PURPOSE: To determine if fluorescein angiographic (FA) findings after intravitreal ranibizumab (IVR) for retinopathy of prematurity (ROP) conform to a class effect previously described with bevacizumab.
METHODS: Single-center retrospective case series of all infants treated with 0.2 mg (0.02 mL) IVR for Type 1 ROP from July 2016 to November 2018. FA were obtained at 40, 52, 62, and 72 weeks of postmenstrual age (PMA) using wide-angle photography. FA images were analyzed and the peripheral avascular areas measured with ImageJ using a reference disc diameter (DD). Based on the extent of the avascular area and tortuosity of the retinal vessels all eyes were classified into four categories: complete vascular maturity (vascularization within 2 DD of the ora serrata), VAA (avascular area >2 DD of the ora serrata), VAT (avascular area >2 DD of the ora serrata and posterior tortuosity), and reactivation (recurrence of stage disease).
RESULTS: About 13 infants were enrolled and 24 eyes were available in this study. None of the eyes reached complete vascular maturity at an average PMA of 60 weeks, 7 (29%) eyes presented with VAA, 8 (33%) with VAT, and 9 (37.5%) reactivated. The reactivated eyes presented with the largest area of peripheral ischemia, followed by the VAT and then the VAA groups (p = 0.02).
CONCLUSION: IVR conforms to the previously described regression patterns following intravitreal bevacizumab for ROP indicative of a class effect. Follow-up using FA might help to optimize the management of these infants after injection of the drug.
