Abstract:
Objective To observe the efficacy and safety of intravitreal injection of ranibizumab in the treatment of retinopathy of prematurity (ROP).Methods Data from 49 consecutive ROP patients (95 eyes) including type Ⅰ pre-threshold,threshold and aggressive posterior ROP who had received anti-VEGF treatment for the first time in our hospital from June 2014 to August 2015 were collected.60 eyes from the 95 eyes were confined as the zone Ⅰ disease group,while the remaining 35 eyes as zone Ⅱ disease group.The difference of birth weight,gestational age,corrected gestational age,treatment effects,recurrence and re-treatment time between two groups were compared.0.025 mL ranibizumab (10 mg · mL-1) was injected through 1.5 mm puncture after corneal limbus by using 30G 1 mL injection syringe.At the end of the injection,tobramycin and dexamethasone ophthalmic ointment eye bag was used.After the injection of 3 days,the portable slit lamp and tonometer were used to observe the intraocular pressure,intraocular hemorrhage and endophthalmitis.The indirect ophthalmoscope was used to observe the retinal vascular tortuosity and ridge regression of lesion expansion at 1 week after treatment.At the same time,the systemic adverse reactions related to treatment were observed.Results After receiving ranibizumab treatment for the first time,93 eyes (95.9％) exhibited ROP regression after single injection,including 58 eyes in zone Ⅰ disease group,35 eyes in zone Ⅱ disease group.There was no statistical difference between two groups (P ＞ 0.05).22 eyes required additional anti-VEGF injection or laser treatment for ROP recurrence,including 17 eyes in zone Ⅰ disease group,5 eyes in zone Ⅱ disease group.There was statistical difference between two groups (P ＜0.05).The time from recurrence to re-treatment was (6.50 ±2.54) weeks,which in zone Ⅰ disease group was (6.44 ± 2.74) weeks and in zone Ⅱ disease group was (6.67 ± 2.31)weeks,there was no statistical difference between two groups (P ＞ 0.05).No local or systemic adverse events associated with the treatment or drug was observed within the following period.Conclusion Intravitreal injection of ranibizumab is an effective and well tolerated method for zone Ⅰ and zone Ⅱ ROP,but the recurrence rate is high.There Is no local or systemic adverse events associated with the treatment or drug.
