[Subretinal fluid drainage in rhegmatogenous retinal detachment]. / La ponction du liquide sous rétinien dans la chirurgie du decollement de rétine rhegmatogène.

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). The complications met were retinal haemorrhages in 14 cases (7%) and retinal incarceration in one case (0.5%). Anatomical results were 91.45% in the group with drainage and 93.93% in the group without. There was no statistical difference between the two groups. The complications of the subretinal fluid drainage are extremely rare and have no repercussion if it is well checked. Subretinal fluid drainage remains the surgeon decision. It is achieved by most retinal surgeons (75%).
