【眼中的怪物】眼睛被14条虫侵占，她经历了什么？【郑郑得证】

what would you do if a fly was flying in front of your eyes

Some guys may wonder what's the point

You don't need to chase it away, it will fly away by itself

It would be a big mistake to think so

because there is bad news for you

Flies may spit bugs into your eyes

you heard me right

A few years ago,

a college student found that her eyes were very uncomfortable

only found after looking in the mirror

There is a small transparent line under the eyeball

In the end, it turned out to be a whole worm

Watching the worm move on the finger

it made her sick

And what made her even more unacceptable was that

The total number of bugs in her eyes is far more than these

Are your eyes a little uncomfortable seeing this?

It's okay, you'll be comfortable after watching this video

This is a useful video

Please repost it after watching it

Especially those with pets

The college student mentioned at the beginning is Abby Beckley.

she is the first person infected with rare eye worm in American history

Scientists have only found it in cattles before

summer of 2016

Abby, 28, lived in the southern ranch for a while in Oregon

She enjoyed riding a horse and fishing every day

In addition, the cattle industry there was quite famous.

but just a few weeks later

things were getting outrageous

Abby first felt something in her eye

she thought it was the eyelashes falling in,

so she didn't take it seriously.

But gradually, the uncomfortable symptoms became more obvious

Abby's eyes began to itch and sting inexplicably

no one found a foreign body in the eye either.

That's when Abby realized the eyelashes weren't the problem

The situation was definitely more serious than she thought

Finally one day she had a splitting headache

she can't wait to dig out her eyes and wash them

However, when looking at the eyelids

Abby found a foreign object

there was something like a thin thread

were move over the eyelids

What happened next was something Abby would never forget.

The thread bent and danced on her fingertips

That's a live bug.

Abby panicked

and immediately contacted the doctor

To be honest, the doctor was dubious at first.

But after checking with Abby

Sure enough, 4 more worms were taken out of the eyes.

what's more exaggerated was that

some bugs were very long

just like a paper clip

after they are taken out

they died after about 5 seconds

Soon Abby was surrounded in the hospital

as she thought of these things hanging out in the eyeballs

she felt so bad

But the doctors couldn't tell the reason

So they suggested she make an appointment of

director of Ophthalmology at Oregon Health & Science University

looking for more authoritative experts

Waiting has always been a torment, Abby started to think wildly

How many worms are there in her eyes?

Will she go blind in the future?

If a worm crawls into the brain

what should she do

Surprisingly

After experts gave Abby a thorough check

he found nothing

he even started to wonder if Abby's eyes were wrong.

it's most likely just some kind of slime

but not a bug

Experts' skepticism, however, was not without reason.

After all, nothing like this has ever happened in America.

But Abby is the "Chosen Girl"

She has an infection that has never been found in humans

Nematodes

Sure enough, after an hour

Abby's eyes felt bad again

She hastened to call an expert

They finally saw an unbelievable scene

A worm moved slowly inside the eyelid

Everyone present was stunned

Shouting frantically

"Look! It's a real bug."

Immediately afterwards, the doctors dispersed to take samples

So for the next month

Experts got 14 bugs out of Abby's eyes again

watching thin nematodes crawl across her eyeballs

That scene was shocking

Later verified by experts from the Centers for Disease Control

Abby on her way to the Oregon ranch

she infected with a parasite called "bull's eye worm" (Thelazia gulosa)

As the name suggests

This is unique to cows

And live exclusively on cow's tears

And most surprisingly

Thelazia gulosa had never infected humans before

Generally speaking

This parasite only spreads among animals

just like cats or dogs

they're also at risk of this parasite

Once infested with thelazia gulosa

it may cause vision damage or even blindness

experts pointed out

This parasite lives on the surface of a cow's eye

After mating and laying eggs

tiny larvae hatched

And various types of flies

may feed on the tears of cows

If they accidentally eat the larvae, they will spit them out

And most of them spit in the cow's other eye

or in the eyes of other animals

It just so happened that Abby encountered this extremely small probability

Flies spit larvae into her eyes

Fortunately, the experts also assured her

these uninvited guests will neither eat her brains

nor cause blindness

This gradually dispelled Abby's concerns.

