Background/Aims Early detection and timely treatment of type 1 retinopathy of prematurity (ROP) can reduce the risk of blindness. To evaluate the incidence, timing and risk factors of type 1 ROP in a large, broad-risk cohort of premature infants. Methods Secondary analysis of data from the two Postnatal Growth and Retinopathy of Prematurity studies. Main outcomes are the incidence and timing of type 1 ROP. Results Among 11 463 infants (mean birth weight (BW), 1095 g; mean gestational age (GA), 28 weeks), 677 (5.9%, 95% CI 5.5% to 6.3%) developed type 1 ROP. Rate of type 1 ROP decreased with larger GA (28.8% for GA ≤23 weeks, 0.2% for GA of 31–32 weeks) and no infants with GA >32 weeks developed type 1 ROP. Type 1 ROP was first diagnosed at a median postmenstrual age (PMA) of 36 weeks (range 30–46 weeks) or postnatal age (PNA) of 11 weeks (range 5–21 weeks). The mean PMA at diagnosis of type 1 ROP increased with GA (35 weeks for GA of 22–24 weeks, 41 weeks for GA of 29–30 weeks), but the mean PNA at diagnosis of type 1 ROP was similar (11–13 weeks) across GA of 22–29 weeks. GA and BW dominate the association (area under the receiver operating characteristic curve=0.87, 95% CI 0.86 to 0.88). Conclusions Type 1 ROP developed in about 6% of premature infants over wide time windows in terms of both PMA and PNA. BW and GA are the dominant risk factors for type 1 ROP, while other prenatal factors add minimal predictive power for type 1 ROP.

北美队列中 1 型早产儿视网膜病变的发病率、发生时间和危险因素



背景/目标 早期发现并及时治疗 1 型早产儿视网膜病变 (ROP) 可降低失明风险。旨在评估大型、广泛风险的早产儿队列中 1 型 ROP 的发生率、发生时间和危险因素。方法 对两项产后生长和早产儿视网膜病变研究的数据进行二次分析。主要结果是 1 型 ROP 的发生率和发生时间。结果 在 11 463 名婴儿(平均出生体重 (BW),1095 g;平均胎龄 (GA),28 周)中,677 名(5.9%,95% CI 5.5% 至 6.3%)出现 1 型 ROP。 1 型 ROP 的发生率随着 GA 的增加而降低(GA ≤ 23 周为 28.8%,31-32 周为 0.2%),并且 GA >32 周的婴儿没有发生 1 型 ROP。 1 型 ROP 首次诊断时中位经后年龄 (PMA) 36 周(范围 30-46 周)或产后年龄 (PNA) 11 周(范围 5-21 周)。诊断 1 型 ROP 时的平均 PMA 随 GA 的增加而增加(22-24 周的 GA 为 35 周,29-30 周的 GA 为 41 周),但诊断 1 型 ROP 时的平均 PNA 相似(11-13周),整个 GA 为期 22-29 周。 GA 和 BW 在关联中占主导地位(受试者工作特征曲线下面积=0.87,95% CI 0.86 至 0.88)。结论 就 PMA 和 PNA 而言,在很长的时间范围内,约 6% 的早产儿发生 1 型 ROP。 BW 和 GA 是 1 型 ROP 的主要危险因素,而其他产前因素对 1 型 ROP 的预测作用微乎其微。
