Mini Tvaska of St. Petersburg, who holds the record for consecutive participation in the tournament, said she will participate in this year's May 21 event in Reno despite most of her vision being taken by macular degeneration, the Tampa Bay (Fla.) Times reported Monday.
Tvaska said she throws her first ball without assistance, but then needs to be told which pins are still standing so she can attempt to aim her second throw.]
She said she was initially frustrated when losing her sight.
"It was but now I'm grateful for what I can see. I do the best I can," she said.
Matt Cannizzaro, media relations manager for the USBC Open and Women's Championships, said officials are proud to have Tvaska as an annual competitor.
"Mini has displayed admirable dedication to the sport of bowling, and we're glad to have her as a representative," he said. "She lights up the event as soon as she walks in."
