Purpose
To compare type I retinopathy of prematurity (ROP) with aggressive posterior retinopathy of prematurity (AP-ROP) regarding risk factors, complications and treatment outcomes.
Methods
A prospective cohort approach was applied on premature newborns diagnosed as type I ROP and AP-ROP. An intravitreal injection of bevacizumab (Avastin®) was given to each patient. Demographic features such as gestational age, birth weight, age at the initial injection, involved eye, treatment response, relapses and need to extra interventions were compared.
Results
Seventy-seven patients underwent an initial intravitreal injection of bevacizumab (IVB), and 108 eyes were type I ROP and 30 eyes were AP-ROP. There was no significant difference in birth weight and gestational age between two groups. ROP relapsed in eight eyes of four patients with AP-ROP (26.6%), of which six eyes of three patients received re-injection of bevacizumab, and two eyes of one patient underwent a laser treatment. Recurrence occurred in two eyes of one patient with type I ROP (1.8%), which were treated by laser.
Conclusion
Bilateral eye involvement, relapse and retreatment (IVB, laser and surgical intervention) are more frequent in AP-ROP than type I ROP even when treated with intravitreal bevacizumab injection.
