Summary
A case of Thelazia callipaeda eyeworm infection was documented in a 23-year-old Korean woman. This study details the clinical presentation and morphological characteristics of the parasite, Thelazia callipaeda.
Area of Science:
- Ophthalmology
- Parasitology
- Veterinary Ophthalmology
Background:
- Thelazia callipaeda, a zoonotic eyeworm, can cause ocular discomfort and visual impairment in humans.
- Human infections with Thelazia callipaeda are relatively rare, with limited documented cases globally.
Purpose of the Study:
- To report a case of Thelazia callipaeda infection in a Korean female.
- To describe the clinical findings and morphological features of the identified eyeworm.
Main Methods:
- Clinical observation of a patient presenting with ocular symptoms.
- Morphological examination of the retrieved Thelazia callipaeda worm under microscopy.
- Detailed measurement of the worm's dimensions and anatomical structures.
Main Results:
- A 23-year-old Korean female presented with foreign body sensation and lacrimation in her right eye.
- A slender, creamy white Thelazia callipaeda worm, measuring 10.5mm in length, was recovered from the affected eye.
- Microscopic analysis revealed characteristic features including a chitinoid oral capsule, a moderately short esophagus, a blunt tail, and dissimilar spicules.
Conclusions:
- This case highlights the potential for Thelazia callipaeda to infect humans, causing ocular discomfort.
- Accurate identification and morphological description of the parasite are crucial for diagnosis and understanding its biology.
- Further surveillance and awareness are necessary to manage and prevent Thelazia callipaeda infections in both human and animal populations.
