Subretinal perfluoro-N-octane (PFO) bubbles

Subretinal perfluoro-N-octane (PFO) bubbles

Category(ies): Retina
Contributor: Jesse Vislisel, MD

67-year-old male with subretinal perfluoro-N-octane (PFO) bubbles after incomplete PFO removal during retinal detachment repair at an outside facility. The patient was symptomatic with decreased visual acuity, metamorphopsias, and small central and paracentral scotomata. PFO is a heavy liquid used to flatten the retina during vitreoretinal surgery, and it should be removed intraoperatively to prevent subretinal migration.
