AIM: To analyze the occurrence and influencing factors of retinopathy in prematurity.

METHODS: Totally, 103 premature infants born in Ningbo Women and Children's Hospital Department of Ophthalmology from May 2012 to May 2013 were selected as the research objects. The incidence and risk factors of screening for ROP were checked.

RESULTS: The positive rate of preterm infants was 11.7%. Logistic multivariate regression analysis results showed that the gestational age, birth weight, oxygen concentration, mechanical ventilation, oxygen time, anemia, intracranial hemorrhage were the risk factors of ROP(P<0.05).

CONCLUSION: Low birth weight of premature infants and oxygen concentration factors has significant relationship with the occurrence of ROP.
