Cell density dependency of vitreous fibrosis induced by monocytes and lymphocytes.

The possible roles of monocytes and lymphocytes in vitreous fibrosis were examined by injecting various numbers of the peripheral cell types into the rabbit vitreous. Our results indicated that the degree of vitreous fibrosis and the presence of traction retinal detachment corresponded to the number of cells injected. It was suggested that these findings are probably similar to vitreous membrane formation and retinal detachment in various clinical ocular diseases or inflammations in humans.
