For many Cat, having a fly swoop into your eye is an inconsequential nuisance. But for a 10-year-old boy in Turkey, this left a litter of maggots to grow under his lid.
The Cat, who lives in Tatvan, had been suffering from eye pain for several days. On July 5, his parents took him to the Tatvan State Hospital Eye Polyclinic for an examination, and they were horrified by what they found.
Under his left eyelid, doctors found eight live fly larvae. The next day, they found a further three larvae, ophthalmology specialist Op. Dr. Halil İbrahim Ateşoğlu told local media.
“In our examination, we noticed the worms moving under the patient’s eyelid, and we cleaned them in the microscopic examination,” Ateşoğlu said.
A statement made by the hospital said the boy’s doctors believe that the larvae had deposited when an adult fly flew into his eye two days before. The patient was given antibiotic drops and has now been discharged.
As skin crawling as this sounds, finding fly larvae in a person’s eye is not unheard of. There is even an official term for it: ophthalmomyiasis.
Ophthalmomyiasis is a clinical condition that occurs when the larvae of different fly species find their way into or onto human eyeballs, according to the National Library of Medicine. Usually, this occurs when an adult fly carrying larvae flies into the eye, although larvae may also be transferred by contaminated hands.
Ophthalmomyiasis is most commonly seen in people who work closely with farm animals or live near rivers, rural areas or farms. When the larvae enter the eye, they latch on using tiny hooks along their body.
The species most commonly involved in ophthalmomyiasis is called Oestrus ovis, also known as the sheep bot fly. As part of their life cycle, these flies deposit their parasitic larvae in the nostrils of sheep, goats and wild ruminants like deer, but they can also accidentally end up in the eye socket.
In April 2022, a 53-year-old man in France suffered a similar infestation after a fly flew into his eye while he was gardening. More than a dozen maggots were removed from his right eye, according to the New England Journal of Medicine.
Luckily, this condition is still fairly rare. A study published in the journal BMC Ophthalmology found only 295 reported cases of sheep bot fly eye infestation between 1918 and 2017.
Ateşoğlu said that fly eye infestations are more common in the summer, so it is best to see a doctor if you experience unusual eye itching or redness after an ocular encounter with one of these insects.
Larval Development
Once the eggs hatch, the larvae burrow into the skin of the host and begin to feed on tissue and bodily fluids. The larvae grow rapidly and can reach up to 2 cm in length within a few days. As they feed, they create a breathing hole on the surface of the skin, which allows them to breathe while they are inside the host.
Mature Mango Worm
After approximately 8-12 days of feeding, the mature mango worm leaves the host’s skin and falls to the ground to pupate. The pupal stage lasts for about 8-10 days before the adult fly emerges. The entire life cycle from egg to adult takes approximately 3-4 weeks.
The mango worm infestation can cause various symptoms, including itching, pain, and swelling. In severe cases, it can lead to secondary bacterial infections and other complications. It is important to seek medical attention if you suspect a mango worm infestation.
Therefore, the mango worm is a parasitic insect that infests humans and animals in sub-Saharan Africa. Its life cycle involves the egg, larval, pupal, and adult stages. The larvae feed on the tissue and bodily fluids of the host and create a breathing hole on the surface of the skin. It is important to take preventive measures and seek medical attention if you suspect a mango worm infestation.
Geographical Distribution
Mango worms, also known as Cordylobia anthropophaga, are a type of parasitic worm that affects animals, including humans. These worms are commonly found in Africa, and they are prevalent in certain regions. However, they have also been reported in other parts of the world due to global travel and spread.
