Asymmetric Outcomes of Type 1 Retinopathy of Prematurity after Bilateral Intravitreal Ranibizumab Treatment

Figure 1

Before treatment, both eyes were diagnosed as stage 3+ ROP in zone I ((a) and (b)). Ten days after IVR, the right eye revealed regression (c), but the left eye revealed stage 5 ROP with marked posterior fibrosis and vitreous hemorrhages (VH) (d). The right eye received laser treatment at 43 weeks PMA, and the retina was flat at the last follow-up (e). The left eye received a lensectomy and vitrectomy at 57 weeks PMA, and the retina was not reattached at the last follow-up (f).
