1, 3-year-old children have bugs in their eyes.
"Look, there is a little white bug crawling in the child's eyes!" 165438+1On October 26th, a little patient came to the ophthalmology department of daming county Maternal and Child Health Hospital. The doctor actually caught a parasitic pinworm about 1 cm from the patient's eye.
It is understood that this little patient Xiao Jian (a pseudonym) is only three years old this year. This is his second visit to the doctor. Two days ago, Dr. Zhang, an ophthalmologist, just took out a parasitic pinworm from his eye. The doctor diagnosed that the boy's poor hygiene habits led to the parasitic pinworm in his eyes.
According to Xiao Jian's parents, Xiao Jian has been rubbing his eyes in recent days. After careful examination, his parents found that there was a white "filament" swimming in his son's eyes. The frightened parents rushed their children to the ophthalmology department of daming county Maternal and Child Health Hospital. Dr. Zhang found a linear worm in the conjunctiva of the eyeball. Dr. Zhang immediately took out a bug with special tweezers, which was milky white and about 1 cm long. Pathological examination showed that this worm is a common parasite of children-pinworm.
"I've heard of bugs crawling out of my eyes before. This is the first time I've seen them." The ophthalmologist was surprised to say that this kind of situation has only been seen in books before. Enterobius vermicularis is generally parasitic in the intestinal cavity of human body. How did it get into your eyes?
After inquiry, the doctor suspected that Xiao Jian probably didn't wash his hands after defecation, and the eggs of pinworm often attached around the anus. When Xiao Jian wiped his eyes with his dirty hands covered with eggs, he brought the eggs into his eyes. After the egg grows into an adult in the eye, it swims freely in it. The pinworm parasitic in the eyes can cause conjunctivitis, which can seriously damage the optic nerve and lead to blindness.
It is understood that pinworm is the most common parasite in children, but it is often neglected, mainly because the symptoms of the disease are mild, usually manifested as anal pruritus, especially at night. Anal pruritus will appear when sleeping at night, and I feel something crawling there, which is very uncomfortable. In fact, this is caused by pinworms laying eggs in the anus. If parents find that their children often scratch their buttocks or anus, they should be alert to whether their children are infected with pinworms.
In addition, many children's eyes are easy to breed conjunctival sucking nematodes, that is, small white nematodes. They are mainly parasitic on the conjunctival sac of dogs, cats and other animals, and can also be parasitic on human eyes, causing conjunctival sucking nematodes. Because this disease is popular in Asia, it is also called "Oriental Eye Disease".
Here, the doctor specially reminds parents that they must pay attention to urging their children to develop hygienic habits such as washing their hands before and after meals, not eating cold food, and not rubbing their eyes after stroking their pets.
2. What happened to the bug in the eye?
infect
Animals such as dogs and cats are the main sources of infection.
It may be spread by fruit flies or infected by children's contact with cats and dogs.
In addition, nine live insects were taken out of Sasha's eyes from the two insects that his parents "wiped" with towels, which shocked and puzzled the family. What kind of bug is this? How did it get into the eyes of children?
Director Chen Zhijun told the reporter that this insect is called "Conjunctival Sucking Nematode", also known as "Oriental Nematode", which is a parasitic disease that is zoonotic. Its main route of transmission is Ophiopogon japonicus (this fly is a fruit fly). When Ophiopogon japonicus bites human eyes and animal eyes, it will release larvae to parasitize human eyes and animal eyes. Animals infected with this sucking nematode are mainly dogs and cats, of which dogs are the most common. If cats and dogs are infected, people may be infected by touching their own eyes after touching the secretions of cats and dogs' eyes.
According to Sasha's parents, there are no pets at home, but there are cats and dogs in the community, and the grandmother of the child also has a puppy. It is not excluded that the child is exposed to cats and dogs when playing outside; It may also be directly bitten by fruit flies, so how to infect it is still unclear.
remind
It is recommended that families with pets regularly deworm.
The baby should wash his face separately and take a bath with a towel.
There have been many cases of this kind of sucking nematode parasitic on human eyes in China. Director Chen recalled that in 2008, he also received a small patient with a sentence, and took out seven nematodes from his eyes. Experts say that in addition to this "sucking nematode", there is another kind of worm that may run out of the eye. This is a common parasite pinworm in children. Usually, they don't wash their hands after defecation. The eggs of pinworm often stick around the anus. When a child wipes his eyes with dirty hands covered with eggs, he brings the eggs into his eyes.
Experts especially remind families with pets to pay attention to personal hygiene, develop correct pet feeding methods, bathe their pets regularly, wash their hands with soap after holding them, rinse them with tap water (if possible, wash their hands with disinfectant), and regularly deworm dogs. Dogs infected with conjunctival sucking nematodes generally have no obvious manifestations, but white linear worms can be seen in the corner of their eyes when they open their eyes. People usually get sick after the fly breeding season, which is characterized by conjunctival congestion and tears.
Families with children should pay more attention to hygiene. For example, the towel for washing your baby's face should be separated from the bath towel, and the basin for washing your face should be dedicated. Avoid direct contact with eyes with hands or unclean objects; For older children, we must pay attention to urging them to develop hygienic habits such as washing their hands before and after meals and not eating cold food.
