Graph showing macular hole closure and type of intraocular tamponade with different concentrations of gas. The percentage of eyes with successful MH closure was higher in the eyes treated with Perfluoropropane (C3F8) 12-14 %, 15-16 %, and 22-26 % Sulfur hexafluoride (SF6) compared with eyes treated with Sulfur hexafluoride (SF6) at 18-20 %
