It was reported by Brindley (1, 3, 5) that there is a layer of high electrical resistance and capacitance termed the R membrane in the retina and that the E R G develops across this membrane. He considers that the R membrane is the external limiting membrane. O n the other hand, Brown and Wiesel (6) who worked more recently on the unopened cat's eye with microelectrodes concluded that the P, me...

Retinal anatomy [1] The retina is a many layered structure. From the inner (vitreous) surface to the choroid these are the internal limiting membrane, nerve fibre layer, ganglion cell layer, inner plexiform layer, inner nuclear layer, outer plexiform layer, outer nuclear layer, external limiting membrane, rod and cone inner and outer segments and a single layer of cells called the retinal pigme...

The retina is a many layered structure and retinal dystrophies may affect any of the layers. From the vitreous to the choroid these are the internal limiting membrane, nerve fibre layer, ganglion cell layer, inner plexiform layer, inner nuclear layer, outer plexiform layer, outer nuclear layer, external limiting membrane, rod and cone inner and outer segments and the retinal pigment epithelium ...

The external limiting membrane of the avian embryonic optic tectum is isolated by mechanically separating the neuronal mesencephalon from the overlying mesenchymal tissue. The preparation consists of a basal lamina which is covered on its neural side by endfeet of neuroepithelial cells and has attached to it on its meningeal side a collageneous stroma, containing blood vessels. The external lim...

in this research, modeling of limiting flux in membrane filtration of skimmed milk as well as the results of simulation by matlab is presented. the presented model is actually a force balance approach and consists of drag, gravitational and lift forces, and forces between colloidal particles (electrostatic repulsive and van der waals attractive forces). to consider the back diffusion phenomenon...

PURPOSE To investigate the change in integrity and thickness of the foveal outer retina in eyes with chronic cystoid macula edema associated with retinal vein occlusion. METHODS We reviewed retrospectively the medical records of 30 eyes of 30 patients who had chronic cystoid macula edema associated with retinal vein occlusion and who had a follow-up of more than 12 months without any treatmen...
