　　患者11岁，由于右眼发红、视力模糊3天就诊。右眼最佳矫正视力20/60，左眼20/20;右眼眼压29mmHg ，左眼13mm Hg。裂隙灯检查显示前房块状物，占据整个瞳孔区。没有葡萄膜炎或其它炎症表现。眼前节OCT确诊右眼巨大虹膜囊肿，未涉及睫状体。手术切除囊肿。在2点位置行1mm角膜切口，使用胰岛素针抽吸囊肿内容物。1月后随访，双眼视力20/20，眼压14mmHg。

　　An 11-year-old child was admitted to the hospital because of blurred vision and redness for 3 days in his right eye. Best corrected visual acuity was 20/60 right eye (OD) and 20/20 left eye (OS), intraocular pressure was 19 mm Hg OD and 13 mm Hg OS. Slit lamp examination revealed a mass occupying almost half of the anterior chamber and entire pupillary area (figure 1). No uveitis or any other sign of inflammation was present. Anterior segment optical coherence tomography confirmed the diagnosis of a giant iris cyst OD without any involvement of the ciliary body (figure 2). The patient underwent surgical evacuation of the cyst. The procedure was the following: corneal incision of 1 mm was made in the 2 o'clock position (OD) and aspiration of cyst's content with insulin needle was performed. At 1 month postoperatively the visual acuity was 20/20 in both the eyes (OU) and intraocular pressure was 14 mm Hg OU. No uveitis or any inflammation was present.
