Axial length development in children

Area of Science:

• Ophthalmology
• Pediatric Ophthalmology
• Biometry

Background:

• Accurate measurement of ocular axial length is crucial for diagnosing and managing various pediatric eye conditions.
• Establishing normative data for axial length in healthy pediatric eyes is essential for comparison.

Purpose of the Study:

• To establish a normative model for ocular axial length in pediatric subjects without intraocular pathology.
• To analyze the pattern of axial length growth in healthy children.

Main Methods:

• Retrospective chart review of axial lengths from 330 eyes of 165 pediatric subjects examined under anesthesia.
• Inclusion criteria: absence of intraocular pathology; exclusion criteria: presence of intraocular pathology.
• Development of an axial length growth model using logarithmic regression, with stratification by age groups.

Main Results:

• The study included 330 eyes from 165 pediatric subjects with a mean age of 30.62 months.
• The steepest increase in ocular axial length was observed during the first 10 months of life.
• No statistically significant axial length growth was detected after 36 months of age.

Conclusions:

• This study provides the largest dataset of pediatric ocular axial lengths in healthy eyes.
• The developed axial length model can aid in the diagnosis and management of pediatric ophthalmic diseases.
• Normative data is critical for identifying deviations from typical growth patterns.
