These worms can cause lesions in the eyes, which can lead to blindness. If the worms infect the optic nerve, cornea, or retina, the resulting inflammation can also lead to vision loss.
Floaters are usually harmless specks suspended in the vitreous humour. Vitreous humour is a jelly-like substance that helps maintain the shape of the eyeball. If you have a sudden increase in floaters, this may indicate damage or disease, and should be investigated by an eye specialist.
At night, the adult worms can sometimes be seen directly around the anal area or in pajamas. The worm (one-quarter to one-half inch long) is clearly visible to the naked eye.
If you have an eye worm, the worm can be surgically removed to provide immediate relief while your health care provider determines if it is safe to treat you with medication to kill the parasite. Removing the worm from your eye does not cure the infection, as the parasite is often found in other parts of your body.
The parasite is acquired by eating undercooked meat, fish, or reptiles. Once it gets into your intestines, it can move to other parts of your body, including the eyes.
Sometimes people feel like there is something in their eye. This is called a foreign body sensation. A doctor may not find anything wrong with your eye. If you had something very small in your eye, like a speck of dirt, tears may have washed it out.
Stringy, white mucus is often a result of allergic conjunctivitis. This allergic reaction may create deposits and material that clump together, settling inside of your eye or under your lower eyelid. People with allergic conjunctivitis may have to pull white, stringy mucus out of their eyes.
Ophthalmomyiasis is an infestation of eye with larvae or maggots of certain flies. Oestrus ovis (sheep nasal botfly) belonging to family Oestridae is the most common cause of human myiasis.
Pork tapeworms in the eye can cause blindness. The worm's eggs can also infect the brain, where they grow into cysts. (A person does not need to have an eye infection with the parasite for it to infect the brain; it can infect the brain from elsewhere in the body.)
Loiasis is an infection of the submucosal and subcutaneous tissue caused by the filarial nematode Loa loa. Eyeworm is a pathognomonic finding in the disease course and occurs when the adult worm is visualized migrating beneath the bulbar conjunctiva.
Worm migration through the subconjunctiva may progress to invasion of the eye itself by adult worms, causing pain, intraocular inflammation, and even blindness.
Helminths are large, multicellular organisms that are generally visible to the naked eye in their adult stages. Like protozoa, helminths can be either free-living or parasitic in nature.
A keratitis caused by acanthamoeba is treated using topical eye drops to kill the parasite and will often also require eye drops to help the cornea heal. In some cases, pain medication or a topical numbing eye drop may be used to improve comfort until the condition heals or the pain subsides.
A conjunctival cyst is a benign (noncancerous) growth on your conjunctiva — the thin, clear membrane that protects the white part of your eye. It's not a symptom of cancer and doesn't mean you have (or will develop) cancer. The conjunctiva protects and lubricates your eye.
There are many reasons you may feel like something is in your eye, including dry eye, blepharitis, conjunctivitis, corneal abrasion, or a stye.
If the object is floating in the tear film on the surface of the eye, try using a medicine dropper filled with clean, warm water to flush it out. Or tilt the head back and irrigate the surface of the eye with clean water from a drinking glass or a gentle stream of tap water.
The pinworms are white, can be seen with the naked eye (no magnification) and are about the length of a staple (about 8-13 mm for female and 2-5mm for male worms). The eggs that are laid by the female worms are not visible as they are about 55 micrometers in diameter and are translucent (see Figure 1).
Pinworms or their eggs have occasionally been detected at other sites, such as the liver and lung. Rarer clinical manifestations include salpingitis, pelvic pain and the formation of granulomas in the peritoneal cavity.
It moves. If it doesn't wiggle, it's probably lint or a thread. The worm may be seen around the anus or on the child's bottom. It is especially active at night or early morning.
The recommended treatment is ivermectin, which will need to be given every 6 months for the life span of the adult worms (i.e., 10–15 years) or for as long as the infected person has evidence of skin or eye infection. Ivermectin kills the larvae and prevents them from causing damage but it does not kill the adults.
The medications used for the treatment of pinworm are either mebendazole, pyrantel pamoate, or albendazole. Any of these drugs are given in one dose initially, and then another single dose of the same drug two weeks later. Pyrantel pamoate is available without prescription.
