Histopathological findings in 33 intracapsularly removed lenses and 35 enucleated eye-balls are presented. Anterior and posterior subcapsular cataracts were mostly seen in traumatic and advanced senile cataracts. Characteristic features of the latter were cortical degeneration and liquefaction with formation of Morgagnian globules and nuclear sclerosis. Anterior lens epithelium had more tendency to undergo fibrous pseudometaplasia, while equatorial epithelium migrated posteriorly with "bladder cell" formation. In complicated and traumatic cataracts, apart from abnormal proliferation of lens epithelium, frequent synechiae with iris and/or cyclitic membranes were seen. Phacoanaphylactic uveitis was observed in 6 eyes with capsular defects. Pseudoexfoliative material was found in 5 cases. It is suggested, that domination of proliferative changes in traumatic and complicated cataracts, in contrast to senile cataracts, results from the availability of different mitogenic factors in injured and inflammed eyes and may be due to the younger age of patients in this group.
本文呈现了33个囊内摘除晶状体及35个眼球摘除标本的组织病理学发现。前囊下和后囊下白内障多见于外伤性和晚期老年性白内障。后者的特征性表现为皮质变性、液化，形成莫尔加尼小球及核硬化。晶状体前上皮更易发生纤维性假化生，而赤道部上皮向后迁移形成“膀胱细胞”。在复杂性和外伤性白内障中，除晶状体上皮异常增殖外，还常见与虹膜和/或睫状体膜的频繁粘连。6例有囊膜缺损的眼中观察到了晶状体过敏性葡萄膜炎。5例发现有假性剥脱物质。提示外伤性和复杂性白内障中增殖性改变占主导，与老年性白内障不同，这是由于受伤和炎症眼中存在不同的促有丝分裂因子，也可能与该组患者年龄较轻有关。
