What Eye Diseases Are Caused By Parasites?

The parasite is usually harmful to the eyes
The eyes are the windows of the soul, but the eyes can also contain dangerous diseases caused by scary parasites. These terrifying creatures parasitize and cause disease in the eye, leading to keratitis infection, blurred vision and even permanent blindness.
1. Baylisascaris procyonis nematode
These worms often live parasites on pandas. However, it can parasitize humans, in addition to them living on the body of more than 100 species of birds and some other mammals

. They can cause blindness, nerve damage or death in humans. Humans usually only detect the disease after the eggs hatch into larvae. The larvae travel through the intestinal wall and move into different tissues and organs, and when the larvae enter the brain or the eyes, they will seriously damage the brain and eyes The worm is dangerous in that its eggs are well adapted to a variety of environmental conditions If exposed to moist environments, the eggs of this worm can survive for about 5 years. Diagnosis of the disease is made by identifying the larvae in biopsy of specimens or by serological examination.

2. The round nematode Thelazia
Dogs, buffaloes, cows and horses are common hosts for Thelazia spp, but humans and other mammals are also likely to be infected, early-stage larvae introduced into intermediate intestines such as flies. Drosophilid in Amioto, and Muscid in Musca and Fannia, when they eat tears and other religious practices. In the gastrointestinal tract of the intermediate host will develop through different stages, until the third stage comes out of the follicle and moves to the mouth of the fly, when the flies eat the tears of the host. The larvae enter the host's conjunctival sac and become adult worms after about 1 month The parasitic worms in the eyes cause inflammation and tear, which can cause infections Severe infections often cause fear of light, edema, conjunctivitis, and possible blindness.
3. Acanthamoeba
Acanthamoeba spp, commonly found in contact lenses, swimming pools, lakes, tap water, radiators and air conditioners. Several species of parasites in the group Acanthamoeba, including A.



.culbertsoni, A.polyphaga, A.castellanii, A.astronyxis, Ahatchetti, A.rhysodes, A.divionensis, A.lenticulata and A.lugdunensis are related to the patient. They live by eating bacteria, bacteria commonly found in dirty contact lenses.



. Once they enter the eye, Acanthamoeba causes keratitis, an eye infection that usually occurs in healthy people. The consequence of this is that Acanthamoeba will cause itchy eyes, pain, redness, blurred vision, and severe cases can lead to permanent vision loss or blindness Because of similar characteristics to the symptoms of other eye infections, early diagnosis is critical and necessary for the effective treatment of Acanthamoeba keratitis.
4. Toxocariasis
Toxocariasis is a parasitic disease caused by the larvae of two types of Toxocara nematodes: Toxocara canis from dogs and Toxocara cati from cats. Ocular toxocariasis occurs when Toxocara worm larvae migrate to the eye. Symptoms and signs of ophthalmic toxocariasis, such as reduced vision, eye inflammation or retinal damage, usually only one eye is affected Toxocariasis is considered one of the parasitic diseases that are gradually forgotten, Toxocariasis is in the group of 5 parasitic diseases that has been set by the CDC of the United States as a target for public health action.
5. Taenia solium
Humans can become infected with T. solium by swallowing eggs found in food, water or from poor hygiene.



Larvae, depending on the parasite site of the cysts, have different manifestations of the disease: pimples are located under the pea skin, are easy to move, painless, non-itchy, located in striated muscle. , or may have epilepsy, paralysis of the legs, arms or hemiplegia, severe headache, memory disorders, or glaucoma, vision loss, or blindness if there is a cyst tapeworm in the eye. The disease caused by T. solium not only affects the health and life of patients but it also reduces the value of pigs, cattle and is unsafe for people to eat. T. solium is still a forgotten disease, and was added to the list of forgotten tropical diseases by WHO in 2010.
6. Toxoplasmosis
Toxoplasmosis is considered one of the leading causes of food-related deaths in the United States More than 60 million people in the United States, men and women in the United States carry the toxoplasmosis parasite, but most have very few symptoms because the immune system often inhibits the ability of the parasite to cause disease. However, women who have just been infected with Toxoplasmosis during pregnancy when the immune system is impaired so Toxoplasmosis can have serious consequences.



. If we and a family member have recently been infected with Toxoplasma before or during pregnancy, then you can pass the infection on to the baby. Infected newborns have almost no symptoms at birth but may later p.
