摘要
目的 了解晶状体囊外摘出术后晶状体皮质的残留情况并探讨与后囊膜混浊的关系。方法 对 2 4只实验家兔行晶状体囊外摘出术。术前按瞳孔大小随机分为A、B两组 (A组瞳孔直径≥ 6 5mm ;B组瞳孔直径≤ 4 5mm)。术后 3个月对 2个组术眼进行裂隙灯、眼底、组织病理学及扫描和透射电镜检查。结果 术后 3个月B组术眼后囊膜混浊程度较A组明显 ,差异有显著性意义 (P <0 0 5)。A、B两组后囊膜均可见增生的晶状体上皮细胞和Elschnig小体。B组后囊膜皱缩较A组明显。B组晶状体赤道部残留有较多的皮质 ,形成典型的Soemmering环。结论 晶状体囊外摘出术后有不同程度的皮质残留。
OBJECTIVE To investigate condition of cortex remain and relationship with posterior capsular opacification(PCO) after extracapsular extraction of lens METHODS Extracapsular extraction of lens was performed in 24 rabbits They were randomly divided into 2 groups according to pupil diameter that was 6 5mm or more in the A group, and was 4 5mm or less in the B group At 3 months, the post-operative eyes were examined with slit lampmicroscope, ophthalmoscope, scanning and transmitting electron microscope for fundus and pathological changes RCSULTS The PCO were less in the A group than that group B ( P <0 05) There were lens epithelium and Elschnig′s pearls on the posterior capsule in the 2 groups The posterior capsule wrinkle was more obvious in the group B than in the group A There were many cortex remain and typical Soemmering′s ring in the group B CONCLUSIONS There are more or less cortex remain after extracapsular extraction of lens The amount of cortex remain relate to degree of the PCO
