Besides, this patient still has a lot of trouble.

For example...How does the cymbidium infect the eyes?

In clinical practice, the infection of the tube round nematode is rare. Apart from a opening battle in Guangdong Province, the safety of the Fushou Snail has entered the public's view for the first time. After that, the infection of the tube round nematode caused by the Fushou Snail is rare, almost all

Said it disappeared.

There are even fewer insects in the eyes.

No one present had any experience in how to deal with parasites in the eyes.

"Why does it enter the eye? Is it directly into the eye or from other ways?" asked the ophthalmologist.

His expression was very solemn... Different ways of seeing also represent different treatment methods. The source of the intraocular nematode determines the final solution.

However, now, they don’t even understand how the cymbidium worms enter the eye...

Everyone's eyes fell back to Xu Qiu again.

Thighs, thighs... Although they didn't say anything, the words were revealed in the eyes of many directors.

Xu Qiu didn't say much and said directly: "At present, there are three main ways.

"The first is that the third stage larvae did not enter the brain, but entered the eyes directly, and then developed into the fourth stage and fifth stage larvae in the eyes.

"The second is to develop into stage 5 larvae in the brain, and then enter the eyes through the central retinal artery, or from the vortex vein and ciliary artery.

"The last possible path is somewhat similar to the second one. After the brain develops into a fifth stage larvae, the insect body moves along the surface of the cranial brain and enters the base of the skull, and then sneaks in the meningeal space of the optic nerve, gradually

Arrive at the posterior pole of the eye and then pass through the scleral sieve plate into the eye; of course there is another road, which is to reach the posterior pole of the eye and continue to crawl along the eyeball, and enter the eyeball from the edge of the sclera!”

Xu Qiu analyzed slowly.

The three ways are the main possibility of cymbidium worms entering the eyes.

The second method is the least probable.

Because the diameter of the insect body is still too large compared to the tiny eye blood vessels, they are unlikely to enter the tiny eye blood vessels.

In addition, the insect body does not have much penetration ability, so it is difficult to directly enter various blood vessels.

The greater possibility is that the third stage larvae enters the eye; or reach the base of the skull and then enters the brain indirectly.

The two approaches correspond to different treatment methods.

If it is the former, it is the easiest way to just take out the insect body from the incision of the cornea.

But the latter...the situation is much more complicated.

Since the insect body passes too many places in the middle, swimming will cause a series of inflammatory reactions, simple removal does not necessarily work, and more thorough removal is often required.

"If you want to confirm this, just look at whether the insect body is in the anterior chamber or the vitreous body, and under the retina." Xu Qiu said.

The first pathway of insects often only stay in the anterior chamber, the back of the eyes and other parts.

But the transition from the base of the skull is much deeper, and it often passes through the scleral sieve into the eyes...

"The insect body is under the retina, and the vitreous body is also turbid!" The ophthalmologist immediately remembered Xiaojie's examination results.

The vitreous body is mildly turbid, and there is a white elongate nematode under the retina at the posterior part of the equator above the temporal... According to Xu Qiu, this is definitely a third way to enter the eye.

In other words, vitreal surgery removal with a higher risk factor must be performed.

"My understanding of cymbidium worms is still in the era of local condensation..." The ophthalmologist did not expect it.

The infection of the worm is an ordinary doctor who never encounters it once in his life, and the insect body enters the eyes even more scarce, so few doctors go back to learn about the latest guidelines.

Previous treatment methods were localized after transscleral positioning, thermal coagulation or photocoagulation, and then the sclera choroid was cut or attracted to remove the insect body.

This method has great disadvantages, such as low accuracy in positioning and the possibility of serious tissue trauma, so it has been controversial.

But despite this, it has been used.

It's really because there is no better way in clinical practice.

However, now, another vitreous surgery has appeared!

The ophthalmologist couldn't help but feel a little anxious and asked, "Doctor Xu, can you tell me how to do this surgery?"

"Can."

It just so happened that all departments should cooperate, so I treated it as being familiar with the surgical plan in advance... Xu Qiu agreed immediately and began to explain.

"Viral surgery is actually a therapy based on vitreous surgery.

"This surgery is a closed three-incision vitreous cutting surgery. It is mainly used for the resection of vitreous, retinal and subretinal lesions. It is precisely because it can penetrate deep into the fundus of the eyes and can be used for the removal of worm body of the worm nematode.

"This surgery can not only remove the insect body intact, but also reduce the specific protein reaction caused by the insect body's death and fragmentation. At the same time, if there is a lesion in the patient's vitreous body, it can be synchronized.

"In addition, there are advantages such as restoring the transparency of the refractive interstitial mass and reducing the occurrence of traction retinal detachment..."

“…”

Hearing these introductions, the ophthalmologist swallowed.

So... this kind of surgery can not only be used for infections that enter the eyes of the cysticercariae, but also on cysticercariae in the eyes?

In other words, all diseases that enter the eyes of parasites can be removed through the same surgery!

Xu Qiu gave a positive answer: "In theory, this is the case. The parasites in the anterior chamber enter the anterior chamber through a tunnel incision on the cornea, and then viscoelastic is injected behind the insect body, and gradually push or suck it out.

In the worm body; parasites under the conjunctiva can directly cut the conjunctiva to get impulse; in the vitreous and subretinal, three-incision minimally invasive surgery is used.”

"I feel that after this operation with Dr. Xu, the parasites in our hospital's eyes will bloom..." The ophthalmologist sighed.

"It's finally your turn to ophthalmology." Director Lin of the brain surgery department looked like I was invincible and you were casual.

The others in the conference room suddenly glared.

With Dr. Xu’s favor, brain surgery has become one of the signatures of medical doctors, and has won the second national brain surgery center... Now it is still installed!

It seems to beat Director Lin!

Feeling the bad gaze around him, Director Lin quickly retracted his neck and changed the topic: "The eye insect body has already thought of countermeasures, and there are other aspects, such as the lesions in the brain and intestinal ducts..."

Hearing this, everyone's expressions became solemn again.

Xiaojie’s problem is not just intraocular parasites.
