Summary
This study found few retinal degenerative features in children, with parapapillary atrophy (PPA) being the most common finding. Smaller cup-to-disk ratios were observed in myopic children, and disk rotation varied with myopia severity.
Area of Science:
- Ophthalmology
- Pediatric Ophthalmology
- Retinal Imaging
Background:
- Understanding pediatric eye health is crucial for early detection of potential vision impairments.
- Baseline retinal and optic disk characteristics in children require further investigation.
Purpose of the Study:
- To characterize the baseline retinal and optic disk features in a pediatric cohort.
- To investigate the prevalence of retinal degeneration and optic disk anomalies in children with and without myopia.
Main Methods:
- Cross-sectional study involving 679 myopic and 100 emmetropic children aged 8–13 years.
- Utilized digital retina imaging and cycloplegic autorefraction.
- Assessed vertical/horizontal cup-to-disk (CD) ratios, CD area ratio, parapapillary atrophy (PPA)-to-disk area ratio, and disk rotational angle.
Main Results:
- Lattice degeneration prevalence was 0.15%; no other retinal abnormalities were detected.
- Increased PPA-to-disk area ratio correlated with longer axial length, higher myopia, and older age.
- Myopic children had smaller CD ratios; severe myopia showed disk rotation less pronounced than in emmetropia or mild myopia.
Conclusions:
- Degenerative features, apart from PPA, were uncommon in this pediatric cohort.
- Findings suggest that PPA is a notable characteristic in pediatric myopia.
- Optic disk morphology varies with refractive error and myopia severity in children.
