Eye disease caused by worms only

Worm eye diseases are not only common in Vietnam, but the Central Eye Hospital always receives patients who come in conjunctivitis, eyelid and granulomatous condition . After the test, the The doctor discovered, on the eyelid of the patient, there are pig tapeworm larvae, the parasite is located under the central retina.

Dr. Hoang Anh Tuan, Central Eye Hospital, said that 50-year-old NTC patients in Coc Phong, Chi Tan, Khoai Chau and Hung Yen were hospitalized when their right eye got stuck, the outer corner of the eyelid corner had one red block, size fast. Clinical examination and doing some diagnostic tests have nothing special, only histopathological examination, eye biopsy shows that the outermost is a fibrous capsule, followed by inflamed granules with new vessels and many types of inflammatory cells such as neutrophils, lymphocytes, giant cells of foreign bodies, the innermost are transverse or slightly cross-sectioned worms with thick occium, inner muscle layers containing worm larvae only onchocerca.

50-year-old TTS patient in group 18D, Tuong Mai ward, Hai Ba Trung district, Hanoi 10 days before going to hospital, had right upper eyelid swelling, all treated with small antibiotics (cylaxan) did not support. In the Central Eye Hospital for examination and detection test, in the upper right eyelid of patient S, there is a 0.5cm size tumor, firm density, mobility, painless pressing, mild congestive conjunctiva . The patient had surgery to remove the tumor. After using the cocher pliers to remove the tumor, the sheath ruptured a yellow mucus that flowed out and followed it with a living worm head (wiggling). Doctors have to take pince to pull out 2 4cm worms, thick occium, inside contains many thelazia larvae. These are two typical cases of eye disease caused by worms detected and treated by Central Eye Hospital.

In some parts of West Africa, South America, Guatemala, Mexico, parasitic eye disease is a relatively common disease, especially by worms. In Vietnam, no research has mentioned this disease. However, in fact, many people suffer; but not detected. According to ophthalmologists, eye diseases caused by worms often leave serious consequences such as decreased vision, even blindness. The parasitic pathogens of the eye are single-celled acanthamoeba, toxoplasma, parasitic worms . Parasitic worms in the eye cause swelling of the eyelids, conjunctivitis, keratitis, uveitis, retinal inflammation, opaque glass vesicles and atrophy of the nerve.

The treatment for cases of eye disease caused by worms is mainly surgical. Surgery is both a diagnosis and an effect of removing the parasite, the use of new drugs is effective because it can kill the remaining worms if surgery is not done. Common drugs are diethylcarbamazin at a dose of 3-6mg / kg / 24 hours. Use for 5 consecutive days.

The eye disease caused by worms is only a rare disease, so it is difficult to determine exactly which type of worm is causing it. In order to diagnose the type of pathogenic worms, it is imperative that professionals rely on factors such as epidemiological regions, clinical symptoms, histopathological tests, parasitic tests, antigenic and resistance reactions. , PCR techniques . From there, there will be effective treatments.
