[Subretinal fluid drainage in rhegmatogenous retinal detachment].

Subretinal fluid drainage during retinal surgery is a tricky manoeuver that remains controversial. In this study, we carried out a comparative retrospective study about 265 cases with retinal detachment that had a primary episcleral surgery. We compared the results of the group operated with subretinal fluid drainage (199 cases) to the group without (66 cases).
