[Superior bullous retinal detachment: value of the intravitreous injection of sulfur hexafluoride].

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.

[Possible vascular factor in idiopathic detachment of the retina (author's transl)].

The possible influence of a vascular factor in idiopathic detachment of the retina was studied by comparing the frequency of hypertension and hyperlipidemia in groups of myopic and non-myopic subjects within the age group 50 to 65 years. Hypertension was present in 37.1 p. cent and hyperlipidemia in 60 p. cent of the non-myopic subjects, against 9.7 p. cent and 33.33 p. cent respectively in the myopic subjects. These results, together with the fact that there was a later age of onset in the non-myopic group, suggest that a vascular factor could be of etiological significance in idiopathic detachment of the retina in non-myopic subjects.
