In Beijing, rates of ROP needing treatment are high, and affected babies are more mature than in NICUs in high-income countries. More needs to be done to prevent ROP through improved neonatal care.

MHCI could be an easily measured and accurate predictive index for postoperative anatomical outcomes.

In patients with idiopathic full-thickness macular hole and MHCI ≤0.5, a larger ILM peel of 4DD tends to achieve better anatomical outcomes than a more limited 2DD peel.

Purpose To compare the effectiveness of intravitreal conbercept and ranibizumab treatment for retinopathy of prematurity (ROP). Methods In this retrospective study, the date of patients with ROP treated with intravitreal conbercept or ranibizumab from July 2012 to March 2018 with at least 12 months of follow‐up at the Eye Center in People’s Hospital of Peking University were analysed. Regression, progression or recurrence and peripheral retina vascularization were evaluated. Results In total, 283 eyes (145 infants) with conbercept treatment and 916 eyes (480 infants) with ranibizumab treatment were enrolled. In zone I ROP and aggressive posterior ROP (APROP), the recurrence prevalence was 49.09% (108/220 eyes) and 28.57% (10/33 eyes), and the recurrence interval was 7.87 ± 0.65 (5.5–9.5) weeks and 10.6 ± 1.53 (10.5–13) weeks in the ranibizumab and conbercept groups, respectively. In zone II ROP disease, the recurrence prevalence was 23.56% (164/696 eyes) and 13.31% (33/248 eyes), and the interval of recurrence was 8.40 ± 0.88 (6–10.5) weeks and 11.4 ± 1.35 (11–13.5) weeks in the ranibizumab and conbercept groups, respectively. The recurrence prevalence was significantly higher with ranibizumab in Zone I ROP and APROP (p = 0.006) and Zone II ROP (p < 0.001), and the recurrence interval was significantly longer in the conbercept group than that in the ranibizumab (p < 0.001). There was no significant difference in the rate of retinal vascularization (p = 0.441). Conclusion Conbercept and ranibizumab are effective for treating ROP. Compared with ranibizumab, conbercept resulted in less recurrence and longer treatment intervals.

Intravitreal Conbercept (IVC) is the latest applied and effective treatment for the management of retinopathy of prematurity (ROP). However, conbercept escapes from the vitreous into the general circulation and reduce systemic VEGF concentrations. Thus, there are concerns about systemic complications, in these premature infants who are developing vital organ systems. This study is to determine whether a low dosage (0.15 mg/0.015 mL) of IVC is effective in the treatment of Zone II Stage 2/3 + ROP. A total of 38 eyes of 20 infants were analyzed retrospectively. We identified treatment effectiveness as complete regression of retinopathy and retinal vascularisation to zone III. The mean gestational age (GA), postmenstrual age (PMA) at treatment and birth weights (BW) were 28.6 ± 2.2 weeks, 39.3 ± 3.0 weeks and 1297.5 ± 429.2 g respectively. Primary effectiveness (react to IVC 0.15 mg alone) was found in 32/38 eyes (84.2%). Secondary effectiveness (a second IVC was required) was found in 6/38 eyes (15.8%). Follow-up continued until 90 weeks’ postmenstrual age and showed no recurrences of plus disease or neovascularization. The study suggests 0.15 mg IVC is effective for Zone II Stage 2/3 + ROP, and there is no adverse ocular outcomes during the follow-up period.
