Recently, Professor Chen Weiqi and Dr.
Huang Zijing of Shantou International Eye Center published a case report in the New England Journal of Medicine (NEJM)
.
A 34-year-old man came to the hospital for examination because of foreign body sensation and itching in his right eye.
He has no known medical history and lives on a farm with his dog
.
Slit-lamp microscopic examination showed that there were two worms under the upper eyelid of his right eye.
After local anesthesia was given, the worms were removed using fine forceps
.
These worms were identified as Thelazia callipaeda (Thelazia callipaeda)
.
One month after the treatment, the patient’s eye itching disappeared, there was no foreign body sensation in the eye, and no recurrence occurred
.
Diagnosed as ocular trematodiasis
.
T.
callipaeda is a parasite carried and spread by fruit flies that feed on ocular secretions and deposit the larvae in the eyes of the ultimate host (usually dogs, but occasionally humans)
.
Conjunctival sucking nematode (Thelazia callipaeda) is a kind of nematode of the sucking nematode genus
.
It is mainly parasitic in the conjunctival sac and tear ducts of dogs, cats and other animals.
It can also be parasitic in human eyes, causing conjunctival sucking nematode disease (thelaziasis)
.
When the intermediate host fruit fly sucks the ocular secretions of the final host, it is sucked into the body of the fly.
After two molting, it develops into an infected larva and enters the fly's head and mouthparts
.
When the flies are sucked into the eyes of other animals, the infected larvae escape from the fly's mouthparts and invade the eyes of the host, and develop into adults after 15 to 20 days
.
Adults can live for more than 2 years
.
The disease is mostly prevalent in Asia, so it is also called oriental eye worm disease
