Continuous vitreous insufflation of air into the vitreous cavity can reattach rhegmatogenous retinal detachments in rabbits.1 A pars plana cannula is connected to a vitrectomy air injector to form an intravitreal air bubble, which, after many hours, essentially fills the vitreous cavity, occludes retinal breaks, and leads to reattachment. This method may have the following advantages in patients: (1) there is direct, reliable, virtually constant occlusion of retinal breaks; (2) the number, size, and location of retinal breaks are relatively unimportant (giant tears and substantial proliferative retinopathy are contraindications); (3) there is minimal dependence on patient positioning; (4) the intraocular pressure is controlled; (5) surgery is simplified; and (6) no unapproved, nonphysiologic gases are used. We conducted a pilot study to evaluate the efficacy and safety of continuous vitreous insufflation in patients.
