				        	Objective To observe the effect ofintravitreal injection ofconbercept in the treatment of retinopathy of premature (ROP) and to analyze the factors related to the therapy.Methods A retrospective study.A total of 57 patients (57 eyes) with pre-threshold type 1 (30 patients,30 eyes),threshold ROP (21 patients,21 eyes) and acute aggressive posterior ROP (APROP,6 patients,6 eyes)) from premature infants by retinal screening in Henan Provincial People's Hospital during October 2017 and June 2018 were enrolled in this study.All children were received routinely intravitreal injected 10 mg/ml conbercept 0.025 ml (0.25 mg) within 24 hours after diagnosis.Fundus examination was performed 7 days after injection.The interval of examination was 1-3 weeks according to fundus conditions.The mean follow-up was 30.1 ± 4.6 weeks.For patients with relapse or no response to treatment,repeated intravitreal injection of conbercept or laser photocoagulation therapy was given.The retinal blood vessels of the affected eyes were observed.Logistic stepwise regression analysis was used for the correlation test of multiple factors.Results Among 57 eyes,49eyes and 8 eyes were treated with 1 or 2 times of intravitreal injection of conbercept.After 24 weeks of treatment,in 57 eyes,26 eyes were cured (45.6%),22 eyes improved (38.6%),8 eyes relapsed (14.0%),and 1 eye aggravated (1.8%).The recurrence time was 12.9± 4.5 weeks after the first injection,and the corrected gestational age was 49.0±6.7 weeks.There were significant differences in initial injection time,lesion range among the cure,improved and recurrence eyes (F=5.124,7.122;P<0.01,< 0.01).Parameters of ROP condition,including ROP diagnosis (pre-threshold type 1,threshold and APROP),zone (zone 1 and 2),stage (stage 2 and 3) and plus lesions,were significant different among the cure,improved and recurrence eyes (x2=l 1.784,14.100,6.896,9.935;P<0.01,<0.01,<0.05,<0.01).Logistic stepwise regression analysis showed that the recurrence rate was correlated with ROP zone,more likely recurrence at zone 1 than zone 2 (Wald=9.879,OR=27.333,P=0.002).No injection-related complications such as endophthalmitis,cataract and glaucoma were found during treatment and follow-up period.Conclusions Intravitreal injection ofconbercept is effective in the treatment of ROP without obvious adverse reactions.Lesion zoning is associated with recurrence after treatment.
