Democratic presidential candidate Joe Biden, on Wednesday during a CNN town hall meeting on climate change gave the audience a scare. The former vice president appeared to have bursted a blood vessel in his left eye and didn’t even seem to notice.

The 76 year old had faced multiple scrutiny over his age and previous history of health complications.

The broken blood vessel in the eye, also known as a subconjuctival hemorrhage, can be caused by several things, including high blood pressure, bleeding disorders, blood thinners, or even excessive straining. (WashingtonExaminer reports)

Biden, 76, has long been plagued by health issues. In 1988, he suffered an aneurysm that burst and required him to undergo emergency surgery. The then-senator was so close to death that a Catholic priest began preparing to administer the sacrament of last rites.

Months later, surgeons clipped a second aneurysm before it burst. Biden then took a seven-month leave from the Senate following the surgery. Describing the operation, he once said, “They literally had to take the top of my head off.”

Jill Biden said in her recently released autobiography Where the Light Enters that, at the time, she feared her husband would never be the same. “Our doctor told us there was a 50-50 chance Joe wouldn’t survive surgery,” she wrote. “He also said that it was even more likely that Joe would have permanent brain damage if he survived. And if any part of his brain would be adversely affected, it would be the area that governed speech.”
