Vitreous swine cysticercosis
Introduction
Introduction to vitreous cysticercosis Cysticercus cellulosae of the cysticercosis with the blood flow through the choroidal blood vessels into the retina, and then into the vitreous, forming vitreous porcine cysticercosis (cysticercuscellulosae), more common, the path of the disease is due to the patient's ingestion containing unkilled mites After the egg's pork, the outer shell of the aphid egg is digested by the duodenal juice, and the six-hook aphid drills into the intestinal wall and spreads with the blood circulation to form a cysticercus in the tissue. The cysticercosis can parasitize any part of the eye. Among them, the most common in the vitreous. The path of the disease is caused by the patient ingesting the pork containing the unkilled aphid eggs. The outer shell of the aphid eggs is digested by the duodenal juice, and the six hookworms are drilled into the intestinal wall and spread throughout the body with the blood circulation. And form cysticercosis. basic knowledge The proportion of sickness: 0.0001% - 0.0002% Susceptible people: no specific people Mode of infection: non-infectious Complications: vitreous opacity, retinal detachment
Cause
Causes of vitreous porcine cysticercosis
Cause:
The path of the disease is caused by the patient ingesting the pork containing the unkilled aphid eggs. The outer shell of the aphid eggs is digested by the duodenal juice, and the six hookworms are drilled into the intestinal wall and spread throughout the body with the blood circulation. And form cysticercosis.
Prevention
Vitreous cysticercosis prevention
1. The treatment of patients on the basis of the census on time for the patient's deworming treatment, because the parasites in the intestines can often lead to cysticercosis, it must be treated as soon as possible and completely deworming, more mites and drugs, in recent years, more areca nuts and pumpkin seeds Mixture, in addition, adipine, praziquantel, mebendazole, albendazole, etc. have achieved good deworming effect, betel nut, pumpkin seed mixture therapy is effective, most patients discharge completely within 5 to 6 hours of taking the drug In the case of worm body, if only part of the worm body is discharged, use warm water to bathe, let the worm body slowly discharge, do not pull hard, so as to prevent the anterior segment and head section of the worm from being left in the digestive tract, and the used water should be properly treated. In order to avoid the spread of eggs, take 24 hours of feces after taking the medicine, carefully wash and check for head joints. If the head section is not obtained, follow-up should be strengthened. If no sections or eggs are found within 3 to 4 months, As a cure, the method of treating cysticercosis is to remove cysticercosis by surgery. The only reasonable treatment for cysticercosis is surgical removal of the worm, such as death of the worm, causing severe inflammatory reaction. Recently, it has to be removed. whole Eyeballs, but cysts in the special parts or deeper are often difficult to perform surgery, but can only give symptomatic treatment, such as anti-epileptic drugs when cerebral cysticercosis, domestic useful Chinese medicine and acupuncture treatment of cysticercosis In recent years, it has been proved that praziquantel, albendazole and mebendazole can degenerate and die of cysticercosis, especially the former has the advantages of high curative effect, small dose and convenient administration, but has different degrees of headache, vomiting and fever. Dizziness, rash and other toxic side effects.
2. Manage the toilet pigsty to mobilize the masses to manage the toilets, build pigs in the circle, and control the infection between humans and animals.
3. Attention to personal hygiene must vigorously promote the harmfulness of the disease, remove bad habits, do not eat raw meat, wash hands before and after meals, in order to prevent accidental consumption of eggs, cooking must be cooked meat, the cysticercosis in the meat at 54 ° C by 5 It can be killed in minutes, and the chopped meat knives and cutting boards should be separated.
Complication
Vitreous porcine cysticercosis complications Complications vitreous opacity
Due to the vitreous opacity, it is not easy to see the typical morphology of cysticercosis, and complications such as retinal detachment may occur. Sometimes cysticercosis can penetrate into the retina and parasitize.
Symptom
Symptoms of Vitreous Cysticercosis Symptoms Symptoms of vitreous retinal detachment in the vitreous sac
1. Symptoms: In the early stage, there are oval black shadows and telescopic deformation, creeping shadows, and late vision due to interference and inflammation in the tissues of the eye. Visual acuity can be significantly reduced or even blind.
2, fundus examination: visible in the vitreous yellow-white translucent circular vesicles, about 2 ~ 6PD size, surrounded by a golden yellow reflective ring, visible bright white white plus punctate head, can be caused by strong light The head is telescopic, and sometimes the suction cup can be seen in the telescopic head.

Examine
Examination of vitreous porcine cysticercosis
Fundus examination: visible yellow-white translucent round vesicles in the vitreous, about 2 ~ 6PD, surrounded by golden yellow reflective circles, visible bright white and punctate head in vesicles, can cause head when illuminated by strong light Telescopic movement, sometimes the suction cup can be seen in the telescopic head.
Diagnosis
Diagnosis and diagnosis of vitreous cysticercosis
diagnosis
1. History of raw pork with food infected with cercaria.
2, early consciously black eyes fluttering, late vision loss.
3, the vitreous is turbid to varying degrees, the translucent light gray or light blue spherical capsule can be seen in the vitreous, and the center often has a grayish white or yellowish white round spot, which is the head of the cysticercus, sometimes visible in the vitreous Creeping.
4. Positive for intradermal test and complement fixation test.
Identification with vitreous degeneration and vitreous mild opacity, vitreous degeneration and vitreous opacity are characterized by vitreous liquefaction, posterior detachment, and atrophy leading to opacity. The normal vitreous is a transparent gel that denatures with age. The tendency is mainly condensed and liquefied, which is the result of depolymerization of mucopolysaccharide. The simple vitreous liquefaction has no obvious symptoms except for occasional "flying mosquitoes" in front of the eyes.
