Objectives The objective of this study is to evaluate the progression and new onset of macular retinoschisis (MRS) in the patients treated with intravitreal Conbercept injections for myopic choroidal neovascularization (mCNV). Methods Post-hoc analysis of 160 mCNV patients included in SHINY study was performed to evaluate the impact of Conbercept injection on MRS in patients with mCNV undergoing intravitreal Conbercept injections. The patients were 3:1 randomized to the study group (three loading dose and thereafter pro re nata [PRN]) and the control group (3 months’ sham injection, then one Conbercept injection at month 4 and thereafter PRN). MRS was assessed with optical coherence tomography by masked graders. Results At baseline, 28 of 122 eyes in study group and 10 of 38 eyes in control group had MRS. At month 3, two patients showed MRS progression and one patient had new onset MRS in study group. No MRS progression nor new onset MRS was found in the control group. At final visit, the cumulative incidence of MRS was 1.3% (2/160). Both Spearman’s correlation and multiple logistic regression demonstrated no association between the progression and new onset of MRS and intravitreal injection frequency (correlation coefficient = 0.017, P = 0.851 and odds ratio = 0.996, P = 0.982). In addition, baseline vitreoretinal adhesion was the most likely potential risk factor resulting in MRS progression (odds ratio = 4.566, P = 0.027). Furthermore, MRS progression was more likely to take place in outer retinal layers. Conclusions The progression and new onset of MRS was not associated with the frequency of intravitreal Conbercept injections.

康柏西普治疗后近视脉络膜新生血管眼黄斑部视网膜劈裂的进展和新发:事后分析

目的 本研究的目的是评估接受玻璃体内康柏西普注射治疗近视脉络膜新生血管 (mCNV) 的患者中黄斑视网膜劈裂 (MRS) 的进展和新发。方法 对 SHINY 研究中包括的 160 名 mCNV 患者进行事后分析,以评估康柏西普注射液对接受玻璃体内注射康柏西普的 mCNV 患者 MRS 的影响。将患者按 3:1 随机分配到研究组(3 次负荷剂量,然后是 pro re nata [PRN])和对照组(3 个月假注射,然后在第 4 个月注射 1 次康柏西普,然后是 PRN)。MRS 由蒙面分级师使用光学相干断层扫描进行评估。结果在基线时,研究组122只眼中的28只眼和对照组38只眼中的10只眼有MRS。在第 3 个月,研究组有 2 名患者出现 MRS 进展,1 名患者出现新发 MRS。在对照组中未发现 MRS 进展或新发 MRS。最后一次就诊时,MRS 的累积发生率为 1.3% (2/160)。Spearman 相关性和多元逻辑回归均表明 MRS 的进展和新发与玻璃体内注射频率之间没有关联(相关系数 = 0.017,P = 0.851 和优势比 = 0.996,P = 0.982)。此外,基线玻璃体视网膜粘连是最可能导致 MRS 进展的潜在风险因素(优势比 = 4.566,P = 0.027)。此外,MRS 进展更可能发生在视网膜外层。结论 MRS 的进展和新发与玻璃体内康柏西普注射的频率无关。
