To search for a pathogenic mechanism for the formation of the precapsular layer on the anterior lens surface in pre-exfoliative eyes.
We examined anterior lens capsules obtained during surgery from 38 patients (control, 16; exfoliation suspect, 10; exfoliation, 12) by transmission electron microscopy.
A precapsular layer was found in 5 of 16 controls and 7 of 10 exfoliation suspects. It was composed mainly of microfibrils 5-8 nm in diameter. Degenerated zonular fragments were occasionally found interspersed in, and sometimes merged with microfibrils of the precapsular layer.
Zonular fibers might contribute to the formation of the precapsular layer in pre-exfoliation stages.
探寻剥脱前期眼晶状体前表面前囊膜层形成的致病机制。
我们通过透射电子显微镜检查了38例患者手术中获取的晶状体前囊膜（对照组16例；疑似剥脱组10例；剥脱组12例）。
在16例对照组中有5例发现前囊膜层，10例疑似剥脱组中有7例发现。其主要由直径5 - 8纳米的微原纤维组成。偶尔发现退化的悬韧带碎片散布其中，有时与前囊膜层的微原纤维融合。
悬韧带纤维可能在剥脱前期阶段促成前囊膜层的形成。
