolescents aged 12-17 years.
- Participants underwent assessment of PSs and ASs using commercially available equipment.
- Data collected included accuracy, latency, velocity, and directional error.
Main Results:
- Normative values for PSs and ASs were established.
- Significant age-related reductions in AS latency and directional error were observed with maturation.
- Male participants exhibited lower AS latencies compared to females, with specific age-related velocity differences noted.
Conclusions:
- Normative SEM data for adolescents aged 12-17 years were successfully established.
- Age-related variations in AS latency and directional error highlight developmental changes.
- These normative values can aid in detecting oculomotor dysfunction and cognitive impairment in adolescents.
