On 24/7, representatives from the Vietnam-Sweden Uong Bi Hospital reported that the patient had experienced 20 days of eye redness and discomfort before seeking medical attention. Doctors diagnosed her with episcleritis in her right eye and discovered a thin, white, immobile strand beneath the conjunctiva in the inflamed area, suspecting a parasite.

Upon removing the foreign object, doctors were surprised to find a 4 cm long dead roundworm lodged under the conjunctiva of the eyeball at the site of the inflammation. The patient was then hospitalized for further examination to check for parasites in other organs. Fortunately, no other infections were found. She was treated with antibiotics, anti-inflammatory medication, and antiparasitic drugs. Her eye condition improved significantly, with no deep tissue damage observed.

Tests identified the worm as a Toxocara roundworm, a parasite commonly found in dogs and cats. It can be transmitted to humans through the consumption of contaminated food or water, contact with soil, or interaction with infected animals.

The patient's condition, while uncommon, is dangerous. Roundworm larvae can enter the body through the digestive system and travel through the bloodstream to various organs, including the liver, lungs, brain, and eyes, causing inflammation and potentially even blockages, which can be life-threatening. If the parasite enters the eyeball or conjunctiva, it can cause inflammation, reduced vision, and serious complications such as uveitis or retinal detachment.

To prevent infection, wash your hands thoroughly before eating and after contact with soil or pets. Regularly deworm children and pets. Avoid eating raw or undercooked vegetables and meat. If you experience persistent eye redness, pain, or a foreign body sensation, seek immediate medical attention from an eye specialist.
