[Evaluation of published recommendations for screening studies of retinopathy of prematurity]
Insights
German guidelines for screening preterm infants for retinopathy of prematurity (ROP) were evaluated. Infants weighing under 1500g, under 2000g with prolonged oxygen, or critically ill require screening by 6 weeks postnatal.
Area of Science:
- Ophthalmology
- Neonatology
- Public Health
Context:
- Retinopathy of prematurity (ROP) is a leading cause of blindness in premature infants.
- German guidelines for ROP screening vary and are partially contradictory.
- Early detection and intervention are crucial for preventing ROP-related vision loss.
Purpose:
- To evaluate the effectiveness and consistency of different German guidelines for screening retinopathy of prematurity (ROP).
- To analyze data from preterm infants to inform optimal ROP screening criteria.
- To provide evidence-based recommendations for ROP screening protocols.
Summary:
- Analysis of 1219 preterm infants revealed ROP in 7.2%, with most cases in infants under 1500g birth weight.
- Threshold ROP occurred in 3% of infants, primarily those under 1230g.
- Recommended screening criteria include birth weight <1500g, <2000g with prolonged oxygen, or severe illness, with the first exam at 6 weeks postnatal or 31 weeks postmenstrual age.
Impact:
- Refined screening criteria for retinopathy of prematurity can improve early detection rates.
- Standardized ROP screening protocols can reduce the incidence of preventable blindness in preterm infants.
- Evidence-based guidelines support better clinical decision-making in neonatal eye care.
Purpose:
Evaluation of different and partially contradictory guidelines for screening for retinopathy of prematurity published in Germany.
Patients:
The data on 1219 preterm infants examined in Bern (n = 900) and Berlin (n = 319) were analyzed. A total of 680 preterm infants (56%) had a birth weight below 1500 g. The remaining infants were examined because oxygen had to be supplied or surgery done before or around the estimated delivery time.
Results:
Stage 3 retinopathy was found in 88/1219 (7.2%) preterm infants. Only 5/88 infants weighed more than 1500 g at birth. Three of these infants had a birth weight below 2000 g and needed supplemental oxygen for a prolonged period of time. The other 2 infants had birth weights of more than 2000 g and were severely ill. Of 1219 preterm infants, 37 (3%) developed threshold retinopathy (according to the criteria of the multicenter trial); 35/37 infants weighed less than 1230 g at birth. The remaining 2 children (1650 g and 2185 g birth weight) were severely ill.
Conclusions:
Preterm infants should be screened for retinopathy of prematurity: (1) if the birth weight is below 1500 g; (2) if the birth weight is below 2000 g and oxygen supply was necessary for more than 30 days; (3) if infants are very sick or must undergo multiple surgery before term. The first examination should be scheduled for the 6th week postnatal and not before 31 weeks postmenstrual age.
