  • 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.

  • Electric Power Systems Partnership | Fluorinated Gas

    Emission SourcesMitigation OptionsRelevant LinksFrequent QuestionsThe most common use for SF6, 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 SF6in 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 SF6 emissions from electric power systems, such as the type and age of the SF6-containing equipment (e.g., old circuit breakers can contain up to 2,000 pounds of SF6, 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 SF6can impact the climate. The electric power industry uses roughly 80 percent of all SF6 produced worldwide. Ideally, none of this gas would b...
