Retinal blood flow velocities in infants with retinopathy of prematurity after intravitreal administration of bevacizumab.

Background/objectives: Progression of retinopathy of prematurity (ROP) is associated with increased retinal blood flow velocities. We investigated changes of central retinal arterial and venous blood flow after intravitreal administration of bevacizumab.

Subjects/methods: Prospective observational study using serial ultrasound Doppler imaging in preterm infants with bevacizumab-treated ROP.
