Perfluorocarbon Liquid Tamponade Research Articles

Анализ результатов витрэктомии с эндотампонадой витреальной полости воздухом, ПФОС и эндолазерной коагуляцией ретинальных разрывов в хирургии отслойки сетчатки

The results of rhegmatogenous retinal detachment (RRD) surgery in 233 patients (233 eyes) without silicone oil application were analyzed. The first group included 76 patients (76 eyes) after vitrectomy with vitreous cavity air endotamponade and retinal tears endolasercoagulation. The second group consisted of 157 patients (157 eyes) after vitrectomy with vitreous cavity perfluorocarbon liquid (PFCL) endotamponade, endolasercoagulation of retinal tears followed by PFCL removal or replacement with air. Results. Similar comparable results were received postoperatively. Conclusion. Vitrectomy with vitreous cavity air endotamponade allows to perform effective surgical treatment of subtotal retinal detachment in case of upper retinal tears localization, and PFCL tamponade – in case of both upper and lower retinal tears localization with subsequent endolaser coagulation, and also to exclude cases with secondary glaucoma development.

Intraoperative Perfluorocarbon Liquid Tamponade Technique for Treatment of Extensive Retinal Detachment Secondary to a Myopic Macular Hole.

To report an intraoperative perfluorocarbon liquid (PFCL) tamponade technique in treating extensive retinal detachment secondary to a myopic macular hole (MH) through pars plana vitrectomy. The technique was applied in nine eyes with MH-RD extending two quadrants or more areas. The procedures for pars plana vitrectomy included: 1). thorough drainage of subretinal fluid through the MH with fluid-air exchange; 2). PFCL tamponade on the macular area for more than 10 minutes; and 3). repairing the MH after PFCL was removed. All nine eyes gained intraoperative retinal reattachment after PFCL tamponade for 22.22 ± 8.01 minutes and removal of PFCL. Procedures for MH closure included internal limiting membrane peeling in eight eyes, with internal limiting membrane free flap insertion (four eyes), internal limiting membrane inverted flap insertion (two eyes), or lens capsular flap transplantation (three eyes). All eyes received C3F8 tamponade. During 9.11 ± 3.89 months of follow-up, eight of the nine eyes (89%) achieved retinal reattachment and MH closure; one eye achieved anatomical success after reoperations. All eyes had vision improvement at the last follow-up. This new technique in pars plana vitrectomy may promote anatomical and functional recovery in the treatment of extensive retinal detachment secondary to a myopic MH.

Outcomes of a postoperative perfluorocarbon liquid tamponade for complex retinal detachments: 12\u2009years of experience in southern Thailand

BackgroundThe study evaluates both functional and anatomical outcomes of retinal detachment (RD) repair by vitrectomy and perfluorocarbon liquid (PFCL) tamponade.MethodsA retrospective chart review of patients who underwent vitrectomy using PFCL tamponade for RD repair from causes such as giant tear, chronic RD, or RD with previously failed surgery.ResultsThis study included 122 eyes from 121 patients. One-hundred fourteen eyes (93.5%) had baseline vision worse than 20/200. The median duration of intraocular PFCL retainment was 14 days before gas or silicone oil replacement. The retinal reattachment rate was 80.3%. At 1 year, the retention probability of retinal reattachment was 0.84 (95% confidence interval, 0.77–0.91). Although visual improvement was found in 45.9% of patients, the median of final vision was not different between baseline and the last visit.ConclusionThe rate of retinal reattachment operated with a short- to medium-term PFCL tamponade achieved a high satisfaction rate. However, postoperative hypotony was a predictor for unfavorable visual and anatomical outcomes.

Massive subretinal and subretinal pigment epithelial hemorrhage displacement with perfluorocarbon liquid using a two-step vitrectomy technique.

The purpose of this study was to evaluate the efficacy and visual outcome of massive submacular hemorrhage (SMH) displacement with a planned two-step pars plana vitrectomy (PPV) using tissue plasminogen activator (tPA) and perfluorocarbon liquid (PFCL) tamponade. A retrospective case series of patients with age related macular degeneration and SMH was used. All patients underwent a 23G PPV, subretinal tPA injection and a medium term PFCL tamponade. A second stage PPV for PFCL removal was performed 7-17 days later. The main outcome was the change in macular and sub-RPE thickness after 6 months. Secondary outcomes were visual acuity and complications. Seven patients (seven eyes) with mean age of 79.85 years were enrolled. The average SMH size was 17.5 disc area (range 4.5-33) with mean symptoms of a duration of 9.5 days (range: 2-21). SMH was successfully displaced in six eyes. Mean macular and sub-RPE thickness decreased from 1505μ to 711.3μ and 900 μ to 457μ, respectively. Visual acuity (VA) remained stable in five eyes. Complications included corneal edema and transient intraocular pressure elevation in three patients. SMH displacement using subretinal tPA injection and medium term PFCL tamponade is an effective alternative treatment option. In our experience, it can be safely performed, avoiding complications commonly attributed to other techniques.
