To report the characteristics of retinal detachment demarcation lines on infrared imaging together with retinal detachment progression analysis.
We performed a retrospective case series of 25 eyes of 24 patients who underwent macula off rhegmatogenous retinal detachment (RRD) repair and demonstrated a postoperative demarcation line on in infrared imaging. All patients had an optical coherence tomography imaging at baseline capturing the extent of the RRD. Criteria for demarcation lines diagnosis on infrared imaging included a line parallel and with the same contour of the RRD edge. These lines were not observed on infrared imaging before RRD repair surgery.
Demarcation lines' hyperreflectivity was situated in the interdigitation-ellipsoid zone complex. These lines were more obvious on the early postoperative week but faded over time (average disappearance time 2.6 ± 2.9 months). The analysis of retinal detachment progression showed that superior RRDs progressed more than inferior RRDs (611 vs. 122 μ , P = 0.02). Among 13 cases with a superior RRD, the temporal border progressed more than the nasal side (697 vs. 426 μ , P = 0.01, Figure 1). The use of intraoperative perfluorocarbon was associated with less RRD progression ( P = 0.01).
The study concludes that demarcation lines are distinct findings on infrared imaging, appearing early but diminishing relatively quickly after RRD repair. It also revealed the characteristics of RRDs progression specifically that inferior RRDs and perfluorocarbon use were associated with less retinal progression.
报告视网膜脱离分界线在红外成像上的特征，并进行视网膜脱离进展分析。
我们对24例患者的25只眼进行了回顾性病例系列研究，这些患者均接受了黄斑脱离性孔源性视网膜脱离（RRD）修复术，且术后红外成像显示有分界线。所有患者在基线时均进行了光学相干断层扫描成像，以捕捉RRD的范围。红外成像上分界线诊断标准包括与RRD边缘平行且轮廓相同的线。在RRD修复手术前的红外成像上未观察到这些线。
分界线的高反射性位于指状交叉-椭球体区复合体。这些线在术后早期更明显，但随时间逐渐消退（平均消失时间2.6±2.9个月）。视网膜脱离进展分析表明，上方RRD的进展比下方RRD更多（611 vs. 122μm，P = 0.02）。在13例上方RRD患者中，颞侧边界的进展比鼻侧更多（697 vs. 426μm，P = 0.01，图1）。术中使用全氟碳化合物与RRD进展较少相关（P = 0.01）。
该研究得出结论，分界线是红外成像上的独特表现，在RRD修复后出现早但消退相对较快。它还揭示了RRD进展的特征，特别是下方RRD和使用全氟碳化合物与视网膜进展较少相关。
