An unusual case of a free-floating peripheral pigmented cyst in the anterior chamber is presented. A 30-year-old Caucasian male presented reporting a visual defect on his right eye in prone position over the past year. Slit-lamp examination revealed a small pigmented free-floating peripheral iris cyst at the 6 o'clock position in the anterior chamber. Ultrasound biomicroscopy revealed an unfixed epithelial pigmented cyst with an extremely thin wall and no internal reflectivity. Due to the lack of severity of visual disturbance of the patient, no surgical treatment was indicated. The patient is to be followed up annually and advised to return immediately in case of pain or any visual symptoms. Free-floating iris cysts in the anterior chamber are uncommon and remain stable in the majority of cases. Management includes only regular observation until any complications arise.
本文报告了一例前房内游离漂浮的周边色素性囊肿的罕见病例。一名30岁的白种男性报告称，在过去一年中，他俯卧位时右眼出现视力缺陷。裂隙灯检查发现前房6点钟位置有一个小的色素性游离漂浮周边虹膜囊肿。超声生物显微镜检查显示一个未固定的上皮色素性囊肿，壁极薄且无内部反射。由于患者视力障碍不严重，未采取手术治疗。建议患者每年随访，如有疼痛或任何视觉症状应立即复诊。前房内游离漂浮的虹膜囊肿并不常见，大多数情况下保持稳定。处理方法仅包括定期观察，直至出现任何并发症。
