Bronchopulmonary dysplasia (BPD) and retinopathy of prematurity (ROP) are common and important diseases in preterm infants. What these diseases have in common is altered blood vessel formation and pathological changes in the case of incomplete organ development. Multiple factors interact to cause abnormal angiogenesis, which increases the likelihood of a common pathway for both diseases. However, little is known about the specific mechanism of this balance in the occurrence and development of BPD or ROP, and there are still no animal models to explore the pathogenesis of these two diseases simultaneously. At present, there is no effective prevention program, and the treatment options include drug therapy, surgery, etc. In the future, more studies are needed to find common therapeutic targets for factors affecting angiogenesis, so as to provide a better choice for the treatment of BPD and ROP and improve the effectiveness of the treatment effect.
