One hundred and ninety flat preparations of human lens epithelium attached to the anterior capsule, obtained during surgical extracapsular cataract extraction (ECCE), were studied. The median cell density of all preparations was 4,701 cells/sqmm. The lens epithelium of the patients exceeding 50 years of age showed lower density than that of younger patients (p less than 0.05). The epithelium of females showed a higher density than that of male patients. With increasing maturity of cataracts, the cell density decreased (p less than 0.05). Moreover the cell density of DM patients was significantly lower than that of non-DM patients (p less than 0.05). This result may be explained by the sorbitol pathway theory. There were no significant differences among any cases in term of hexagonality.
对在白内障囊外摘除术(ECCE)过程中获取的190份附着于前囊的人晶状体上皮平铺标本进行了研究。所有标本的细胞密度中位数为4701个细胞/平方毫米。50岁以上患者的晶状体上皮密度低于年轻患者(p<0.05)。女性患者的上皮细胞密度高于男性患者。随着白内障成熟度增加,细胞密度降低(p<0.05)。此外,糖尿病患者的细胞密度显著低于非糖尿病患者(p<0.05)。这一结果可用山梨醇途径理论来解释。在六边形方面,各病例之间无显著差异。
