title: Intravitreal Bevacizumab in Retinopathy of Prematurity: Inject or Not?
abstract: This article is aimed to review and summarize the indications, outcomes and safety profiles regarding the use of intravitreal bevacizumab in patients with retinopathy of prematurity (ROP) as reported in previous studies with no intention to compare the efficacy between intravitreal bevacizumab and laser photocoagulation.Literature search was conducted in databases such as PubMed, Cochrane, Ovid, and Ophthalmology Advance using the terms "ROP," "antiangiogenic," "antivascular endothelial growth factor," "intravitreal bevacizumab," and "Avastin."Eight prospective studies of 278 eyes of ROP infants and 15 retrospective studies involving 385 eyes of ROP infants treated with intravitreal bevacizumab were found. Bevacizumab was used as monotherapy, adjunctive therapy, and/or combined therapy.The varied use of intravitreal bevacizumab in treating ROP and he limited number of landmark studies contribute to the difficulties in drawing a strong conclusion in this review. Intravitreal bevacizumab was more commonly injected in: (1) type 1 ROP zone I and/or posterior zone II; (2) aggressive posterior ROP with poor retinal visualization in which laser photocoagulation would be difficult to perform; and (3) stage 4 ROP before vitrectomy. All cases demonstrated regression of neovascular activity during a varied follow-up period (from 1 week to 1 month) after injection. However, recurrence may occur. Follow-up until 80 weeks of postmenstrual age is thus recommended. Acceleration of fibrous traction is the most common ocular adverse effect after injection, whereas the systemic adverse effect remains uncertain. Landmark studies of the efficacy of intravitreal bevacizumab injection in treating ROP are warranted.
