Man goes partially blind after adopted cat scratched him on the arm trends now
A man from Texas went partially blind in one eye after being scratched by his adopted pet cat.
The 47-year-old, who has not been named, was infected with bacteria that triggered inflammation in his optic nerve triggering the vision loss.
His illness started with headaches and fever a few weeks after adopting the cat, which he put down to a Covid infection. But when he suddenly lost vision in part of his left eye while driving, he rushed to the ER.
Doctors there diagnosed him with cat scratch disease, caused by the bacteria Bartonella henselae that cats can pick up from fleas. He was given a course of antibiotics and the disease subsided, with his vision returning to normal.

Cat scratch disease, also known as scratch fever or felinosis, strikes about 12,000 Americans every year according to the Cleveland Clinic.
About 40 percent of cats carry the bacteria that causes it at least once during their lives, which is normally picked up from fleas, but rarely show symptoms.
Humans, however, can catch the bacteria after being scratched and fall ill three to 14 days later, facing symptoms including swelling, fever, vision loss and exhaustion. In rare cases, it could even leave a man struggling to get an erection.
Vision loss occurs in about one to two percent of cases, when the infection leads to neuro retinitis, or inflammation of the optic nerve, disrupting vision. It is normally resolved after treatment, but in some cases can leave patients with permanent blindness.
Doctors believe the bacteria can travel to the optic nerve via the bloodstream, where it then infects cells lining blood vessels within the nerve — causing inflammation.
The case was revealed this month in the American Journal of Case Reports.
The man initially thought his symptoms — including fever, night sweats and headaches — were because the Covid infection he faced a month earlier had returned.
He started to take ibuprofen to reduce his symptoms.
But after testing negative for Covid repeatedly, he went to his doctor who suggested he might have 'post-Covid syndrome', also known as long Covid.
He was sent back home to Galveston, just outside Houston.
But on the way back he had an 'abrupt' loss of vision in his left eye, where he
