The authors performed experimental study to produce proliferative vitreoretinopathy by intravitreal injection of homologous fibroblasts in pigmented rabbits. Twenty four eyes of 12 rabbits were divided into control and experimental groups. In experimental group, the eyes were pretreated with expanding gas, perfluoropropane for the vitrectomy. In control group, no such procedure was preceded. In both groups, 5.0×10⁴, 1.0×10⁵ and 1.5×10⁵ cells of homologous fibroblasts were injected into the vitreous cavity. All the eyes were observed regularly with indirect ophthalmoscope followed by fundus photography. Those eyes were enucleated in 1, 2, 4 weeks for the light and electron microscopic studies. The development and severity of the proliferative vitreoretinopathy were correlated with the numbers of the injected fibroblast. This was more pronounced in the experimental group.

Extraskeletal Neoplasm Resembling Ewings Sarcoma was firstly reported with comprehensive review of 39 cases by L. Angervall and F.M. Enzinger in 1975. The tumors chiefly affected young adults and most commonly involved the soft tissue of lower extremity. Microscopically, they were consisted of solidly packed small, round or ovoid cells arranged in sheets or lobules, which were indistinguishable from those of the Ewings sarcoma of bone. The authors recently experienced a soft tissue sarcoma occurring in deltoid area of young male patient, which was diagnosed extraskeletal neoplasm resembling Ewings sarcoma. The case review is presented.

We performed 16 dacryocystorhinostomies with silicone tube for the chronic dacryocystitis with partial obstruction of the canaliculus. About 10 weeks postoperatively, the silicone tube was removed in 6 cases which had some epiphora, and the tube was retained in the canlaiculus in asymtomatic 10 cases. After 6 months follow up period, one case revealed a reobstruction of the common canaliculus but the other fifteen cases showed satisfactory results.
