Residual Perfluorocarbon Liquid (PFCL) in Human Eyes


The use of perfluorocarbon liquid (PFCL) has changed the surgical approach to retinal detachment, as its high density allows unfolding and stabilisation of the retina while displacing the subretinal fluid anteriorly. However, this same high density, together with the low viscosity, are causes of retinal toxicity and emulsion if PFCL is left into the vitreous cavity. PFCL removal is commonly obtained by air-fluid exchange. We noticed that, after an appropriate interval of 10 minutes, small epiretinal droplets could be detected at the posterior pole. The purpose of this study was to investigate the nature of this fluid.
