To report the long-term follow-up and visual outcome after excision of a traumatic iris cyst. A 4-year-old female presented with an iris cyst in her left eye 2 years after corneal laceration repair. An 8 × 7 mm cyst was located between 1 and 6 O'clock on the iris, extending into the anterior chamber. The cyst was surgically removed by dissection from the endothelium and angle by viscoelastic and was submitted for histopathological examination. Postoperative outcomes including visual acuity (VA) and complications over 8 years are reported. Histopathological examination demonstrated fragments of iris tissue extensively covered by a layer of epithelial cells which were present on both the anterior and posterior surfaces of portions of the iris stroma. 8 years post-excision, the patient's VA improved from 20/80 to 20/30 with no evidence of recurrence and no adverse sequelae. Traumatic iris cyst is a diagnostic and therapeutic challenge for ophthalmic surgeons with an overall poor visual prognosis if it is not excised properly. Improved wound management techniques during the repair of a traumatic wound are highly recommended. Careful viscoelastic dissection of the iris cyst from the endothelium and angle provided acceptable long-term outcome and prevented recurrence.
报告外伤性虹膜囊肿切除术后的长期随访及视力结果。一名4岁女性在角膜裂伤修复2年后左眼出现虹膜囊肿。一个8×7毫米的囊肿位于虹膜的1点至6点之间，延伸至前房。通过粘弹剂从内皮和房角进行分离手术切除囊肿，并进行组织病理学检查。报告了术后8年的视力（VA）等结果及并发症。组织病理学检查显示虹膜组织碎片被一层上皮细胞广泛覆盖，这些上皮细胞存在于虹膜基质部分的前表面和后表面。切除术后8年，患者视力从20/80提高到20/30，无复发迹象及不良后遗症。外伤性虹膜囊肿对眼科医生来说是诊断和治疗上的挑战，如果切除不当，总体视力预后较差。强烈建议在创伤性伤口修复过程中改进伤口处理技术。从内皮和房角仔细地用粘弹剂分离虹膜囊肿可提供可接受的长期结果并防止复发。
