Brief reportRemoval of retained subfoveal perfluoro-n-octane liquid
Section snippets
Case 1
A 52-year-old man underwent retinal detachment repair in the right eye with a scleral buckling procedure. He later developed proliferative vitreoretinopathy, which required vitrectomy surgery, an inferior retinotomy, and the use of perfluorocarbon liquid. Postoperatively, he complained of a central scotoma due to retained subfoveal PFO (Figure 1). Six months after vitreoretinal surgery, he was referred to the Cole Eye Institute at the Cleveland Clinic Foundation and underwent surgical removal
Case 2
A 49-year-old man with high myopia underwent retinal reattachment surgery in the right eye, involving a scleral buckle, vitrectomy, and perfluorocarbon liquid. He later developed proliferative vitreoretinopathy, which required vitrectomy surgery, a nasal retinotomy, the use of perfluorocarbon liquid, and silicone oil. Retained subfoveal PFO was noted postoperatively. Silicone oil was removed 1 month later, at which time the subfoveal retained perfluorcarbon liquid was removed as well. A

2020, American Journal of OphthalmologyCitation Excerpt :A hole formation at the top of a subretinal bubble can lead to the passage of the bubble in the vitreous cavity,35 whereas macular bubbles result in localized retinal atrophy and death of photoreceptors.36 Given the possible functional37–39 and anatomical toxicities (e.g., retinal necrosis, macular hole, photoreceptor, RPE damages, and retinal re-detachment), techniques have been developed to remove any PFCLs remaining inclusion bubbles.35,36,40–42 Under the macula, inner retinal inclusions were found in 20.83% cases and in 16.67% cases in outer retinal inclusions in which PFO was used, whereas only 3.44% of the eyes had inner or outer retinal inclusions when perfluorodecalin was used.
Removal of subfoveal perfluorocarbon liquid: Report of 3 cases
2017, Journal of Current OphthalmologyCitation Excerpt :The advantages of perfluorocarbon liquids (PFCLs) have been widely reported in vitreoretinal surgery. However, its use is associated with some complications including the risk of PFCL retention which range between 0.9 and 11%.1–3 Subretinal retention of PFCL is thought to cause retinal damage as a consequence of mechanical compression of the retina, and secondly from chemical toxicity due to high oxygen carrying capacity of this tamponade which causes vasoconstriction of retinal blood vessels.4–7
