Figure 5. Quantitative Retinopathy of Prematurity (ROP) Vascular Severity Score Distribution in a Cohort of Infants With Treatment-Requiring Disease Who Received Laser Photocoagulation and Who Required Retreatment With Laser vs Those Who Required No Retreatment.

Mean scores are displayed 4 weeks before and after treatment, and the number of clinical examinations is shown at each time. At treatment and 1, 2, and 3 weeks after treatment, retreated eyes had significantly higher ROP vascular severity scores than eyes that never required retreatment. Error bars indicate 95% CIs.
