RESUMEN
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.

On a basis of a series of a 130 color photographies registered under polarized light, we have studied the respective part of mass reflexions and of diffusions on the formation of fundus images. The results show that the retina is the main centre of mass reflexions which disappear in polarized light. The pigment (hemoglobin, melanin, etc...) become the main factors of the formation of fundus images. We conclude on the risks of errors which can be done by extrapolating the informations given by photography to assess the action of photocoagulation.
