Based on their current results and previous published studies, they propose a mechanism for the first phase of ROP pathogenesis. In this model, they suggest that a low-energy intake during the first 4 weeks of life can lead to arrested vascularisation. We commend the authors for this observation as well as for their comprehensive review of ROP pathogenesis.

However, although …
