“…Only few studies are focused on inferior retinal breaks and inferior PVR which are at the moment the most difficult to treat. The success rate in this specific subgroup varies from 50% [19] to 78% [7]. With silicone oil, successful retinal reattachment can be achieved from 30% [18] to 75% [20].…”

“…So far no randomized clinical trial on the efficacy of heavier than water endotamponades exists for retinal detachments with inferior tears and inferior PVR. The success rate is lying between 50% (FsiO/silicone oil mixture [19]), 77% (fluorosilicone oil [21]), 78% (F 6 H 8 [7]), 86% (F 6 H 8 [22]) and 100% (perfluoroperhydrophenanthrene [23]). This wide discrepancy is mainly due to the fact that many authors assume as end-point criteria partial retinal reattachment, including eyes with endotamponade still filling the vitreous chamber.…”

Aim: To report on the use of a combined intra-ocular tamponade with silicone oil and perfluorohexyloctane (F₆H₈) in the treatment of complex retinal detachment. Design: A prospective consecutive interventional case series from seven study centres. Participants: 69 patients presenting a retinal detachment with proliferative vitreoretinopathy (PVR) and retinal breaks of the inferior two quadrants of the fundus. Method: Patients were divided into two groups: (1) 28 eyes which had not been operated on before; (2) 41 eyes affected by recurrent retinal detachment that had had unsuccessful previous surgery with silicone oil or gas tamponade. A pars plana vitrectomy, membrane peeling and – when necessary – a retinotomy were performed; the vitreous cavity was filled with two thirds of F₆H₈ and one third of silicone oil 1,000 mPas (double filling, DF). The endotamponade was removed after 30–45 days (median 38) and replaced by balanced salt solution or silicone oil according to the condition of the retina. Results: Retinal reattachment was achieved in 52 out of 69 cases (75%) 6 months after removal of the DF without any endotamponade. Conclusion: The DF with F₆H₈ and silicone oil allows a good endotamponading to the inferior retina and the posterior pole. The DF appeared to be well tolerated. Further studies are necessary to evaluate whether a DF is advantageous in respect to silicone oil filling alone in case of retinal breaks and PVR of the inferior retina.

“…Many series also include patients with previous blunt and penetrating eye trauma. 6,[12][13][14]20,25,32,34,48 This has to be kept in mind when evaluating the postoperative complications following heavy tamponades. Patients with RRD not complicated by PVR mainly consist of those with breaks or tears in the lower fundus periphery.…”

Background Heavier than water intraocular tamponades have several theoretical advantages over conventional tamponades, especially in the treatment of complicated retinal detachments and proliferative viteroretinopathy of the lower fundus periphery. However, initial clinical series of various heavy tamponades have reported significant complication rates. Therefore, heavy tamponades have not found widespread acceptance. Three recently developed heavy silicone oil tamponades, Oxane HD, Densiron 68, and HWS 46-3000, are much better tolerated and presently seem to enter routine clinical practice. Materials and methods Literature review of 21 publications on the clinical application of 9 different heavy tamponades (fluorosilicone, C10F18, F6H8, OL62HV, Oxane HD, O62, F6H8-silicone oil mixture, Densiron 68, and HWS 46-3000). Results The first generation (fluorinated silicone and perfluorocarbon liquids) and second generation (partially fluorinated alkanes) of heavy tamponades were associated with relatively high complication rates, for example, tamponade emulsification, intraocular inflammation, and rise in intraocular pressure. The complication spectrum of the new generation of heavy silicone oils (Oxane HD, Densiron 68, and HWS 46-3000) seems to be comparable to conventional silicone oil tamponades while providing better support for the inferior retina and the posterior pole. Conclusion The recently developed heavy silicone oil tamponades are safe and effective tools for the use of complicated retinal detachments of the inferior fundus.

“…The reproliferation occurred especially along a tamponade-free horizontal line involving the Heavy silicone oil D Tognetto et al posterior pole and corresponding to the interface between the two bubbles. 16,43 The combination of FALK and silicone oil could result in a single-bubble optically clear mixture, according to the proportions of the two components. This would provide a real 'heavy silicone oil'.…”

Aim To study the solubility of perfluorohexyloctane (F6H8) in silicone oil (polydimethylsiloxane (PDMS) 1000) and to measure the viscosity and the specific gravity of the mixture obtained (heavy silicone oil or HSO tamponade) to define the ideal ratio of these components. Methods The solubility diagram of the mixture was obtained with the turbidimetric method, indicating the miscibility of F6H8 and silicone oil 1000 at all the useful temperatures. The viscosity was measured in steady shear conditions by using a controlled stress rheometer (Haake RS150) and a double cone/plate (DC 60/4) system, both at 25 and 371C for different volume per cent compositions of the mixture. The specific gravity was measured at 371C using a digital densimeter. Results A mixture of F6H8 30 v% and PDMS 70 v% was found to be transparent and stable at all the useful temperatures. By combining these proportions of the two substances, a resultant density of 1.06 g/cm 3 was obtained. The viscosity of the 30% F6H8 mixture was 203 mPa.s at 251C and 163 mPa.s at 371C respectively. Conclusions The ideal F6H8 and silicone oil mixture can be obtained combining 30% of F6H8 with 70% of silicone oil 1000. This mixture seems to have rheological properties useful for its use as an alternative intraocular heavy tamponade.
