The removal of brain-eating tapeworms

At first, Sam thought he saw something that looked black stripes moving from left to right in his eyeballs. Finally, he realized the black line was a tapeworm, which was making a nest in his left eye.

Merck's Manual of Diagnosis and Therapy reports, the tapeworm infections experienced by Sam.
.
"Taenia solium (taeniasis) is an adult tapeworm infection due to consumption of contaminated pork," the report said, according to the International Business Times, Thursday (15/2/2018).
.
Tapeworms enter the human body when a person consumes raw pork or human contact with contaminated feces. Ribbonworms rarely enter the human bloodstream, then lodged in the brain or the eyeball of a person.

However, in Sam's case, tapeworms lodged in the vitreous part of the eye, which is the area in the fluid-filled eyes behind the cornea of ​​the eye.

Don Perez of Tampa General Hospital reveals, a brain-eating tapeworm that enters Sam's eyes through a blood vessel.
.
"The tapeworm goes into the eye through arterial blood vessels as well as veins," Perez said.

He added, the most frightening bad impact of tapeworm infections in the eyes of potentially damaging the brain. If the worm reaches the brain, the tapeworm will feed the brain up to the central nervous system.

Sam had to get rid of the tapeworm before his eyes were blind. The operation to remove the worms from Sam's eyes was quite difficult.

When the doctor released a 0.3 cm long tapeworm from Sam's eyes. The tapeworm turned out to fertilize tens of thousands of eggs.

If the tapeworm lives longer and releases the larvae into Sam's eyes. Some worm larvae will find a path to Sam's brain.
