Two unusual events concerning intraocular foreign bodies are presented. The first patient had an occult or unsuspected intraocular foreign body. He showed iridoplegia with mydriasis, siderosis iridis, and an intraocular piece of iron lying posteriorly near the retina. The foreign body was removed and the patient regained normal iris color and pupillary activity. His vision remains 20/15 six years postoperatively dispite ensuing retinal detachment one year after removal of the foreign body. The second patient was a young boy injured by a blasting cap explosion. He lost one eye from the injury and had a piece of intraocular brass in his left eye. In spite of the development of chalcosis and a mature cataract the lens gradually shrank in the pupillary space permitting a clear aphakic area and 20/25 vision. The brass fragment migrated forward and inferiorly and was finally extruded under the conjunctiva five years later, where it was removed and chemically analyzed by x-ray diffraction.
本文介绍了两例关于眼内异物的特殊病例。第一例患者有一个隐匿性或未被怀疑的眼内异物。他表现为虹膜麻痹伴瞳孔散大、虹膜铁质沉着症，以及一枚位于视网膜后方的眼内铁片。异物被取出后，患者的虹膜颜色和瞳孔活动恢复正常。尽管在异物取出一年后发生了视网膜脱离，但术后六年他的视力仍保持在20/15。第二例患者是一名因雷管爆炸受伤的小男孩。他因伤失去了一只眼睛，左眼有一块眼内黄铜碎片。尽管发生了铜质沉着症和成熟白内障，但晶状体在瞳孔空间逐渐缩小，形成了一个清晰的无晶状体区，视力为20/25。五年后，黄铜碎片向前下方移动，最终在结膜下挤出，在那里被取出并通过X射线衍射进行化学分析。
