Intravitreal bevacizumab for retinopathy of prematurity as first line or rescue therapy with focal laser treatment. A case series.

OBJECTIVES Laser therapy is effective in the treatment of severe forms of retinopathy of prematurity (ROP), and aggressive posterior ROP (APROP), but always damages the retina. We report our preliminary findings in seven premature infants with complicated ROP or APROP who were treated with intravitreal bevacizumab (IVB) as first line monotherapy or rescue therapy combined with laser treatment. METHODS We studied retrospectively seven preterm infants, who were affected by APROP (n = 4) or pre-threshold ROP (n = 3). Infants were treated with IVB (0.625 mg; Avastin®, Roche, Basel, Switzerland) monotherapy (n = 2) when they were too sick to undergo lengthy laser treatment. RESULTS Monotherapy IVB (n = 3 eyes) and IVB combined with laser therapy (n = 3 eyes) of APROP cases were followed by regression of the ROP and complete peripheral vascularization. The combined therapy with IVB and laser therapy of pre-threshold ROP (5 eyes) produced a regression of neovascularization and good retinal anatomical outcome. CONCLUSIONS In our series, IVB was successful in treating ROP in a small cohort of extremely preterm infants with APROP or pre-threshold ROP, both as monotherapy or rescue treatment after laser therapy, without the development of ocular and systemic short- and long-term adverse effects.
