Human vitreous transplantation.

This lecture presents the experience in 200 implantations of human eye-bank vitreous through the pars plana of eyes with complicated retinal detachments. Though the success rate was modest, it shows that a large-bore instrument can be passed into the vitreous cavity of the eye with relative impunity and sets the stage for the present popular machine vitrectomy. In addition, the paper presents the author's experience with human vitreous transplantation by the 'open sky' transcorneal technique for otherwise hopeless vitreous opacities.
