Kimyon S, et al. - Authors gauged the impacts of bevacizumab and ranibizumab in the treatment of type 1 retinopathy of prematurity (ROP) affecting zone 1. In the treatment of type 1 ROP affecting zone 1, similar effectiveness of bevacizumab and ranibizumab was noted. As per data, in eyes treated with intravitreal bevacizumab (IVB) AXL was longer and spherical equivalent (SE) was more myopic. Compared to ranibizumab, the longer intravitreal half-life could cause this difference.
