Sinawat and colleagues1 recently described an equivalent final reattachment rate and final visual recovery with air or gas in retinopexy. However, their discussion does not completely explain the results. Generally speaking, there seems to be some confusion with respect to the relative importance of a gas bubble's 2 properties of buoyancy and surface tension in the context of retinal detachment surgery and pneumatic retinopexy; this is worth addressing.
