[Deposits of perfluoroctane after prolonged use as a post-operative vitreous substitute]

We describe a 72-year-old woman with a retinal detachment who underwent pars plana vitrectomy (PPV) and intraocular tamponade with a combination of silicone oil and perfluoro-n-octane as a postoperative vitreous tamponade. Three months later, plaque-like deposits of emulsified perfluoro-n-octane were visible on the inferior retina.

Deposits of emulsified perfluoro-n-octane, as epiretinal plaques, have not been previously been described as adverse reactions following the use of perfluorocarbons in the eye.
