"I first noticed an issue with my eyes when I was playing football. One match the ball was coming through the air and I just couldn't judge where it would land," he told BBC Sport Wales.
"That's when I knew something was wrong, I had to go off the pitch. Since then it has only got worse.
"It is like being constantly drunk. I have drunk vision, I have a drunk walk and I can't walk straight, my balance is off and now I need to have more tests and find out exactly what is wrong."
Pryce says as his eye sight deteriorated, the fear of what could happen increased in the 24 hours before a fight and especially once he stepped through the ropes.
"In the last few years I was just going in trying to not get hurt and to get out safely; I knew I was going to lose," Pryce explained.
"But I've been boxing so long, it's all I've known how to do. That's why I carried on.
"I knew with my eyes it was extra risk, but it's all I know. I started boxing when I was nine or 10, I left school with no qualifications and I started boxing professionally when I was 18.
"I got into my 30s and boxing is all I know. I knew it was a risk, but it was a risk I was willing to take.
"People told me I shouldn't be boxing anymore, but I continued anyway.
