Treatment for Nontype 1 Retinopathy of Prematurity by Intravitreal Injection of Antivascular Endothelial Growth Factor Drugs

Figure 1

Nontype 1 ROP eyes considered to be treated due to multiple reasons. Case no. 3, male, GA 30 w, BW 1.3 kg. ROP in zone II, stage 2 with plus (−) in both the eyes was transferred to examination in PMA 39.1w (a, b). After 2 weeks (PMA 41.1w), the temporal ridge was thickened and widened with preplus in the right eye, which was ROP in zone II, stage 3 with preplus (c). As the contralateral eye, the ridge was more obvious and extended, which was still ROP in zone II, stage 2 with plus (−) (d). The bilateral retinal vessels grew to the periphery of zone III at 27.9 weeks (PMA 69.0w) after intravitreal injection of conbercept (e, f).
