%X To investigate biometric and refractive results in patients with type 1 retinopathy of prematurity (ROP) treated by intravitreal injection (IVI) of ranibizumab (R) and bevacizumab (B) at the corrected age of 6. This is a single-center retrospective study. Infants diagnosed with type 1 ROP and treated with IVI of either R or B as the primary therapy were included. Data on axial length, anterior chamber depth (ACD), and lens thickness (LT) were obtained using A-scan ultrasound. Cycloplegic refraction, keratometry (K), and best-corrected visual acuity were also documented. Additionally, optical coherence tomography angiography was performed to assess the foveal avascular zone and the density of superficial and deep vessels. We analyzed the structural and functional differences between the 2 groups and compared them with findings from a previous study conducted when these children were between the ages of 1 and 3. The study included 60 eyes from 34 patients, with 34 eyes receiving B and 26 eyes receiving R injections for ROP. In biometric outcomes, there was still a deeper ACD (3.36 ± 0.24 mm in the B group; 3.52 ± 0.21 mm in the R group) and thinner LT (3.63 ± 0.16 mm in the B group; 3.53 ± 0.12 mm in the R group) in the R group, as previously reported at the age of 3. In the refractive aspect, the eyes treated with B had higher myopia at the ages of 1 and 3; however, at the age of 6, refractive errors did not differ significantly between the 2 groups. At the corrected age of 6, the eyes treated with IVI of R were associated with deeper ACD and thinner LT. Interestingly, the emmetropization process resulted in a similar incidence of high myopia at the age of 6, which was different from the outcomes observed at younger ages.
