Free-floating iris pigment epithelial cysts in the vitreous are very rare. We report the case of a partially pigmented cyst found on routine examination in the vitreous of a 51-year-old asymptomatic patient. Usually, non-pigmented cysts are derived from the hyaloid system. Pigmented cysts, however, are derived from the iris pigment epithelium. When they are not dislodged, these cysts can be confused with iris melanoma or primary stromal cysts. Treatment is usually unnecessary, unless they become symptomatic.
玻璃体中游离的虹膜色素上皮囊肿非常罕见。我们报告了一例在一名51岁无症状患者的玻璃体常规检查中发现的部分色素沉着囊肿。通常，无色素囊肿来源于玻璃体系统。然而，色素囊肿来源于虹膜色素上皮。当这些囊肿未移位时，可能会与虹膜黑色素瘤或原发性基质囊肿混淆。通常无需治疗，除非它们出现症状。
