dc.description.abstract | The ultrastructure of the proliferative vitreoretinal membranes in various eye
conditions such as peripheral uveitis, penetrating eye injury, aphakic retinal detachment, and traction retinal detachment were studied in human, and experimental study was performed in 27 pigmented rabbits to investigate the origin of cells participating in healing process of retinal injuries. The experimental rabbits were divided into two groups according to the degree of retinal injury; mild injury and severe injury groups. The retinal injury was made on avascular retina two disc diameters below the optic disc by gentle touch with a 21 gauge needle tip inserted through pars plana of rabbit eyes. The mild injury revealed a faint scratch line on the retinal surface. The severe injury was made in the same way but retinal scratch was so deep that choroidal damage and visible retinal hemorrhage were complicated. The following conclusions were obtained. 1. The proliferative vitreoretinal membranes of various eye conditions were composed mainly of fibrocyte-like cells and glial cells, and the retinal pigment epithelial cells were not found in the membranes formed without retinal break. 2. In the mild injury group of experimental animal, only the glial proliferation was noted in the case of the mechanical injury confined to the inner layer of the retina, and the retinal pigment epithelial cells were found to proliferate and migrate into the inner layer when the retinal damage extended to the outer retinal layer. 3. In the severe injury group, the proliferation of the choroidal fibroblast was noted. On the basis of the above findings, it is suggested that the fibrocyte-like cells found at the vitreoretinal membranes in eyes with nonrhegmatogenous retinal detachment or without retinal detachment, are not derived from the retinal pigment epithelial cells. | - |
