124 c Fig. 6.14c 6 Minimal Segmental Buckling With Balloon Fig. 6.14. Balloon as late reoperation of proliferative vitreoretinopathy (PVR)-C2 detachment. a A three-quadrant detachment with PVR and starfolds in two quadrants in an eye with a previous buckle operation with diathermy and a tear anterior to the buckle at 9:00. As minimal approach for reoperation in presence of diathermized sclera, a parabulbar balloon was selected. b After balloon operation (6 months): The macula had already attached 2 days after surgery. At 6 months, a residual traction detachment with concave contours and concave surface is persisting; the macula is still attached. c After balloon operation (4 years): The traction detachment has flattened, only faint remnants of starfolds are visible All of the listed advantages can be achieved by applying a temporary and not suture-fixated balloon buckle without drainage as treatment for a primary retinal detachment. But the “conditio sine qua non” for success with this minimal procedure is experience in the non-drainage operation. The surgeon has to be an expert in indirect binocular ophthalmoscopy and has to be able to locate a balloon correctly in the parabulbar space beneath a highly detached break.
Minimal Segmental Buckling With Sponges or Balloons 125 Minimal Segmental Buckling With Sponges or Balloons Without Drainage: A Medline Analysis Materials and Methods A Medline search was made of all reports that were identified by the search terms “retinal detachment,” “segmental buckling,” “minimal extraocular surgery,” and “nondrainage.” Reports published in English, German, Italian, French, Spanish, and in some East European journals were reviewed and analyzed. The majority of reports did not contain homogenous data suitable for the analysis. Many included both complicated and uncomplicated detachments, primary detachments and reoperations, or no preoperative characteristics. In many series, primary segmental buckling was combined with a cerclage. The buckling was performed with or without drainage of subretinal fluid. <strong>Primary</strong> segmental buckling was sometimes combined with an injection of air, an expanding gas, or silicone oil. After excluding these reports, an analysis was made of a relatively homogenous series of mostly primary retinal detachments, some with preoperative PVR stage C1–C2. The primary procedure in all eyes was minimal segmental buckling without drainage of subretinal fluid. The analysis consists of five reported series with a combined total of 1,462 retinal detachments [26, 37, 39–42]. The preoperative characteristics of the 1,462 primary retinal detachments were: aphakia/pseudophakia in 8.3% and preoperative PVR stage C1–C2 in 2.9% (Table 6.1). All operations were done under local anesthesia. Coagulation was limited to the area of the break(s) and performed with intraoperative cryopexy under ophthalmoscopic control or with laser coagulation on a subsequent day after the break was attached. The buckle was limited to the area of the break(s) and was obtained with an elastic silicone sponge or a temporary balloon. Subretinal fluid was not drained in any eye. Some of the detachments treated are represented in Figs. 6.4–6.13, recruited from series 2 and 5. All patients were mobilized after
