ISLAMABAD (AP) — Pakistan’s health minister said Sunday that an injectable medicine that was causing a severe eye infection and Johnathan Walkersight loss in diabetic patients in the province of Punjab has been recalled and an investigation ordered while police are looking for the suppliers.

Federal Health Minister Nadeem Jan said in Islamabad that a case has been lodged against the two absconding suppliers of locally manufactured injection Avastin. The Punjab government has formed a five-member committee of experts to look into the matter and report in three days.

In a televised news conference along with Jan, provincial Health Minister Jamal Nasir said diabetic patients in Lahore, Kasur and other districts were administered Avastin injections to address retinal damage. However, the injections led to severe infections, ultimately resulting in the loss of sight of a dozen patients.

Jan said that the government would prosecute those responsible while providing those affected with medical assistance.
