Dr. William Schaffner, an infectious diseases specialists at Vanderbilt University, said contracting a flesh-eating disease at all is rare, let alone in the eye.
"[It's] one in a million," he told BuzzFeed News, later adding he has never personally seen a flesh-eating disease infection that affected the eye, but that it's possible.
Another expert, Dr. Anne Sumers, told BuzzFeed News she thinks it is much more likely Williams suffered a corneal ulcer than a flesh-eating bacteria in her eye.
"(Flesh-eating bacteria) is very uncommon and indeed rarely reported in the medical journals. One study from two major medical centers only noted seven cases," said Sumers, who is the clinical spokesperson for the American Academy of Ophthalmology.
