He has chosen to end his 20-year career after being a member of the team that finished fourth at London 2012.
Pollock also won bronze medals at the 2004 and 2008 Paralympic Games, a World Championships silver medal and numerous silver and bronze European Championships medals.
He said: "I started playing this game after seeing it during the 1992 Barcelona Paralympic Games and made my senior debut at the 1997 Europeans in Madrid where we won silver.
"I can leave this game knowing that during my time, GB has never been out of the top five in the world and I take a huge amount of pride saying that.
"Now is the time to finish whilst I am still at the top of my game."
