[Extrascleral ballooning. 2. New approaches: double and sector ballooning]

Treatment of retinal detachment with the use of distended balloons (extrascleral ballooning) holds good promise due to ease of operation and low traumatism. Unfortunately it may be used only in cases with fresh not high detachments of the retina with solitary or multiple ruptures up to 1-2 optic disk diameters in length. That is why the authors suggest two new modifications of the method: double and sector ballooning, widening the indications for the employment of the method. Double ballooning is recommended for cases with retinal detachments with 2 ruptures up to 2 disc diameters in length, located at a distance of 2-3 disc diameters from each other within one quadrant or in different quadrants of the fundus oculi. Sector ballooning is recommended for cases with retinal detachments with ruptures or breaks off 3-6 disc diameters in length. The results of 24 surgeries are analyzed. Double ballooning is effective in 77 percent of cases, sector ballooning in 82 percent. The presence of proliferative vitreoretinopathy, stages C3-D, is a contraindication against the use of this technique.
