Abstract

Purpose:To evaluate angiographic findings in neonates up to 150 weeks postmenstrual age who received intravitreal ranibizumab for primary treatment of Type 1 retinopathy of prematurity.Methods:Retrospective evaluation of fluorescein angiogram findings was completed for 30 eyes of 16 neonates who received intravitreal ranibizumab as primary treatment for Type 1 retinopathy of prematurity between April 2013 and January 2015. Outcome measures included maturity to Zone III, vascular blunting, vascular loops, vascular dilatation, capillary dropout, and vascular fluorescein leakage.Results:Mean gestational age was 241/7 weeks and mean postmenstrual age at time of intravitreal ranibizumab treatment was 35 weeks. Fluorescein angiograms performed at 44 weeks to 150 weeks postmenstrual age showed only 50% of eyes reached vascularization to Zone III; 40% had persistent vascular leakage; and ≥90% exhibited vascular blunting, vascular dilatation, and/or capillary dropout.Conclusion:Although intravitreal ranibizumab is effective in initial cessation of Type 1 retinopathy of prematurity, vascularization to Zone III was only achieved in 50% of eyes in our series and most eyes had fluorescein angiography evidence of vascular anomalies. If future studies are performed comparing treatment with laser photocoagulation to anti-vascular endothelial growth factor, fluorescein angiographic studies should be considered to assess the status of the peripheral retinal vasculature to determine treatment effect.
