Pli maculaire compliquant la chirurgie du décollement de rétine

The formation of a macular fold after vitrectomy was probably caused by the complete fluid/gas exchange, which displaced the subretinal fluid from the periphery to the posterior pole, detaching the macula. Tangential traction exerted by the presence of intravitreal gas and subretinal fluid might have stretched the retina and resulted in the formation of the fold. This mechanism is similar to the technique used in macular translocation surgery. To avoid this complication in macula-on retinal detachment, we suggest not using perfluorocarbon liquid systematically and replacing the complete fluid/gas exchange with a limited bubble of expansive gas combined with postoperative positioning.
