Abstract
Posterior retinopathy of prematurity (ROP) is unusual in its atypical features and its aggressive, rapidly progressive course. It is more difficult to recognize and to treat, with many of these eyes progressing to retinal detachment despite multiple treatments with laser or cryotherapy. The authors present a case of aggressive posterior ROP refractory to multiple laser treatment. This patient was successfully treated with intravitreal bevacizumab, but required repeat treatment 4 months later. The second injection with bevacizumab was followed by progression to retinal detachment requiring surgery. The patient remains stable after surgery.
