To compare the results of ranibizumab and aflibercept treatment in infants with treatment-requiring retinopathy of prematurity (ROP) in the posterior zone.
In this single-center, retrospective study, the records of the infants, who were treated between January 2015 and June 2017 in a tertiary center for screening and treatment of ROP, were reviewed. Infants who were administered ranibizumab or aflibercept as initial treatment and completed at least 1 year of corrected age were included. The patients were evaluated in terms of regression, progression or recurrence of the disease, vascularization of the peripheral retina, and ocular complication profile in early or late period.
Fifty-four eyes of 27 infants who received ranibizumab treatment (ranibizumab group) and 72 eyes of 36 infants who received aflibercept treatment (aflibercept group) were enrolled. The rate of recurrence was 48.1% in ranibizumab group and 13.9% in aflibercept group. The mean recurrence times were at 8.2 ± 0.92 weeks following the injection of ranibizumab and at 14.2 ± 1.03 weeks following the injection of aflibercept. There were significant statistical differences between the groups in the rate of ROP recurrence, the time of recurrence, and the time of vascularization of peripheral retina (p = 0.001, p < 0.001, p < 0.001, respectively).
Although both ranibizumab and aflibercept are effective therapies for the treatment of ROP, more frequent and much earlier recurrences can be seen with ranibizumab treatment. Further studies are needed to obtain ideal options for the treatment of ROP.
