Insights

Retinopathy of prematurity (ROP) affects 4.2% of infants weighing 1250-1800g. Modified screening for infants with risk factors can improve outcomes and cost-effectiveness.

Area of Science:

  • Ophthalmology
  • Neonatology
  • Public Health

Background:

  • Retinopathy of prematurity (ROP) is a significant cause of visual impairment in premature infants.
  • Optimal screening strategies are crucial for early detection and intervention, particularly in infants with specific birth weights (BW).

Purpose of the Study:

  • To determine the incidence and severity of ROP in infants with BW between 1250 and 1800 g.
  • To examine the influence of systemic conditions on ROP development in this population.
  • To evaluate the cost-effectiveness of various ROP screening guidelines.

Main Methods:

  • Retrospective review of 259 infants with BW 1250-1800 g screened for ROP over 3 years.
  • Data collected included ROP presence/severity and potential risk factors (RF): sepsis, meningitis, necrotizing enterocolitis, intraventricular hemorrhage, pneumothorax, high bilirubin, central line, prolonged antibiotics, multiple RBC transfusions, and mechanical ventilation.
  • Statistical analysis to identify predictors of ROP.

Main Results:

  • Overall ROP incidence was 4.2%. Infants with stage 3 ROP had significantly lower BW and gestational age.
  • No infant with BW > 1500 g developed treatable ROP.
  • For infants weighing 1501-1800 g, sepsis, prolonged ventilation, extended antibiotic use, multiple RBC transfusions, and central line placement were significant predictors of ROP. Infants with ROP in this weight group had at least two RF.

Conclusions:

  • Current screening guidelines identify high-risk ROP cases.
  • Modified screening criteria (BW ≤ 1500 g or BW 1501-2000 g with ≥ 2 RF) are cost-effective, yielding a $587.85 benefit per infant screened.
  • Targeted screening can optimize resource allocation and improve ROP management.
