Abstract:
Objective There are a few reports on rats with spontaneous congenital cataract in China .The purpose of this study was to investigate the morphological changes of lens in rats with spontaneous congenital cataract . Methods 24 d, 1-year rats with cataract and microphthalmos cataract and normal rats (n=5) were selected as research objects .Their lens were observed by a slit lamp microscope and taken photos in front of them , followed by examination through light micrograph and transmission electron micros-copy. Results Rats with microphthalmos cataract showed narrowed palpebral fissure and broaden nucleus while rats with cataract showed normal palpebral fissure and narrowed nucleus .As for 24 d,1-year rats with microphthalmos cataract , the fibers of their lens showed derangement and vacuole-like degeneration by light microscope , in addition, the abnormal connection between fiber cells were observed by electron microscopy .As for 1-year normal rats , the fibers were in consistent structure and regular arrangement without cell ingredient . Conclusion The appearance and morphological changes of the lens in rats with spontaneous congenital cataracts are in consistence with the pathological changes of cataracts , which is appli-cable in further research on the pathogenesis of cataract .
