Vitrectomy in the treatment of ocular perforating injuries.

Using pars plana (closed) vitrectomy with related procedures we achieved improved vision in certain catagories of perforating ocular injuries. These procedures were particularly useful in removing retained nonmagnetic foreign bodies and correcting retinal detachments associated with traction bands and opaque vitreous. Limited success was obtained with longstanding injuries, double perforations from shotgun injuries, and large corneoscleral lacerations. Early vitreous surgery produced the best results.
