[Principles of qualifying retinal detachment for pneumoretinopexy]

The gases SF6 and C2F6 were used in 88 patients (88 eyes) with retinal detachment as endotamponade. Eighty eight patients constituted 3 groups in which the gas was used on the basis of following indications: 1) the eyes with retinal detachment from above and with holes between 9-12-3 or with a macular hole; 2) eyes with retinal detachment "without hole" or with a hole for evaluation for its size and localization, as an intervention preceding an extrascleral invagination; 3) eyes with retinal detachment from above in which after extrascleral indentation in spite of a good localization the retina did not reappose. On the basis of the presented material the authors emphasize the values of the pneumoretinopexy as a solitary procedure, a diagnostic procedure or completing an extrascleral indentation. The perils of this method are presented and the causes of failures discussed.
