Former WBA flyweight and ex-IBF super flyweight champion Daiki Kameda on Thursday described his boxing career as "the best" after deciding to retire because of an eye injury.

Kameda, the second eldest of the three Kameda boxing brothers, has decided to step down from the ring once and for all due to a detached retina in his left eye.

"It would have been tough to carry on with only (clear vision in) one eye. (But) I have had the best boxing career," Kameda told reporters at Narita airport after arriving home from the United States, where he had been staying for his wedding ceremony.
