The family members of the deceased have alleged that the medicines which she was taking for heart-related ailments had to be stopped as she was put on different medication when she developed blurred vision after being injected with alleged "contaminated" medicine on April 1.
"She died of cardiac arrest late on Friday night (April 7) after her condition deteriorated," said a relative.
The GTB hospital has constituted a committee to probe the incident in which 20 eye patients had to be rushed to AIIMS from GTB Hospital last Sunday after they were allegedly administered "contaminated" injections. Eight of them had to be operated upon.
The hospital authorities had also sent the sample of the medicine and the injections to a microbiology lab for testing.

"We have sought a report from the GTB hospital into the matter. Preliminary enquiry had found that the drug used were not out of expiry dates. We are yet to receive the laboratory report," a senior health department official said.
One of the vials of the medicine -- Avastin -- administered was suspected to have been contaminated.
"Avastian is classified as a sight-saving drug and is used all over the world. Now in this case, these patients probably were given contaminated injections as they developed blurred vision accompanied with mild pain.
"Eight of them had to be operated upon to remove the infectious part of the vitreous humor, while the vision of the rest improved after primary treatment," Dr Kumar said.
