The impact of a multidisciplinary intervention to reduce severe retinopathy of prematurity in Kampala, Uganda

To address the threat of retinopathy of prematurity (ROP) in Sub-Saharan Africa (SSA), the Stop Infant Blindness in Africa (SIBA) project introduced a comprehensive program, including subspecialty training and oxygen management equipment.

A before-and-after retrospective cohort study compared preterm infants < 1750 g or < 34 weeks’ gestation before (2022) and after (2023) program implementation. Outcomes included: the proportion with severe ROP, the proportion with Zone III vascularization on first examination, and factors associated with severe ROP.

Overall, 140 infants were screened before and 122 after program implementation. The proportion with Zone III vascularization increased from 16.1% (N = 11) pre-intervention to 44.9% (N = 32) post-intervention (p = 0.001). The proportion with severe ROP decreased from 27.8% (N = 19) to 12.8% (N = 9, p = 0.03). Factors predicting severe ROP on adjusted analyses were gestational age and blood transfusion.

In SSA, introduction of a comprehensive program to prevent and treat ROP can decrease the risk of severe ROP.
