When Greg Szymanski started raising money for eye research, he decided not to give it to a foundation far away. He donated the money to the lab of Dr. David Gamm, a UW-Madison retina specialist using stem cells to better understand and treat vision loss. “I wanted to help right here, where we have specialists who work on these diseases,” said Szymanski, 62, of Madison, who lost most of his sight seven years ago. Unlike government grants that pay for most medical research, Szymanski?s money comes with few restrictions, Gamm said.
