Purpose The aim of the study was to evaluate the outcomes of intravitreal bevacizumab (IVB) monotherapy compared with conventional laser therapy in preterm infants with stage III and plus disease retinopathy of prematurity (ROP) who had zone I or II posterior disease. Patients and methods This was a prospective randomized comparative interventional pilot study. Twenty-four eyes of 12 preterm infants suffering from ROP were included. All eyes had bilateral stage III ROP with 'plus disease' affecting zone I or zone II posterior. Infants were assigned to receive conventional laser therapy in their right eyes and IVB in their left eyes. Follow-up period was 6 months following treatment. Results The study included five female infants and seven male infants. The gestational ages ranged from 26 to 33 weeks (mean 29 weeks), and the birth weights ranged from 750 to 1390 g (mean 1005 g). The postmenstrual age at which threshold ROP was detected ranged between 34 and 41 weeks (mean 36.75 weeks). All 24 eyes had stage III ROP with plus disease; 10 eyes had zone I, whereas the other 14 eyes had zone II posterior. Regression of neovascularization occurred in all 24 eyes following both treatment modalities and remained stable during follow-up. No local or systemic side effects of bevacizumab were observed, and no further treatment was necessary. Conclusion IVB injection seems to be as effective as conventional laser in treating stage III ROP. It provides the advantages of preservation of peripheral visual field and complete peripheral retinal vascularization.
