Refraction of 1-year-old children after atropine cycloplegia
Insights
This study examined refractive errors in 1648 infants. Significant associations were found between anisometropia and both hypermetropia and astigmatism, highlighting potential early vision concerns.
Area of Science:
- Ophthalmology
- Pediatric Optometry
Background:
- Refractive errors in infants can impact visual development.
- Early detection and understanding of refractive anomalies are crucial for timely intervention.
Purpose of the Study:
- To report the prevalence of refractive errors, including hypermetropia, astigmatism, and anisometropia, in a cohort of 11- to 13-month-old children.
- To investigate the associations between anisometropia and other refractive conditions.
Main Methods:
- Cycloplegic refraction using 1% atropine was performed on 1648 children aged 11-13 months.
- Statistical analysis was used to determine the significance of associations between different refractive error types.
Main Results:
- 11.83% of children exhibited bilateral hypermetropia (≥ +2.00 D).
- 13.23% had astigmatism (≥ +1.50 D) in one or both eyes.
- 6.5% presented with anisometropia, which was significantly associated with both hypermetropia and astigmatism.
Conclusions:
- Anisometropia shows a strong statistical association with bilateral hypermetropia and, even more strongly, with astigmatism in infants.
- These findings underscore the importance of comprehensive infant eye exams to identify and manage refractive errors early.
Abstract:
The refractions of 1648 children aged 11 to 13 months are reported. Atropine 1% was used for cycloplegia. 11.83% of the children had bilateral hypermetropia of +2.00 or more D. 13.23% of them had +1.50 or more D astigmatism in one or both eyes, and 6.5% had anisometropia. Anisometropia was significantly (P=0.000 001%) associated with bilateral hypermetropia, but even more significantly (P=0.000 000 4%) associated with astigmatism of +1.50 or more D in one or both eyes.
