ABSTRACT
Magnetic resonance imaging(MRI) is a non-invasive imaging technique of biological spin.MRI shows more advantages in imaging of orbital and ocular muscle than B-type sonography and X ray.MRI plays important roles in the study on anatomy of eye muscle,eye movements,survey of strabismus cause,also identification and diagnosis of strabismus.The imaging features,analysis of MRI,application of MRI in several special forms of strabismus were reviewed.
ABSTRACT
<p><b>OBJECTIVE</b>To detect the expression of basic fibroblast growth factor (bFGF) in human ocular tissues, and to assess the effect of bFGF on the proliferation of human cataract lens epithelial cells (LECs) and its correlation with age.</p><p><b>METHODS</b>Enucleated eyes were subjected to immunostaining for bFGF protein. Human cataract LECs were cultured in vitro, and treated with bFGF for 48 hr. Proliferation was estimated by the positive area ratio of proliferating cell nuclear antigen (PCNA) in immunohistochemistry.</p><p><b>RESULTS</b>bFGF protein was found in various human ocular tissues. bFGF stimulated human cataract LEC proliferation, and there was an age-related decrease in responsiveness of human cataract LECs to bFGF (P < 0.05).</p><p><b>CONCLUSION</b>bFGF might play an important role in the proliferation of residual human cataract LECs after cataract surgery.</p>
