Small traumatic iridodialysis (ID) may be asymptomatic, but large ones usually cause polycoria and corectopia, leading to symptoms like diplopia, glare, and photophobia. The management of ID, including medical and surgical methods, depends upon the patient's symptoms. Mild glare and diplopia can be treated either with atropine, antiglaucoma medications, tinted spectacles, colored contact lens, or corneal tattooing, but extensive IDs require surgical options. The surgical techniques are challenging due to the iris texture and the damage encountered during the primary surgery, the narrow anatomical workspace for repair, and the associated surgical complications. Numerous techniques have been described by several authors in the literature; each has its advantages and disadvantages. All the procedures described previously involve conjunctival peritomy, scleral incisions, and suture knots and are time consuming. Here, we report a novel transconjunctival, intrascleral, knotless, and ab-externo, double-flanged technique for repair of large ID with a 1-year follow-up.
小的外伤性虹膜根部断离（ID）可能无症状，但大的 ID 通常会导致瞳孔多、虹膜偏位，导致复视、畏光等症状。ID 的处理，包括药物和手术方法，取决于患者的症状。轻度的畏光和复视可以通过阿托品、抗青光眼药物、有色眼镜、彩色隐形眼镜或角膜纹身来治疗，但广泛的 ID 需要手术选择。由于虹膜质地和初次手术中遇到的损伤、修复的狭窄解剖工作空间以及相关的手术并发症，手术技术具有挑战性。许多作者在文献中描述了多种技术；每种技术都有其优缺点。之前描述的所有程序都涉及结膜周切除术、巩膜切口和缝线结，并且耗时较长。在这里，我们报告了一种新颖的经结膜、巩膜内、无结、外切的双翼瓣技术，用于修复大的 ID，随访 1 年。
