Peripheral anterior synechiae（周边前房粘连，常缩写 PAS）指周边虹膜在前房角处与房角结构发生异常粘连，常见为虹膜与小梁网（trabecular meshwork）（有时可延伸至 Schwalbe 线等更前方结构）相互黏附。它可能阻碍房水外流、促发或加重闭角型青光眼/慢性房角关闭。 (vagelos.columbia.edu)

synechia / synechiae源自医学拉丁语，进一步来自古希腊语synekheia，本义与“连续、连在一起”相关，可拆解理解为 syn-（一起）+ ekhein（持有、握住），因此在医学上引申为“（组织）粘连”。 (etymonline.com)
