Effects of Birth Weight on Anterior Eye Segment Measurements in Full-Term Children by Galilei Dual-Scheimpflug Analyzer

Overview

This study evaluates the effects of birth weight (BW) on ocular anterior segment parameters in preschool children using the Galilei Dual-Sheimpflug Analyzer (GD-SA). Children were measured by GD-SA and relationships between all anterior segment parameters obtained by this device and birth weight were analyzed.

Study Type

  • Study Type: Observational [Patient Registry]
  • Study Design
    • Time Perspective: Cross-Sectional
  • Study Primary Completion Date: March 2013

Detailed Description

Preschoolers, who were born heavier, had thicker cornea and lens, longer axial length, and flatter corneal curve. The thicknesses and axial curves of central cornea within 7mm may be particularly associated with BW.

Interventions

  • Device: Galilei Dual-Scheimpflug Analyzer
    • Measuring of Anterior Segment by Galilei Dual-Scheimpflug Analyzer

Arms, Groups and Cohorts

  • Birth Weight
