Abstract Details


the aim of this poster is to illustrate a case of significant and stable visual function in a patient with retained subfoveal perfluorodecalin after 20-gauge primary pars plana vitrectomy, air-perfluorodecalin exchange, 360° endolaser photocoagulation and injection of 20% sulfur hexafluoride in the vitreous cavity for a spontaneous rhegmatogenous macula-off retinal detachment.


most reports showed retained subretinal perfluorocarbon liquid (PFCL) causing underlying retinal pigment epithelium atrophy, very poor central vision and, in a few cases, permanent absolute scotoma but one case report showed visual acuity (VA) of 20/40 despite 10 years of retained subfoveal PFCL.


VA and spectral domain optical coherence tomography (SD-OCT) were performed at day 7, day 15, month 1, 2, 7, 12 and 18 in left eye after vitreoretinal surgery.


SD-OCT testing revealed a subfoveal PFCL droplet detected as a subretinal foveal hyporeflective area stable in dimensions and position from day 15 to month 18 after surgery. Initial VA was finger counting, before and at day 15 after surgery, progressively increasing up to 20/64 ETDRS chart at month 12 after surgery and remaining stable until month 18 after surgery.


the patient achieved a partial and stable recovery of VA despite the constant position and dimensions of foveal retained subretinal PFCL during 18 months after vitreoretinal surgery.
