Extremely preterm infants show favorable long-term visual outcomes, with visual acuity linked to cognitive and motor skills. This suggests improved neonatal care positively impacts visual development in high-risk newborns.

Area of Science:

  • Neonatology
  • Ophthalmology
  • Developmental Pediatrics

Background:

  • Neonatal intensive care advancements have increased survival rates for extremely preterm infants.
  • Long-term visual function and ocular development require further investigation in this vulnerable population.

Purpose of the Study:

  • To assess long-term visual function and ocular development in extremely preterm infants.
  • To correlate visual outcomes with neonatal morbidity and neurodevelopmental status.

Main Methods:

  • An unselected cohort of 52 extremely preterm infants (22-27 weeks gestation) underwent comprehensive eye examinations.
  • Visual acuity, refractive error, binocular function, and accommodation were evaluated.
  • Cognitive (WPSSI-R) and motor (ABC test) functions were assessed.

Main Results:

  • No infants were blind or visually impaired; 46% had subnormal visual acuity (logMAR ≥0.1).
  • Most infants were emmetropic or hypermetropic (90%); 51% had latent strabismus.
  • Visual acuity correlated significantly with performance IQ and motor abilities (p < 0.05).

Conclusions:

  • Survivors of extreme prematurity demonstrate a more favorable long-term visual prognosis than previously reported.
  • Performance IQ and motor function are significant predictors of visual acuity in this cohort.
