We read the work of Teofili et al with interest. In our study we found an association between low foetal haemoglobin levels (HbF) levels and retinopathy of prematurity, but further work is required to identify a causal or predictive link. In addition, to optimising initial haemoglobin levels through delayed cord clamping when possible, managing anaemia with HbF-rich cord blood transfusions is an interesting proposition.
