Doctors in India were dumbfounded when they discovered that a 7-year-old girl wept stones, and are clueless as to what may be causing the phenomenon.
According to local newspaper Tamil Nesan, Kura Nitya from a village near Hyderabad has been discharging stones from her right eye for the past 15 days.
She has been weeping about 12 to 25 stones a day.
Her parents have approached several ophthalmologists, who were unable to diagnose what was causing the problem.
Her grandfather Gopal Reddy said that the stones began popping out on Oct 26.
"Initially, we thought it was some divine power and prayed to God for this phenomenon to stop," the Star Online quoted Reddy as saying.
They kept the stones for medical tests.
Nitya said the lower portion of her right eye swelled minutes before the stones painlessly popped out.
Ophthalmologist Dr Kalyan Chakaravarthy said Nitya was medically fit and there was no logical reason for the phenomenon.
