Methods Seven young Newzealand white rabbits were selected as experimental animals.At two-month-old ,all rabbits were killed and then zygomas were made into paraffin and electron microscope sections after they were decalcified. Apoptosis of osteocytes was observed by light microscope and transmission electron microscopes and detected by TUNEL staining. Results The classical apoptosis of osteocytes was found under light and transmission electron microscopes. Apoptosis of osteocytes was diffused irregularly in the zygomatic tissue. Conclusion Osteocyte can apoptosis and it may participate in the development of the bony orbit.展开更多

Tumor metastasis to the eye is a rare complication of lung cancer. Metastaticcancer to the ocular region most often involves the uveal tract, however, most uveal metastasesoccur in the posterior uvea, and iris metastases are relatively rare. We describe a patient withadenocarcinoma of the lung metastatic to the iris as the first clinical sign without symptoms oflung cancer.展开更多
