Abstract：
BACKGROUND: Equine primary iris cysts are usually incidental findings but, if associated with clinical signs, may require intervention. The use of laser (Nd:Yag or diode) has been reported but requires specialised equipment. Transcorneal aspiration has not been previously evaluated in the standing horse.
OBJECTIVE: To review outcomes of standing transcorneal aspiration of primary iris cysts (STAPIC) in horses.
METHODS: Horses were identified from electronic patient records from 2018 to 2024 across four collaborating centres. Clinical presentation and outcomes were identified and reported using descriptive statistics.
RESULTS: Eighteen horses were identified. Behavioural signs reported included \'spooking\' and changes in rideability often associated with jumping. Single large unilateral cysts were present in 11 horses, bilateral cysts in three horses and multiple unilateral cysts in four horses. Following treatment, one horse developed uveitis and fibrin in the anterior chamber associated with needle contact with the iris stroma due to movement, and a second horse developed fibrin within the anterior chamber. Both conditions resolved with anti-inflammatory medication and administration of tissue plasminogen activator. No other adverse effects were reported. Follow-up was available from all horses (median: 6 months, interquartile range [IQR]: 4-11 months) with no recurrence, although one horse developed an iris cyst in the contralateral eye after 3 years. All owners reported improvement in clinical signs, with 61% reporting no further signs.
CONCLUSIONS: STAPIC is an effective and easily accessible alternative for treating iris cysts in horses rarely associated with complications.

摘要：
背景：马原发性虹膜囊肿通常是偶然发现，但是，如果与临床症状有关，可能需要干预。已经报道了激光(Nd:Yag或二极管)的使用,但是需要专门的设备。先前尚未在站立的马中评估过经角膜抽吸。
目的：回顾马原发性虹膜囊肿（STAPIC）的站立性经角膜抽吸术的结果。
方法：从2018年至2024年在四个合作中心的电子病历中确定了马。使用描述性统计识别和报告临床表现和结果。
结果：鉴定出18匹马。报告的行为体征包括“惊吓”和通常与跳跃相关的可乘坐性变化。11匹马存在单个大的单侧囊肿，三匹马的双侧囊肿和四匹马的多个单侧囊肿。治疗后,一匹马由于运动而在与虹膜基质接触的针头相关的前房中出现葡萄膜炎和纤维蛋白，第二匹马在前房内出现纤维蛋白。两种情况都通过抗炎药和组织纤溶酶原激活剂的给药解决。未报告其他不良反应。所有马匹均可进行随访（中位数：6个月，四分位间距[IQR]：4-11个月）无复发，虽然一匹马3年后在对侧眼出现虹膜囊肿。所有业主报告临床症状有所改善，61%的人报告没有进一步的迹象。
结论：STAPIC是治疗很少与并发症相关的马虹膜囊肿的一种有效且容易获得的替代方法。
