title: [Superior bullous retinal detachment: value of the intravitreous injection of sulfur hexafluoride].
abstract: 15 cases of superior bullous hemi-retinal detachment were repaired during a 16-month period, with a post-operative follow-up of 3-19 months. Intravitreal injection of 0,75-1,5 cc of pure sulfur hexafluoride (SF 6) was performed in 9 cases. The indications for injection at the end of the procedure were: 1) absence of chorioretinal contact in spite of an indentation in the correct position; 2) fishmouth configuration of the retinal break; 3) presence of radial folds over an indentation parallel to the limbus. Only two out of patients required a second operation, due to the development of proliferative vitreoretinopathy. One case was unsuccessful because of a redetachment secondary to massive periretinal proliferation. No complication was observed with the injection of SF 6. In particular, ocular hypertension was avoided by controlling the amount of gas used, always inferior to 2 cc, and postoperative treatment with acetazolamide and topical timolol. The intraocular injection of SF 6 appears to be useful contribution to the surgical treatment of superior bullous hemi-retinal detachment, allowing effective and durable internal tamponade, while avoiding prolonged bedrest.
