[Prevention of retinal detachment in massive endovitreous hemorrhage 1a].

We have made a prophylaxis of retinal detachment resulting from massive endovitreous hemorrage by applying a silicone encirclement on rabbit eyeballs in which we have previously injected autologous blood. Because of the opacity of the means echography has shown us the moment of intervening. Retinal detachment has taken place in the 64,28% of cases, against the 91,3% of a previous experience of ours in which we made no prophylactic.
