Almost 50 people in India blinded themselves after looking directly at the sun to see an image of the Virgin Mary.
The group started staring at the sky after reports of the visions were said to have appeared over the former home of a hotel owner in the Kottayam area in southeast India.
One hospital in the district reported 48 patients had been admitted with burned retinas since last week.
Churches have warned their congregations that looking at the sun will cause permanent blindness and have told them the supposed miracle is not one.
