Purpose

To report distinct structural changes following surgery for myopic traction maculopathy (MTM).

Study design

A single-center, retrospective case series.

Methods

Patients with MTM who underwent vitrectomy and had persistent large intraretinal cavities and schisis were reviewed. The pre- and postoperative clinical findings and optical coherence tomography characteristics are described.

Results

Five eyes of five patients were included in the study. Three patients had prominent schisis, and four had retinal/foveal detachment before surgery. All patients underwent fovea-sparing internal limiting membrane peeling during vitrectomy and had improved vision at 3 months after surgery. Large intraretinal cavities were noted on optical coherence tomography at the first postoperative exam in three patients and 12 to 18 months postoperation in the other two. The median height of the postoperative intraretinal cavities was 704 μm (range, 445–1287 μm). Inner retinal breaks were identified in all eyes, of which four were located in the paravascular area. The intraretinal cavity and schisis remained stable during the initial follow-up for an average of 35 months; later on, at > 5 years after the initial presentation two patients developed retinal detachment and one patient underwent vitrectomy with the retina reattached postoperatively.

Conclusion

Large intraretinal cavities and schisis can be observed after MTM surgery, associated with paravascular inner breaks. The condition can progress after a long stable period; therefore, continuous follow-up is necessary.

高度近视术后大视网膜腔和劈裂伴血管旁内裂

目的

报告近视牵拉性黄斑病 (MTM) 手术后明显的结构变化。

学习规划

单中心回顾性病例系列。

方法

对接受玻璃体切除术并具有持续性大视网膜内腔和劈裂的 MTM 患者进行了审查。描述了术前和术后的临床表现和光学相干断层扫描的特征。

结果

该研究包括五名患者的五只眼睛。三名患者有明显的分裂，四名患者在手术前有视网膜/中央凹脱离。所有患者在玻璃体切除术期间均接受了保留中央凹的内界膜剥离术，并在术后 3 个月时视力得到改善。三名患者在术后第一次检查时光学相干断层扫描发现大的视网膜内空洞，另外两名患者在术后 12 至 18 个月发现大的视网膜内空洞。术后视网膜内腔的中位高度为 704 μm（范围，445-1287 μm）。所有眼睛均发现内部视网膜裂孔，其中四只位于血管旁区域。在平均 35 个月的初始随访期间，视网膜内腔和劈裂保持稳定；稍后，在 >

结论

MTM 手术后可以观察到大的视网膜内腔和劈裂，与血管旁内部破裂有关。经过长时间的稳定后，病情可能会进展；因此，需要持续跟进。
