To report a retrospective, consecutive, noncomparative case series of moderate and severe stage 3 retinopathy of prematurity (ROP) in zone I or posterior zone II treated by bilateral intravitreal injections of bevacizumab (Avastin; Genentech, Inc., South San Francisco, CA).Methods:
Eleven infants weighing from 515 g to 1,015 g at birth (mean, 706.4 g) with gestational ages from 23 weeks to 28 weeks (mean, 24.3 weeks) received intravitreal injections of bevacizumab (0.625 mg [0.025 mL]) at 9.0 weeks to 15.0 weeks of age (mean, 11.0 weeks) and never had laser therapy. Length of follow-up was from 13.0 weeks to 85.0 weeks (mean, 48.5 weeks). RetCam photography (Clarity Medical Systems, Pleasanton, CA) was used to document preinjection retinal appearance and to follow postinjection retinal appearance.Results:
All 22 eyes were treated successfully (no retinal detachment, macular ectopia, high myopia, anisometropia, or other ocular abnormalities) with only 1 injection. No complications (local or systemic) were encountered.Conclusions:
Intravitreal injection of bevacizumab was safe and effective in treating stage 3 ROP in zone I and posterior zone II in this small series of patients. A prospective, randomized, controlled, multicenter clinical trial has been initiated to investigate further this promising treatment.
