Direct transretinal removal of subfoveal perfluorocarbon liquid combined with internal limiting membrane peeling

Abstract

A 65-year-old woman was referred to our institution with a 5-day history of visual impairment in her right eye and macula-off retinal detachment. A successful 23 G pars plana vitrectomy was performed with a 1000 cs silicone oil injection, and the silicone oil tamponade was extracted 2 months later. During the fundoscopic and optical coherence tomography examinations, three subfoveal perfluorocarbon liquid bubbles were detected, and her best corrected visual acuity was limited to 20/400. Brilliant blue staining was used for the internal limiting membrane peeling, and the direct transretinal aspiration of the perfluorocarbon liquid bubbles was performed with a 23 G silicone-tip Flute cannula. This patient’s best corrected visual acuity increased to 20/200 at the 1 month follow-up and then to 20/100 at the 1-year follow-up.

An in‐vitro study of subretinal perfluorocarbon liquid (PFCL) droplets and the physics of their retention and evacuation

“…2019; Erden et al. 2019; Falavarjani & Anvari 2019). From these publications, a total of 60 retained PFCL droplets in subretinal space were identified.…”

“…2018; Erden et al. 2019; Falavarjani & Anvari 2019). Thirdly, OCT scans might not have cut through the greatest linear diameter that may lead to underestimation of volumes.…”

Long-term Outcomes of Submacular Perfluorocarbon Liquid Removal with Internal Limiting Membrane Peeling and Transretinal Aspiration

“…The mean time of the second surgery (performed for removal of submacular PFCL) was 9.80 ± 1.17 weeks (8)(9)(10)(11)(12)(13)(14) after the primary PPV surgery. The surgeries were combined with phacoemulsification and IOL implantation for 4 phakic patients (26.67 %), and silicon oil extraction for 13 patients (86.67 %) who had silicon oil endotamponade.…”

“…Re-detachment was not observed during the follow-up time. At the end of the followup time, the mean BCVA was 0.80 ± 0.11 logMAR (1.40-0.30) [0.91 ± 0.38 logMAR (1.30-0.30) for pseudophakic patients] and the mean IOP was 13.20 ± 1.89 mmHg (10)(11)(12)(13)(14)(15)(16)(17). A significant increase in the mean BCVA was observed at the end of the followup time (p = 0.001 for all patients and p = 0.003 for pseudophakic patients).…”

“…The localization of submacular PFCL was subfoveal in nine patients (60.00 %), non-subfoveal in four patients (26.67 %), and both subfoveal and non-subfoveal in two patients (13.33 %). The mean time of submacular PFCL diagnosis was 4.86 ± 1.02 weeks (2)(3)(4)(5)(6)(7)(8) and the mean time of the surgery was 9.80 ± 1.17 weeks (8)(9)(10)(11)(12)(13)(14). Complete removal of submacular PFCL was achieved in all cases (100 %) and no significant treatment-associated complications were observed.…”
