方法：选取2012-05/2013-05间在我院眼科出生的103例早产儿作为研究对象，筛查早产儿视网膜病变发生率及影响因素。

结果：早产儿视网膜病变检出率为11.7%，多因素Logistic回归分析显示胎龄、吸氧浓度、出生体质量、机械通气、吸氧时间、贫血、颅内出血均为早产儿视网膜病变的危险因素(P<0.05)。

结论：低出生体质量的早产儿在吸氧浓度等因素上都与早产儿视网膜病变的发生有显著关系。

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.
