目的 分析未成熟儿视网膜病变 (retinopathyofprematurity ,ROP)的危险因素。 方法 对 1 3 2例 (2 64眼 )早产儿 (孕周 <3 7周 ,出生体重 <2 5 0 0 g) ,自出生后第 1周开始行眼底检查 ,根据ROP国际分期法进行诊断并分期 ,观察孕周、出生体重和供氧浓度等因素对ROP的影响 ,并随访半年。结果 1 3 2例早产儿中患有不同程度ROP者 3 1例 ,ROP发生率为 2 3 5 % ;且孕周越短、出生体重越轻、供氧浓度越高 ,ROP发生率越高。结论 必须对有吸氧史的早产儿常规进行眼底检查。
Objective To analyze the risk factors of retinopathy of prematurity (ROP). Methods One hundred and two cases (264 eyes) of preterm infants (gestational week <37 weeks, birth weight <2500 g) were examined by fundus examination at the first week after birth and diagnosed according to the ROP international staging method Staging, observing gestational age, birth weight and oxygen concentration and other factors on the ROP, and follow-up for six months. Results 31 cases of premature infants with different degrees of ROP in 31 cases, the incidence of ROP was 23.5%; and shorter gestational age, birth weight lighter, the higher the oxygen concentration, the higher the incidence of ROP. Conclusions Fundus examination should be routinely performed on preterm infants with a history of oxygen inhalation.
