Bevacizumab compared with diode laser in stage 3 posterior retinopathy of prematurity: A 5 year follow up.

We conducted a prospective randomized study to compare outcomes of intravitreal Bevacizumab versus diode laser in thirty eyes of fifteen premature babies with zone 1 or posterior zone 2 retinopathy of prematurity (ROP). We recorded complications, regression/reactivation of ROP, visual outcome, refractive error and systemic complications. The Bevacizumab treated eyes showed rapid regression of the ROP with resolution of plus disease and flattening of the ridge at 48 hours post injection. In 3 Bevacizumab treated eyes, reactivation occurred and were treated with laser (3 eyes) or a further Bevacizumab injection (1 eye). Of the diode laser treated eyes, one showed progression and was treated with Bevacizumab. At 5 year follow up, good outcomes were observed in both treatment groups. Hoever, less myopia was found in the Bevacizumab compared with the diode laser treated eyes.
