Insights
Current ROP screening relies on birth weight and gestational age. Postnatal weight gain tracking offers improved prediction for retinopathy of prematurity (ROP), potentially reducing necessary eye exams.
Area of Science:
- Neonatal Medicine
- Ophthalmology
- Pediatrics
Background:
- Current retinopathy of prematurity (ROP) screening uses basic birth weight and gestational age criteria.
- Postnatal weight gain monitoring, a proxy for insulin-like growth factor 1, may integrate additional ROP risk factors.
- Existing models incorporating weight gain show promise in ROP risk assessment.
Purpose of the Study:
- To evaluate the efficacy of postnatal weight gain models in predicting ROP risk.
- To compare the predictive accuracy of weight gain-based models against current screening guidelines.
- To assess the potential reduction in ROP examinations through improved risk stratification.
Main Methods:
- Review of studies utilizing weight gain parameters (e.g., WINROP, ROPScore, CHOP ROP) for ROP risk assessment.
- Comparison of ROP incidence and examination rates between weight gain models and traditional methods.
- Analysis of the potential impact on neonatal care resource allocation.
Main Results:
- Weight gain-based models demonstrate accurate ROP risk assessment.
- These models may significantly reduce the number of ROP examinations required.
- Improved risk stratification compared to current birth weight and gestational age guidelines.
Conclusions:
- Incorporating postnatal weight gain into ROP screening models enhances predictive accuracy.
- This approach offers a potential reduction in unnecessary ROP examinations.
- Further large-scale studies are needed, particularly in diverse neonatal care settings.
Abstract:
Current ROP screening guidelines represent a simple risk model with two dichotomized factors, birth weight and gestational age at birth. Pioneering work has shown that tracking postnatal weight gain, a surrogate for low insulin-like growth factor 1, may capture the influence of many other ROP risk factors and improve risk prediction. Models including weight gain, such as WINROP, ROPScore, and CHOP ROP, have demonstrated accurate ROP risk assessment and a potentially large reduction in ROP examinations, compared to current guidelines. However, there is a need for larger studies, and generalizability is limited in countries with developing neonatal care systems.
