title: [Silicone sponges rejection (author's transl)].
abstract: Out of 633 retinal tears or detachments treated by cryocoagulation and Lincoff sponges without scleral dissection, our rate of sponge rejection is 8 per cent (51 out of 633). Out of these 51 rejections we have 4 spontaneous expulsions and 45 surgical removals. In 2 cases we could preserve the buckle by medical treatment. The most pre-eminent causes are in decreasing frequency: --the peroperative sponge infection, mostly by staphylococcus epidermidis, --the existence of an anterior positioned sponge, more than a quadrant long, factor of bad mechanical tolerance, --several operations. The rate of anatomical success is of 86% in this group of 51 patients (80% if we only number successes at six months). We have had 8 recurrences after sponge removals (15%). Recurrences are due to sponge infection; they are mainly due to the reopening of the primitive lesions (6 times out of 8). Only 5 recurrences have been cured (62,5%). This result seems, however, better than the one reached by authors using scleral dissection techniques; according to us this is due to the relatively rare severe vitreous reactions when episcleral sponges' infection occurs.
