目的 观察晶状体前囊膜下上皮细胞增殖的组织病理学变化 ,并探讨其发生原因。方法 取不同病因致手术摘除的伴晶状体前囊膜下上皮细胞增殖的眼球标本 6 4例 ,其中眼外伤 36例 ,绝对期青光眼 10例 ,角巩膜葡萄肿 6例 ,视网膜母细胞瘤 5例 ,眼内炎 4例 ,白内障手术后 2例 ,糖尿病性白内障 1例 ,在光镜下进行组织病理学观察研究。结果 增殖的晶状体前囊膜下上皮细胞形态不规则、排列不整齐 ,向后囊膜下延伸 ;囊膜破裂或部分缺如者前囊膜下纤维结缔组织化生 ,纤维组织形成 ;晶状体纤维崩解、液化和钙化。结论 眼内多种病理状态 ,如眼外伤、眼内炎、青光眼 ,以及糖尿病等全身疾患均可使晶状体前囊膜下上皮细胞增殖 ,导致晶状体发生病变。眼内炎和眼外伤后晶状体发生增殖的程度最重。
Objective To observe the histopathological changes of the anterior lens epithelial cell proliferation and to explore its cause. Methods Sixty-four eyes of proliferative eyeball specimens with different etiology were enucleated, including 36 cases of ocular trauma, 10 cases of absolute glaucoma, 6 cases of corneal and staphyloma, 5 cases of retinoblastoma, 4 cases of endophthalmitis, 2 cases of cataract surgery, 1 case of diabetic cataract, histopathological observation under light microscope. Results Proliferation of the anterior lens epithelial cells in the shape of irregular, irregular arrangement, backward subcaptimal extension; rupture of the capsule or part of the anterior subcapillary fibrous connective tissue formation, fibrous tissue formation; lens fiber collapse Solution, liquefaction and calcification. Conclusion Various intraocular pathological conditions, such as ocular trauma, endophthalmitis, glaucoma, and other systemic diseases such as diabetes, can proliferate the anterior lens epithelial cells and lead to lens lesion. Endophthalmitis and ocular trauma after the proliferation of the most serious lens.
