To present a relatively uncommon case with a secondary iris cyst in the anterior chamber and its successful management with an anterior chamber mass excision surgery.
A 46-year-old Chinese woman presented with a dark shadow in her left eye for 6 months without any other discomfort. She had a history of blunt ocular trauma by a badminton strike 3 years ago. Slit-lamp examination showed a small, nearly circular, sharply demarcated, and movable mass in the anterior chamber OS, which could change its position with head tilt. The anterior segment optical coherence tomography revealed a well-circumscribed cystic lesion in the anterior chamber with higher reflective outer layer and lower internal reflectivity. An anterior chamber mass removal surgery was performed without recurrence up to 1 year.
Secondary free-floating iris cyst following a blunt trauma is rarely reported. It is relatively stable and nonprogressive so it may remain asymptomatic for a long time. Appropriate imaging techniques are necessary for facilitating diagnosis and therapy. Therapeutic management should be considered if visual symptoms arise, especially when complications occur.
介绍一例前房继发性虹膜囊肿，该病例较为罕见，通过前房肿块切除术获得成功治疗。
一名 46 岁的中国女性因左眼出现黑影 6 个月就诊，无其他不适。患者 3 年前曾被羽毛球击中眼部，有钝挫伤史。裂隙灯检查显示左眼眼前段有一个小的、近圆形、边界清晰、可移动的肿块，可随头位改变位置。眼前段光学相干断层扫描显示前房有一个边界清晰的囊性病变，外层高反射，内层低反射。行前房肿块切除术，1 年随访无复发。
钝挫伤后继发性游离虹膜囊肿较为罕见。它相对稳定且无进展性，因此可能长时间无症状。适当的影像学技术有助于诊断和治疗。如果出现视力症状，特别是出现并发症时，应考虑治疗。
