The interaction between the peripheral vitreous and retina is closely associated with the pathogenesis of rhegmatogenous retinal detachment (RRD). This study was conducted to examine the peripheral vitreous and retina in patients with RRD using intraoperative optical coherence tomography (iOCT).
This retrospective study included 50 eyes of 50 patients (mean age 59.42 ± 10.80 years) that underwent vitrectomy using iOCT for treating RRD at the Yamagata University Hospital between September 2015 and September 2016. Each patient underwent 25-gauge pars plana vitrectomy that was performed by a single surgeon. During vitreous shaving with ocular indentation, the iOCT findings of the peripheral vitreous and retina were recorded and analyzed postoperatively.
In all patients, iOCT was able to detect the peripheral retina and vitreous around the vitreous base. Peripheral cystoid degeneration was detected on the peripheral retina of 27 eyes (54%). Furthermore, cystoid degeneration was detected around the retinal tear (5 patients), at the detached retinal area (8 patients), and at the attached retinal area (14 patients).
iOCT enabled the evaluation of peripheral cystoid degeneration in patients with RRD. Cystoid degeneration might be associated with the pathogenesis of RRD.
周边玻璃体与视网膜之间的相互作用与孔源性视网膜脱离（RRD）的发病机制密切相关。本研究旨在使用术中光学相干断层扫描（iOCT）检查RRD患者的周边玻璃体和视网膜。
这项回顾性研究纳入了2015年9月至2016年9月期间在山形大学医院接受iOCT玻璃体切除术治疗RRD的50例患者的50只眼（平均年龄59.42±10.80岁）。每位患者均接受由单一外科医生进行的25G标准三通道玻璃体切除术。在眼球压迫下行玻璃体切除时，记录周边玻璃体和视网膜的iOCT检查结果，并在术后进行分析。
在所有患者中，iOCT均能够检测到玻璃体基底部周围的周边视网膜和玻璃体。在27只眼（54%）的周边视网膜上检测到周边囊样变性。此外，在视网膜裂孔周围（5例患者）、视网膜脱离区域（8例患者）和视网膜附着区域（14例患者）检测到囊样变性。
iOCT能够评估RRD患者的周边囊样变性。囊样变性可能与RRD的发病机制有关。
