Risk Calculator for Retinopathy of Prematurity Requiring Treatment

Area of Science:

• Ophthalmology
• Neonatology
• Perinatal Medicine

Background:

• Retinopathy of prematurity (ROP) is a leading cause of visual impairment in premature infants.
• Early vascular delay is a critical risk factor for developing ROP that necessitates treatment.
• Identifying predictive factors for ROP is crucial for timely intervention and improved outcomes.

Purpose of the Study:

• To investigate the association between ROP requiring treatment and key risk factors.
• To quantify the impact of temporal avascular area and mechanical ventilation duration on ROP treatment necessity.
• To develop a predictive model for ROP treatment risk in premature newborns.

Main Methods:

• An observational retrospective case-control study was conducted.
• Retinal examinations were performed on 228 premature infants at 4 and 6 postnatal weeks.
• Temporal avascular area (in disc diameters) and mechanical ventilation duration (in days) were measured.

Main Results:

• Increased duration of mechanical ventilation was significantly associated with a higher risk of ROP requiring treatment (8.1% increase per day).
• A larger temporal avascular area was also strongly correlated with increased ROP treatment risk (111% increase per disc diameter).
• An online calculator and table were developed to estimate ROP treatment risk based on these factors.

Conclusions:

• The temporal avascular area and duration of mechanical ventilation are significant predictors of ROP requiring treatment.
• These factors should be considered during initial newborn examinations to assess ROP risk.
• Early identification of high-risk infants can guide proactive management and potentially prevent severe visual outcomes.
