Abstract

An enucleated eye obtained post-mortem from a 95-year-old donor who had a 4-loop, iris-fixated (iris-clip) glass intraocular lens (IOL) that had been implanted 22 years earlier was analyzed. The patient had a history of mild corneal edema, glaucoma, and macular degeneration/macular pucker. High-frequency ultrasound showed a well-centered iris-fixated IOL. Gross and light microscopic analyses of the eye and the IOL showed fragments of iris tissue attached to the haptics, pigment dispersion within the eye, with pigmented epithelial cells attached to the lens haptics and interruptions of the iris pigmented epithelial layers, and signs of corneal decompensation.

摘要

对一只从一名95岁供体死后获取的眼球进行了分析，该供体22年前植入了一枚4袢、虹膜固定（虹膜夹）的玻璃人工晶状体（IOL）。患者有轻度角膜水肿、青光眼和黄斑变性/黄斑皱襞病史。高频超声显示虹膜固定型人工晶状体位置居中。对眼球和人工晶状体进行大体和光学显微镜分析，结果显示虹膜组织碎片附着于袢上，眼内有色素播散，色素上皮细胞附着于晶状体袢，虹膜色素上皮层中断，并有角膜失代偿迹象。
