Aim: To evaluate the importance and benefits of using gases in vitreoretinal surgery. Material and Methods: The gases represent a wide group of substances used in eye surgery for more than 100 years. The role of intraocular gases in vitreoretinal surgery is irreplaceable. Their use is still considered to be the “gold standard”. An important step in eye surgery was the introduction of expanding gas...
