    Aim: Retinopathy of prematurity (ROP) risk factors have been investigated in population-based studies from most global regions. No such studies are available from Sub-Saharan Africa (SSA), where improved neonatal care is increasing the survival of preterm infants at risk of ROP. Methods: A population-based study was conducted in infants born in Cape Town, South Africa, from 1 May 2022 to 31 January 2023. The screening criteria were birth weight < 1250 g or gestational age < 32 weeks. The data were extracted from the Retinopathy of Prematurity South African register. Results: The study included 378 screened infants, 115 (30.4%) of whom developed ROP. In the multiple regression analyses, lower birth weight was an independent ROP risk factor, OR 1.3 95% CI 1.2–1.5, p < 0.001. Surgical necrotising enterocolitis (NEC) was the only other independent ROP risk factor, OR 5.8 95% CI 1.6–21.0, p = 0.007. Infants with birth weight < 1000 g were 39.4% (130/378) of those screened and more likely to develop ROP compared to larger infants, OR 2.4 95% CI 1.5–3.9, p < 0.001. Conclusion: Birth weight remained a significant ROP risk factor, especially for those born weighing less than 1000 g. These infants represented a larger proportion of screened infants compared to previous Sub-Saharan African studies.
