Insights
Small-for-gestational age (SGA) infants show higher rates of retinopathy of prematurity (ROP) and more severe disease compared to appropriate-for-gestational age (AGA) infants. This finding highlights the need for vigilant eye screening in high-risk premature infants.
Area of Science:
- Neonatal ophthalmology
- Perinatal medicine
- Public health
Background:
- Retinopathy of prematurity (ROP) is a significant cause of visual impairment in premature infants.
- Small-for-gestational age (SGA) infants represent a vulnerable population with potential for increased ROP risk.
- Understanding ROP incidence in SGA versus appropriate-for-gestational age (AGA) infants is crucial for targeted screening.
Purpose of the Study:
- To compare the incidence and severity of ROP between SGA and AGA infants.
- To evaluate ROP outcomes in premature infants undergoing routine eye screening.
- To inform ROP screening protocols for high-risk neonates.
Main Methods:
- Retrospective analysis of eye screening data for infants born <1500 g or <32 weeks gestational age.
- Comparison of ROP stages (any, severe, treated) between SGA and AGA infants.
- SGA defined as birth weight below the 10th percentile for gestational age.
Main Results:
- 23% of 1413 screened infants were SGA.
- SGA infants (gestational age 26-31 weeks) had significantly higher rates of any ROP (p<0.01).
- SGA infants showed increased likelihood of severe ROP across gestational age subgroups (p<0.01 to 0.01).
Conclusions:
- SGA infants are at significantly higher risk for developing ROP and more severe forms of the disease.
- Findings underscore the importance of ROP screening for SGA infants.
- This study contributes to understanding ROP disparities in premature infants.
Aim:
To compare the incidence of retinopathy of prematurity (ROP) in small-for-gestational age (SGA) infants compared with appropriate-for-gestational age (AGA) infants undergoing eye screening in the Lothian region of south east Scotland 1990-2004.
Methods:
All infants in Lothian born with birth weight <1500 g and/or gestational age <32 weeks underwent eye screening by two experienced paediatric ophthalmologists. The presence of any stage of ROP (1-5), severe (stage 3 or greater) ROP and treated ROP was compared between the SGA and AGA infants using chi(2) or Fisher exact tests. SGA was defined as birth weight below the 10th centile for gestational age.
Results:
A total of 1413 babies with birth weights <1500 g and/or gestational age <32 weeks underwent eye screening; 329 (23%) were SGA. SGA infants born at gestational ages 26-31 weeks were more likely to develop any stage of ROP (p<0.01) than their AGA peers. SGA infants were also more likely to develop severe ROP (gestational age 26-27 weeks, p<0.01; 28-29 weeks, p = 0.01; 30-31 weeks, p = 0.01).
Conclusions:
SGA infants who underwent eye screening in the Lothian region of south east Scotland from 1990 to 2004 were significantly more likely to develop ROP and more severe disease than AGA infants.
