PURPOSE: To investigate the anatomic outcomes and influencing factors of ranibizumab in the treatment of retinopathy of prematurity (ROP).
DESIGN: Retrospective case series.
PARTICIPANTS: A total of 283 eyes of 145 patients with type 1 ROP treated with intravitreal injection of ranibizumab (IVR) as primary treatment.
METHODS: Retrospective review of infants who were diagnosed with type 1 ROP and accepted IVR (0.25 mg/0.025 ml) as primary treatment from January 2012 to August 2015. The anatomic outcomes and the influencing factors were analyzed.
MAIN OUTCOME MEASURES: Anatomic outcomes of ROP eyes after IVR and the influencing factors.
RESULTS: A total of 283 eyes of 145 patients were included in this study. There were a total of 266 eyes (94.0%) in the positive response group and 17 eyes (6.0%) in the negative/no response group after IVR. Within the positive response group, 139 eyes (48.6%) were in the regression without reactivation subgroup, and 127 eyes (44.9%) were in the regression with reactivation subgroup. A total of 152 eyes received additional laser or surgical treatment. At the last visit, 278 eyes (98.2%) had attached retinas, and 5 eyes (1.8%) had retinal detachment. A classification tree model showed that for patients with gestational age (GA) ≤29.5 weeks, the possibility of experiencing reactivation after IVR is higher than that of those with GA >29.5 weeks (61.6% vs. 29.6%). Moreover, for patients with GA ≤29.5 weeks, those diagnosed with zone II stage 2+ ROP have a lower possibility of experiencing reactivation than other patients (37.9% vs. 80%).
CONCLUSIONS: Intravitreal injection of ranibizumab seemed to be effective in treating patients with ROP. After treatment, there were primarily 3 different outcomes. Our predictive tree model is helpful for ophthalmologists to evaluate the risk of reactivation.
