Hypothesis
How do age and sex influence eye movement characteristics in a large cohort?
Conclusion
Eye movements are sex-specific and provide normative data for comparing eye movement functions by age.
Supporting Evidence
- Eye movements provide biomarkers for disease classification with superior accuracy.
- Statistically significant differences were observed in eye movement functions between males and females.
- Normative data for eye movements can help in diagnosing neurological diseases.
Takeaway
This study shows that boys and girls, as well as men and women, move their eyes differently, and understanding these differences can help doctors diagnose brain issues better.
Methodology
Participants completed six eye movement assessments, and data were analyzed using multiple t-tests and linear regression models.
Potential Biases
The study may have biases due to unequal representation of sexes in previous research.
Limitations
The study did not control for all possible conditions affecting eye movements.
Participant Demographics
Participants included 11,871 males and 11,686 females aged 6 to 80 years, with 42.38% reporting race and ethnicity.
