Gas Injection for Retinal Detachments - Retina Specialist

Gases used are usually SF6 (sulfur hexafluoride), C2F6 (hexafluoroethane) and C3F8 (octafluoropropane). These are large molecules, are inert (don’t react with tissue) and can expand at given concentrations. Their large size means that they will be slowly absorbed after injection, giving us plenty of time to use them as a tool.
