A rare case of binocular polycoria due to extensive persistence of the pupillary. membrane was reported. Central visions of both eyes in this case were not disturbed because of the presentation of few holes in the thick pupillary membranes.

The extracellular proteins bound with the membrane through the sites of glucosyl-phosphat idylinositol (GPI) to generate the complexes of protein with GPI. The GPIs have concentrated structure to generate glycolipid rich sites in the membrane. These sites have inert property with detergent. The GPI bound extracellular proteins can transmit the sign to cells. This sign is the same as this transmitted from receptor MD. The exist of structure GPI may be an example of the concentration of many suitable molecules which intact mutually to implement optimal a function. These GPI related with the costimulation phenomena and their play likes as a synapse MD

Membrane creates the functions of protection, supporting, dispersion and separation. More functions can be designed by modifying membrane surface and grafting/loading selective ligands or catalysts on the membrane, thus membrane technology has been widely applied in biological detection, and its application approaches becomes diverse. Rational design of functional membranes can meet the demands in different steps of biological detection process, including sample pretreatment, preparation, response and sensing. This review summarized the functionalization methods of filtration membranes, applications of membrane technology in sample preparation and detection process, as well as the research on the integration of functional membranes. By revisiting the research progress on functional membrane design, preparation and applications for biological detection, it is expected to take better advantage of membrane materials structure and performance for constructing efficient and stable detection platform, which is more "adapted" to the detection environment.

The results of diabetic vitrectomy on eyes with severe proliferative fibrovascular membranes are often disappointing, because of difficulties in removing the membranes. But we sometimes observe the regression of the proliferative fibrovascular membranes when the antero-posterior tractional force become released. Hence we compared the surgical prognosis of proliferative diabetic retmopathy according to the severity of proliferation and whether removal of antero-posterior vitreoretinal traction was complete or not. The results showed that the anatomic success rate and final visual acuities(VA) were significantly better in less-severe proliferation group(LSPG) than in severe prolif era tion group(SPG). In SPG, the anatomic success rate and VA tended to be better when we were able to remove the antero-posterior vitreoretinal adhesion completely whether the removal of preretinal membranes was complete or not. When complete removal of the diabetic fibrovascular membrane is difficult due to severe proliferation and broad adhesion, complete removal of anter-posterior traction only could be an alternative in diabetic vitrectomy.
