我们研究了一位82岁的白色供体的眼球摘除术，该供体在大约20年前在前房植入了Pannu“通用”人工透镜（IOL）。该IOL具有单件式C形环后房型IOL的设计特征。磁共振成像显示前房内IOL相对居中，支撑襻撞击虹膜。眼睛和IOL的大体和光学显微镜分析显示，周边前粘连包围一个支撑襻、角增宽区域、角膜内皮显著衰减、继发于光学部和支撑襻虹膜磨损的多个虹膜创伤区域、角内大面积色素分散、前房内弥漫性色素积聚和神经节细胞层衰减。组织病理学结果与青光眼和慢性炎症一致。财务披露：没有作者在提到的任何材料或方法中拥有经济或所有权利益。
We studied an enucleated postmortem eye from an 82-year-old white donor who had been implanted with a Pannu “universal” intraocular lens (IOL) in the anterior chamber approximately 20 years earlier. This IOL has design features characteristic of a 1-piece, C-loop posterior chamber IOL. Magnetic resonance imaging showed a relatively well-centered IOL in the anterior chamber with haptics impinging on the iris. Gross and light microscopic analyses of the eye and the IOL showed peripheral anterior synechiae enclaving one haptic, areas of angle widening, significant attenuation of the corneal endothelium, multiple areas of iris trauma secondary to optic and haptic iris abrasion, large areas of pigment dispersion in the angle, diffuse pigment accumulation within the anterior chamber, and attenuation of the ganglion cell layer. The histopathological findings were consistent with glaucoma and chronic inflammation. FINANCIAL DISCLOSURE: No author has a financial or proprietary interest in any material or method mentioned.
