Summary
High myopia in children can indicate underlying corneal abnormalities, including keratoconus. Early corneal screening is vital for timely detection and treatment in pediatric high myopia cases.
Area of Science:
- Ophthalmology
- Corneal Imaging
- Pediatric Eye Care
Background:
- High myopia in children is a growing concern.
- Corneal topography is crucial for diagnosing conditions like keratoconus.
- Understanding corneal changes in pediatric high myopia is essential for early intervention.
Purpose of the Study:
- To evaluate topographic corneal changes in children with high myopia.
- To determine the incidence of keratoconus in this pediatric population.
Main Methods:
- Prospective study of 174 eyes in children with high myopia (ages 6-14).
- Corneal examination using Scheimpflug imaging to assess parameters like Kmax, thinnest location, and aberrations.
- Comparison of eyes with and without keratoconus.
Main Results:
- 9.2% of eyes (16/174) showed signs of keratoconus.
- Significant differences in maximum K reading, anterior, and posterior elevation were noted in keratoconus eyes.
- Higher-order aberrations, particularly vertical coma and spherical aberrations, were statistically different.
- Vernal keratoconjunctivitis and frequent eye rubbing were associated with corneal abnormalities in 37.5% of cases.
Conclusions:
- Children with high myopia may exhibit corneal abnormalities, even without significant astigmatism.
- Corneal changes are more pronounced in cases with vernal keratoconjunctivitis.
- Routine corneal examination is recommended for children with high myopia to detect and manage potential abnormalities early.
