Intraocular gas dynamics after 20-gauge and 23-gauge

METHODS: A consecutive series of 290 eyes that experienced 20-gauge or 23-gauge vitrectomy with 25% sulfur hexafluoride (sf 6) gas tamponade were retrospectively reviewed. Intraocular gas bubble size on postoperative Day 1 and Gas50, the interval to dissipate to a 50% gas fill, were evaluated. RESULTS: The mean intraocular bubble size on postoperative Day 1 was 92.0 ± 8.3% in the 20-gauge PPV cases and 83.8 ± 13.7% in the 23-gauge TSV cases (P < 0.001).Get price

Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent 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 density ofGet price
