The incident occurred behind a locked gate at the Survival Outreach Sanctuary in Spring Hill, Florida, on Friday.
Sylvia Fernandez, a director of the Sanctuary, suffered a serious eye injury when she was gored by a deer.
The victim's sister called for help in a phone call to the Pasco County Sherriff's Office, explaining that Fernandez was in a recreational vehicle (RV) in the woods of north Pasco County, 'Tampa Bay Times' reported.
Fernandez was airlifted to a local hospital where she was listed in stable condition.
Gary Morse, spokesman for the Florida Fish and Wildlife Conservation Commission, said the deer was still in his enclosure at the sanctuary and the case was under investigation.
A lion had escaped for a short time last week from the sanctuary. Officers had to tranquilise the lion with a dart gun and put her in another cage.
