目的：评价玻璃体内注射康柏西普在治疗I型(阈值期和阈值前期)和A-ROP(急进性ROP)的早产儿视网膜病变(ROP)的一系列病例中引起的视网膜血管化过程。方法：回顾性研究2017-07/2020-03在厦门市儿童医院眼科通过玻璃体腔注射康柏西普(IVC)治疗的ROP患者34例67眼。再活化是指急性期特征的复发，发生在疾病的任何阶段，无论是否存在其他疾病。结果：患儿34例的平均胎龄为28.82±2.32wk。平均出生体质量为1155.18±398.22g。19例37眼的病变区域为Ⅰ区。10例20眼的病变位于Ⅱ区，5例10眼的病变位于Ⅱ区后部。一次IVC治疗的ROP患儿疾病控制总有效率为73.1%(49/67)，且Ⅱ区血管化均完成。患者在Ⅲ区的血管化完成率出现差异。在接受过一次治疗且未再复发的患者中，Ⅰ型ROP血管化时间平均为9.11±2.49wk，A-ROP为13.40±4.04wk。A-ROP的血管化完成时间明显比Ⅰ型ROP的时间长，且结果有统计学差异。结论：IVC治疗后的病变为Ⅱ区的患儿均具有较高的血管完成率。

AIM: To evaluate retinal vascularization caused by the intravitreal injection of Conbercept in the treatment of a series of retinopathy of prematurity(ROP)cases in Type Ⅰ(threshold and pre-threshold period)and aggressive ROP(A-ROP).METHODS: The data of 34 ROP cases(67 eyes)treated by intravitreal injection of Conbercept(IVC)in the ophthalmology department of the Xiamen Children's Hospital from July 2017 to March 2020 were retrospectively analyzed. Reactivation, which refers to recurrence of acute phase features, occurred at any stage of the disease in the presence or absence of other diseases. RESULT: The average gestational age of the 34 children was 28.82±2.32wk. The average birth weight was 1155.18±398.22g. The lesion zone of 19 cases(37 eyes)was Zone Ⅰ. In 10 cases(20 eyes), the lesion was in Zone Ⅱ, and in 5 cases(10 eyes), the lesion was in the posterior Zone Ⅱ. The total effective rate of disease control in ROP children treated with once IVC was 73.1%(49/67), and the vascularization of Zone Ⅱ was completed. The patients showed variable changes in the vascularization in Zone Ⅲ. For the patients who received one treatment and did not reactivate, the average rate of Type Ⅰ vascularization of ROP was 9.11±2.49wk, and the A-ROP was 13.40±4.04wk. The rate of A-ROP vascularization in Zone Ⅱ was significantly longer compared to Type Ⅰ.CONCLUSION: IVC effectively completes vascularization in Zone Ⅱ.
