title: [Vitrectomy: measures for the prevention of intraoperative complications].
abstract: Problems during a pars plana vitrectomy, such as infusion terminal within a detached choroid or behind the retina, and opacities of the cornea and lens may be prevented by simple means. These include introduction of the infusion terminal using a trocar; using a scleral ring for miniature contact lenses, which is fixed by sutures to the four rectus muscles; and in incipient opacification of the corneal epithelium, irrigation of the cornea with a solution of 50% glucose may render removal of the corneal epithelium unnecessary. Opacification of the cornea and lens can also be prevented by using glucose (500 mg/100 ml) in the intraocular irrigation solution.
