The case began when the baby's parents brought him to a pediatrician for a well-child visit. The doctor noted the cosmetic on the child's eyelids, and tested his blood for lead. The baby was treated with iron supplements, and referred for further testing at the hospital. The baby was growing well and developing normally, according to the report.
The parents stopped using the product, and follow-up blood tests showed the boy's lead levels were dropping.
Tiro is also called "tozali" and "kwalli," and similar products called "surma" and "kajal" in Asia, and "kohl" in the Middle East, may also contain lead, the report said.
The powder has many uses as a folk remedy, the report said, including relieving eyestrain or pain, and preventing infections in a baby's umbilical cord stump or circumcision wound.
