Insights
New prediction models for retinopathy of prematurity (ROP) can identify infants needing treatment using only birth data. This helps reduce unnecessary screening examinations for premature infants, improving ROP care.
Area of Science:
- Neonatal ophthalmology
- Perinatal medicine
- Biostatistics
Background:
- Current screening for sight-threatening retinopathy of prematurity (ROP) is extensive, with less than 10% of screened infants requiring treatment.
- Existing prediction models for ROP treatment risk incorporate factors like birth characteristics and postnatal weight gain.
- There is a need for more efficient screening protocols to reduce examinations in low-risk infants.
Purpose of the Study:
- To develop and validate an advanced statistical prediction model for ROP treatment risk.
- To assess if birth characteristics alone can predict ROP treatment risk as effectively as models including weight measurements.
- To identify the peak age for ROP treatment risk.
Main Methods:
- Utilized advanced statistical methods on data from over 7000 infants in the Swedish ROP registry.
- Developed a prediction model based initially on birth characteristics.
- Compared the predictive performance of the birth characteristics-only model with models incorporating weight measurements.
Main Results:
- A prediction model based solely on birth characteristics demonstrated comparable accuracy in predicting ROP treatment risk to models that include weight measurements.
- The risk of requiring ROP treatment peaked at 12 weeks of age.
- Laser therapy remains the primary treatment for severe ROP, while anti-VEGF therapies are used globally with ongoing research into optimal use and long-term effects.
Conclusions:
- Birth characteristics alone are powerful predictors of ROP treatment risk, potentially simplifying screening protocols.
- The findings suggest that ROP screening can be optimized by focusing on specific predictive factors and timing.
- Further research is ongoing into ROP prevention strategies, including oxygen management, breastfeeding, and nutritional/hematological interventions.
Abstract:
With current screening for sight threatening retinopathy of prematurity (ROP) <10% of screened infants need treatment. Prediction models based on birth characteristics, postnatal weight gain and other factors have been developed to reduce examinations in low-risk infants. A model based on advanced statistics using data from >7000 infants registered in the Swedish ROP registry is being developed. Based on birth characteristics only, it appears to predict total risk of ROP-treatment as well as models including weight measurements. Treatment risk peaked at 12 weeks of age. Laser therapy is the method of choice for severe ROP. Anti-VEGF therapies are implemented worldwide despite insufficient knowledge of choice of drug, dosage and long term systemic effects. Prevention of ROP may be achieved through oxygen control and provision of the mother's breastmilk. Other interventions such as supplementation with long chain polyunsaturated fatty acids and preservation of fetal haemoglobin are investigated.
