8 strips were taken out from the old lady's eyes, about 3 cm long

      

　　The old lady of Qin's was hospitalized due to poor movement of the left limb left by cerebral hemorrhage, and she choked and coughed from drinking water. During the ward rounds, the patient reported eye discomfort. The careful doctor Jiang found that there was a thread-shaped white worm crawling in the patient's conjunctival sac, and immediately asked an ophthalmologist for consultation. The ophthalmologist examined under the microscope and saw that the conjunctiva was mildly congested, and there was a thread-shaped worm about 3 cm long and 0.5 mm thick on the temporal side of the left eye. He flipped the upper eyelid and continued to check, and found multiple live worms, and a total of 8 live worms were removed

　　Ophthalmologists based on experience and literature reports, determined that the body is conjunctival sucking nematodes. Conjunctival sucking nematodes are mainly parasitized in the conjunctival sac of dogs, cats and other animals, and can also parasitize in the human eye. The disease is mostly prevalent in Asia, so it is also called Oriental ophthalmopathy. Adult worms mainly parasitize in the conjunctival sac and tear duct of dogs, cats and other animals, and occasionally parasitize in the eyes of humans, rabbits and other animals. This worm is oviparous, and the female worm directly lays larvae in the conjunctival sac. When the intermediate host Drosophila licks the final host's eye secretions, it is sucked into the fly's body. After two molts, it develops into infected larvae and enters the fly's head and mou When the fly licks the eyes of humans or other animals, the infected larvae escape from the mouthparts of the fly and invade the host's eyes, and develop into adults after 15 to 20 days. The adult lifespan can reach more than 2 years. The number of parasites is 1 to several, and the maximum number can be more than 20.

　　This case reminds us to pay attention to eye hygiene and not play with dogs, cats and rabbits and other domestic animals. Friends who like to keep pets should pay attention to pet hygiene and disinfection, pay attention to environmental hygiene, and prevent the spread of pathogens.
