Astigmatism significantly reduces oral reading fluency (ORF) in students when uncorrected. Full-time spectacle wear is recommended, especially for high astigmats, as correction improves ORF in this group.
Area of Science:
- Ophthalmology
- Pediatric Optometry
- Educational Psychology
Background:
- Astigmatism is a common refractive error affecting visual clarity.
- Reduced visual acuity can impact academic performance, including reading skills.
- Oral reading fluency (ORF) is a critical measure of reading proficiency in school-aged children.
Purpose of the Study:
- To compare ORF in students with no/low astigmatism versus those with moderate/high astigmatism.
- To evaluate the effect of spectacle correction on ORF in students with moderate and high astigmatism.
Main Methods:
- Recruited third- to eighth-grade students from a highly astigmatic population.
- Assessed refractive error using cycloplegic autorefraction; excluded students with ocular abnormalities or binocular vision disorders.
- Measured ORF using the Dynamic Indicators of Basic Early Literacy Skills (DIBELS) Next test, comparing uncorrected astigmats, corrected astigmats, and no/low astigmats.
Main Results:
- Uncorrected astigmats demonstrated lower ORF compared to no/low astigmats (p=0.011).
- No significant difference in ORF was found between no/low astigmats and best-corrected astigmats (p=0.10).
- High astigmats showed significant ORF improvement with spectacles (mean 6.55 wpm, p=0.001), unlike moderate astigmats (mean 1.87 wpm, p=0.193).
Conclusions:
- Bilateral astigmatism (≥1.00D) significantly reduces uncorrected ORF but not when best-corrected.
- Spectacle correction enhances ORF in high astigmats, suggesting benefits for reading.
- Full-time spectacle wear is advised for astigmatic students, particularly those with high astigmatism, to optimize reading performance.