If the last patient was because she went to a ranch

and got infected cuz near cows

Then the second one was caught off guard.

Because she just did the most ordinary little thing

that is morning jogging

The patient is a 68-year-old woman

She is in good shape

she often goes out for morning jogs

but from March 2018

The patient's right eye became more and more uncomfortable

She also suspected that the eyelashes fell in.

or there's sand in her eyes

So she tried to wash hereyes

But the culprit showed up soon.

A living worm was wriggling desperately

just like Abby

it's also because of flies

a month ago,

The patient went for a morning jog on a trail along the California coast

just turned a corner

she hit a swarm of flies head on

She just kept patting them

to get rid of these obstacles

then keep running

But it was just this short encounter

brought her nasty parasites

and not just one

these bugs live between her lower eyelid and eyeball day and night,

wandering around

The patient came to the hospital afterwards

After the doctor's examination, he helped her take out another bug

and retained for analytical experiments

she thought the eyes would be fine after the bug was taken out.

Instead, both eyes became inflamed.

But the doctor couldn't find any trace of the bug

The patient had to go back first

under the doctor's order

She proceeded to rinse her eyes with distilled water

check eyelids from time to time

Sure enough, when the patient looked in the mirror

she finally found the last bug

Symptoms of discomfort also disappeared

According to expert speculation

When the patient encountered a large swarm of flies

There's no way to get rid of the flies in front of you all at once

So a fly carrying a larva

accidentally put larvae in her eye

But these flies were most likely also from the nearby Carmel Valley

Because there is a large pasture there

In just two years

In the United States, two rare cases of

human infection with thelazia gulosa

Although it may be a coincidence

But it can't help but make people start to doubt

is the United States facing the zoonotic dilemma?

The answer is negative

logically speaking

general parasites are less likely to suddenly transfer hosts

not to mention the transfer from animals to humans

like oriental eyeworm

Thelazia californiensis and thelazia gulosa

are relatively rare pathogens

There are 6 stages in their life cycle

First, adults live in the conjunctival sac of the final host

Oviparous females release first stage larvae

Second, some dipteran insects like flies

will feed on the tears of the host

thereby ingesting first stage larvae

Third, larva develops during the digestion of the fly

become infective larvae

Fourth, fully developed infective larva

into the mouth of the fly

waiting for the opportunity

when flies prey on tears again

Infectious larvae take the opportunity to invade the ciliary sac of the next host

just like a cow

Finally, through the intermediate host of flies

This cycle eventually spreads to humans

If you have pets at home

you must have heard of this parasite

especially oriental eyeworm

it is a nematode parasitic in the conjunctival sac of cats and dogs

Of course it is possible to parasitize the human eye

usually, infected pets will have symptoms like reddened eyes

tearing and photophobia

If left to infect

there will also be secretions flowing out

sticking of the upper and lower eyelids causing erosions

Severe cases can also cause corneal perforation leading to blindness

If a human is infected with this nematode

varying degrees of inflammation

and obvious foreign body sensation

In severe cases, photophobia and edema will also occur

then produce conjunctivitis

So if your pets cry frequently

Eyes sometimes can't open

and it often wants to scratch eyes with paws

then it's time to pay attention

It is most likely infected with oriental eye nematode

Hurry to the hospital for treatment

For the health of pets and yourself

We still need to learn scientific feeding

and regular inspection and deworming

to eliminate flies from life

Of course,

Never abandon pets because of these small problems

it's a relatively common condition for veterinarians

Take the worm out and they'll be fine.

Also, if doing a good job of defense

and paying attention to eye hygiene,

pets will not easily be infected

their owners can also be more secure

Of course, don't worry that

your eyes are uncomfortable because you have loiasis

Think about if it spreading to the eyes of people

how many complicated processes have to go through

it's impossible that every fly eats the tears of the Euglena

and spit it into your eyes

The odds of that are lower than winning the lottery.

Both cases in the video are rare exceptions

After all, it is one of the hundreds in the United States.

they're okay in the end

it's not life threatening

Well, that's the end of this video.
