Quantitative comparison of blood vessel changes after treatment of retinopathy of prematurity with laser versus bevacizumab.
Current therapies for treatment-indicated (type 1) retinopathy of prematurity mainly consist of laser photocoagulation and intravitreal anti-vascular endothelial growth factor (eg, bevacizumab) injection. The first visible signs of acute-phase regression are typically vascular, including decreased plus disease. Using a semiautomated computer program, we quantitatively compared posterior pole vascular changes following treatment with laser versus bevacizumab and found that in the first month following treatment, vascular dilation and tortuosity significantly decreased following either treatment modality, but tortuosity decreased earlier and faster after bevacizumab.
