Ben Quilter has come fifth at the two previous World Championships
Brighton's Ben Quilter has become Britain's first visually impaired judo world champion in 12 years.
The 28-year-old won gold at the the IBSA VI World Judo Championships in Turkey, beating Iran's Eigdar Habiboll in the 60kg weight category.
There were also silver medals for Coventry brothers Sam and Joe Ingram and a bronze for Lesley Reid.
Sam (-90kg) lost to Oleg Kresul of Russia while Joe (-100kg) was beaten by his Korean opponent Choi Gwanggeun.
Reid, one of only two women representing GB at the event, lost out to her Chinese opponent in the semi-finals but beat a Bulgarian for a career-best result.
Quilter told BBC Sussex: "Such a major tournament medal is a massive confidence boost coming up to the 2012 Paralympics. It stands me in good stead.
"It's slowly sinking in. Things are coming together now. It's amazing."
He added: "I'll go away from here with a lot more confidence, but also I want to improve and get even better and better, and make sure I'm even clearer top of the pile."
The Brighton Judo Club member is currently training at the British Judo Performance Institute in Dartford.
"I've had some fantastic judo coaches through my career," he said. "And everyone who has ever helped me played a massive part in where I am today."
