Preterm infants showed improved vision by age one, with 64% having normal sight. However, low birth weight and shorter gestation increased risks for myopia and other refractive errors, necessitating regular eye exams.

Area of Science:

  • Ophthalmology
  • Neonatology
  • Developmental Pediatrics

Background:

  • Preterm birth is associated with various health complications.
  • Visual development in preterm infants requires careful monitoring.
  • Refractive errors can impact long-term visual outcomes.

Purpose of the Study:

  • To assess visual development and refractive error incidence in preterm neonates.
  • To identify risk factors associated with visual impairments in this population.
  • To establish follow-up guidelines for preterm infants' eye health.

Main Methods:

  • Longitudinal follow-up of 50 preterm neonates at 6 months and 1 year of age.
  • Comprehensive ophthalmological examinations including visual acuity and refractive error assessment.

  • Correlation analysis between gestational age, birth weight, asphyxia, and ophthalmological findings.

    • Main Results:

    • At 6 months, no infants had normal vision; by 1 year, 64% achieved normal vision.
    • Incidence of myopia was 16% and hypermetropia was 20% at 1 year.
    • Lower gestational age and decreased birth weight were linked to higher refractive error incidence, particularly myopia in infants ≤2000g birth weight.

    Conclusions:

    • Preterm infants' visual function can improve significantly by one year of age.
    • Gestational age and birth weight are critical factors influencing refractive error development.
    • Routine ophthalmological screening at one year is recommended for all preterm infants, with further follow-up.
