SUMMARY Iris cyst occurs post intraocular -surgery or post penetrating trauma, when corneal epithelial cells or conjunctiva} epithcells gains access to the anterior chamber, with cells may continue to grow & covering all available surface and formed iris cyst. As the cyst grow may caused glaucoma or block pupil area & leads to vision treatment of all form of iris cyst and epithelial down growt...

purpose : to report two young patients with unilateral pseudoexfoliation (pex) syndrome case reports : two young patients with pex syndrome were examined. the first was a 30-year-old woman who had a history of penetrating ocular trauma with iris prolapse in the right eye that subsequently developed pex material deposition on pupillary border and anterior lens capsule. the second was a 13-year-o...

Many of the most interesting behaviors in the biological world have to do with interactions between species. The predator-prey interactions among aquatic organisms is an interesting part of the natural world which has not been seen much in computer animation. This paper explores the interaction between various sea anemones and the starfish Dermasterias imbricata. Although a simulation between a...

A rapid in vitro propagation system leading to the formation of shoots, calli, roots, cell suspensions and plantlets was developed for the Andean medicinal plant Fabiana imbricata (Solanaceae). Massive propagation of shoots and roots was achieved by the temporary immersion system (TIS), morphogenesis and maintenance of cell suspensions by standard in vitro culture techniques. Oleanolic acid (OA...

Iris recognition is one of the most reliable methods for identification. In general, itconsists of image acquisition, iris segmentation, feature extraction and matching. Among them, iris segmentation has an important role on the performance of any iris recognition system. Eyes nonlinear movement, occlusion, and specular reflection are main challenges for any iris segmentation method. In thi...
