Insights

Retinopathy of prematurity (ROP) screening guidelines may miss infants in developing countries. This study found ROP in premature infants older and heavier than typically recommended for screening.

Area of Science:

  • Ophthalmology
  • Neonatology
  • Public Health

Background:

  • Current retinopathy of prematurity (ROP) screening guidelines, established by the American Academy of Pediatrics and the American Association for Pediatric Ophthalmology and Strabismus, focus on infants with a birth weight of ≤1500 g and/or a gestational age of 32 weeks or less.
  • However, ROP has been observed in older and heavier infants in developing and middle-income countries, suggesting current guidelines may not be universally applicable.

Purpose of the Study:

  • To investigate the occurrence of retinopathy of prematurity (ROP) in a cohort of infants in a developing country who fall outside the standard screening criteria.
  • To determine if ROP affects premature infants who are older and/or heavier than typically recommended for screening.

Main Methods:

  • A prospective study was conducted over 16 months involving 172 infants.
  • Infants included had a gestational age of 36 weeks or younger and/or a birth weight of ≤3000 g.
  • Ophthalmic examinations were performed to identify ROP.

Main Results:

  • Retinopathy of prematurity (ROP) was identified in 4 infants older than 32 weeks' gestational age.
  • One infant diagnosed with ROP had a birth weight of 2000 g.
  • These findings indicate ROP was diagnosed in premature infants heavier than typically considered by international screening standards.

Conclusions:

  • Standard ROP screening guidelines may be insufficient for identifying all affected infants, particularly in developing regions.
  • There is a need to reconsider and potentially broaden ROP screening criteria to include older and heavier premature infants in resource-limited settings.
  • Further research is warranted to establish optimal screening protocols for retinopathy of prematurity in diverse populations.
