Summary

Extremely low birth weight (ELBW) infants show lower visual acuity than full-term infants, particularly after 9 months. Neonatal complications like bronchopulmonary dysplasia impact long-term visual function.

Area of Science:

  • Neonatalogy
  • Ophthalmology
  • Developmental Pediatrics

Background:

  • Increased survival rates of extremely low birth weight (ELBW) infants necessitate understanding their developmental outcomes.
  • ELBW infants face a higher risk of visual impairment, requiring accurate assessment tools.
  • Current understanding of visual functioning in ELBW survivors needs refinement.

Purpose of the Study:

  • To assess grating visual acuity in survivors of extreme prematurity.
  • To compare visual acuity in ELBW infants with full-term infants of similar postconceptional age.
  • To identify factors associated with visual impairment in ELBW infants.

Main Methods:

  • Utilized Teller Acuity Cards to measure grating visual acuity.
  • Assessed 26 ELBW infants with corrected ages ranging from 2 to 42 months.

  • Correlated visual acuity scores with neonatal complications and the Neonatal Medical Index.

    • Main Results:

    • Most ELBW infants' visual acuity scores were within the normal range.
    • Visual acuity was significantly lower in ELBW infants compared to full-term infants, especially after 9 months corrected age.
    • Neonatal complications, particularly bronchopulmonary dysplasia, and the Neonatal Medical Index were linked to lower visual acuity.

    Conclusions:

    • ELBW infants exhibit delayed visual acuity development compared to their full-term peers.
    • Neonatal health status significantly influences visual outcomes in ELBW survivors.
    • Early identification and monitoring of visual function are crucial for ELBW infants.
