Purpose: To describe two surgical techniques for rescuing a retained heavy silicone oil bubble in the posterior pole: 1) light pipe method and 2) perfluorocarbon liquid method.
Methods: The surgical techniques are described in detail, along with an illustrative video for each.
Results: A short 25-gauge metallic cannula and active suction pump are used for standard heavy silicone oil removal. Both surgical approaches are practical and effective options to complete the removal of heavy silicone oil when a bubble sinks to the posterior pole.
Conclusion: Both the light pipe and perfluorocarbon methods are suitable to remove retained heavy silicone oil and thus avoid the need for further incisions and the risks associated with the use of larger gauge instrumentation.

Purpose: To evaluate outcomes of ultracomplex retinal detachment (UCRD) repairs performed at a large county hospital.
Materials And Methods: Retrospective chart review of patients who underwent a UCRD repair, defined as a funnel retinal detachment (RD), RD associated with ocular trauma, or RD requiring retinectomy, 5000 centistoke silicone oil or perfluorocarbon heavy liquid (PFO). The outcomes examined were visual acuity (VA), anatomic success, and phthisis development.

Solar interfacial evaporation (SIE) has emerged as a highly promising approach for sustainable freshwater harvesting. However, maintaining a stable evaporation rate and achieving a high freshwater yield in high-salinity brines remain a significant challenge. In this study, we present the development of silicone sponge-based evaporators with a "free-salt" structure, designed to enhance the efficiency of SIE and freshwater collection.

The number of patients requiring breast reconstruction with artificial implants has been increasing, and so is the use of carbon-ion radiotherapy (CIRT). Consequently, a growing number of patients with artificial breast implants are expected to undergo CIRT. Because artificial breasts are composed of a silicone polymer gel with a silicon-oxygen backbone, which differs significantly from human tissues, the stopping power ratio for carbon beams cannot be accurately converted from CT values using standard CT-to-stopping power ratio tables (CT-SP tables).

Article Synopsis
- Silicone oil (SO) is commonly used as a vitreous tamponade, but it has known complications, including glaucoma and cataracts, along with increasing cases of unexplained visual loss after SO removal.
- A literature review highlights the chemical properties of SO, its surgical complications, and issues like SO migration and proliferative vitreoretinopathy.
- Doctors must weigh the severity of retinal diseases and their own experience when choosing SO, while the search for safer vitreous substitutes remains critical.
