Acknowledgement

This tool estimates the 2-week risk of treatment-requiring ROP from gestational age, postmenstrual age, and P-score (a measure of vascular severity). It should be used to assist in determining whether a 1-week vs 2-week follow-up exam is necessary. Its aim is to support, not replace, clinical judgment and is for investigational use only. It has only been validated for use on US populations.

When to Use

This tool estimates the 2-week probability of treatment-requiring ROP development. Use it for risk-based scheduling and escalation discussions within the next 14 days.
