• INTRAVITREAL SULFUR HEXAFLUORIDE INJECTION FOR THE TREATMENT

    Purpose: Vitreomacular traction (VMT) syndrome can cause symptomatic metamorphopsia and decreased visual acuity. Although it is typically treated with vitrectomy or intravitreal ocriplasmin injection, these procedures can be invasive and costly. The purpose of this retrospective, consecutive case series was to evaluate the efficacy of intravitreal expansile sulfur hexafluoride gas injection for the treatment of symptomatic VMT syndrome.

    Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent man-made greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a de

  • Electric Power Systems Partnership | Fluorinated Gas

    Emission SourcesMitigation OptionsRelevant LinksFrequent QuestionsThe most common use for sf6 gas, both domestically and internationally, is as an electrical insulator in high voltage equipment that transmits and distributes electricity. Since the 1950’s, the U.S. electric power industry has used Sulfr hexafluoridein circuit breakers, gas-insulated substations and other switchgear used in the transmission system to manage the high voltages carried between generating stations and customer load centers. Several factors affect Sulfr hexafluoride emissions from electric power systems, such as the type and age of the insulating gas-containing equipment (e.g., old circuit breakers can contain up to 2,000 pounds of Sulfr hexafluoride, while modern breakers usually contain less than 100 pounds) and the handling and maintenance procedures practiced by electric utilities. Because of its long life span and high global warming potential (GWP), even a relatively small amount of sf 6can impact the climate. The electric power industry uses roughly 80 percent of all Sulfr hexafluoride produced worldwide. Ideally, none of this gas would b...
