[The use of expansive gas in retinal detachment complicated by vitreoretinal proliferation].

We used quantities of perfluoropropane as a substitute of vitreous in some cases of retinal detachment with vitreoretinal proliferation. It seems to be a good method compared with the injection of silicon oil for in 23 cases treated recently, the evolution of the vitreoretinal proliferation seems to have stopped better than with silicon oil. Postoperative intraocular pressure surveyance is highly advisable.
