Abstract:
Objective To observe the clinical effects of anti-vascular endothelial growth factor (VEGF) agent for retinopathy of prematurity (ROP) in different zones.Methods Retrospective analysis was performed on 24 ROP patients (46 eyes) who received intravitreal injection of anti-VEGF agent in our hospital from April 2013 to April 2014,including 15 patients (28 eyes) with Zone Ⅰ ROP and 9 patients (18 eyes) with Zone Ⅱ ROP.All the patients receive intravitreal injection of anti-VEGF agent Ranibizumab.The patients were observed for postoperative progression of fundus conditions,and the recovery rate and progression rate following initial injection were compared statistically between two groups.Results There was no statistically significant difference between the two groups in gestational age at birth or birth weight (both P ＞0.05);And statistically significant difference was found between two groups in gestational age at surgical correction (P =0.001).Following initial injection,the recovery rates were 32.14％ and 66.67％,and the progression rates were 67.86％ and 33.34％ in Zone Ⅰ ROP group and Zone Ⅱ ROP group,respectively,there was statistically significant difference between the two groups in recovery rate (x2 =5.263,P =0.022).The progression rate in Zone Ⅰ ROP group was higher than that in Zone Ⅱ ROP group,there was statistically significant difference (x2 =-2.269,P =0.023).During follow-up,no complications of intravitreal injection as cataract,endophthalmitis or retinal tears was observed;Only 2 patients experienced corneal edema,and 4 patients experienced subconjunctival hemorrhage.Conclusion Intravitreal injection of anti-VEGF agent is effective for both Zone Ⅰ and Zone Ⅱ ROP.While for Zone Ⅰ ROP,the surgery success rate is low and the reoperation rate is high,such treatment can provide favorable time and conditions for reoperation.
