Ryder Cup organizers are helping a spectator who said she had been blinded in one eye after being struck by a tee shot hit by American Brooks Koepka during the weekend's match against Europe, they said on Tuesday.

Corine Remande said she was unable to see out of her right eye after being hit when Koepka's drive veered wide of the fairway on the sixth hole on Friday, the opening day of the event in Paris.

"Doctors told me I had lost the use of that eye," Remande said.

Remande was treated at the course before being taken to hospital. US Open champion Koepka stopped to see how she was.

"It is distressing to hear that someone might suffer long-term consequences from a ball strike," a Ryder Cup spokesperson said.

Organizers promised to do as much as possible to help.

"We are hugely sympathetic and will do everything we can to support the spectator, insofar as that is possible under very difficult circumstances," they said in a statement.

"We have been in communication with the family involved, starting with the immediate on-course treatment and thereafter to provide support, helping with the logistics of repatriation, including providing a transfer for the family from Paris to Lyon. We will continue to offer support for as long as necessary."
