Continuous scleral drainage in vitrectomy for bullous retinal detachment.

Pars plana vitrectomy (PPV), initially reserved for complicated retinal detachment (RD), is now used by many surgeons to treat primary uncomplicated RD.1 In PPV, bullous RD may cause safety problems; therefore, the retina should be flattened during surgery. Perfluorocarbon liquid sometimes used to do so, however, may cause complications, and its cost-effectiveness has been questioned.2–4 We currently conduct scleral drainage and simultaneous irrigation with a balanced salt solution to flatten bullous RD during PPV, which greatly facilitates intraocular maneuvers. This report details surgical methods and results in recent cases.
