[Hemorrhage in the vitreous and retinal venous loop in a diabetic subject].

A vitrectomy was performed in a diabetic patient because of unilateral vitreous hemorrhage, which persisted for six months. There was only background retinopathy in the other eye. In the operated eye, no proliferative retinopathy was found.

[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.
