To describe the removal of an adherent, presumed plant-based, anterior chamber foreign body (ACFB) from the inferior iridocorneal angle in a dog using hydropulsion and ophthalmic viscoelastic device (OVD) capture.
A 6-year-old female spayed pit bull terrier who was referred for further evaluation of a corneal opacity after being observed running into a thorned succulent plant 1 month earlier. On ophthalmic examination, no corneal foreign body was noted, though mild uveitis was present. Gonioscopy revealed a suspected plant foreign body (thorn tip) in the inferior iridocorneal angle.
Under general anesthesia, the ACFB was dislodged from the inferior iridocorneal angle using hydropulsion with balanced salt solution. The superior half of the anterior chamber had been filled with 2% hydroxypropyl methylcellulose OVD to trap the foreign object. One month later, the uveitis had resolved and repeat gonioscopy confirmed the absence of any ACFB in the iridocorneal angle.
In the absence of an intraoperative goniolens or endoscopy, hydropulsion and OVD capture of adherent ACFBs may be a feasible option for removal.
描述使用水动力冲洗和眼科粘弹剂（OVD）捕获技术，从一只犬的虹膜角膜下角取出一个粘连的、推测为植物性的前房异物（ACFB）的过程。
一只6岁已绝育的雌性比特斗牛梗犬，1个月前被观察到撞到一株带刺多肉植物后，因角膜混浊前来进一步评估。眼科检查未发现角膜异物，但存在轻度葡萄膜炎。前房角镜检查发现虹膜角膜下角疑似有植物性异物（刺尖）。
在全身麻醉下，使用平衡盐溶液进行水动力冲洗，将ACFB从虹膜角膜下角冲出。前房上半部分已注入2%羟丙基甲基纤维素OVD以捕获异物。1个月后，葡萄膜炎已消退，再次进行前房角镜检查确认虹膜角膜角没有任何ACFB。
在没有术中前房角镜或内镜的情况下，水动力冲洗和OVD捕获粘连的ACFB可能是一种可行的取出方法。
