Summary
First-ever Oestrus ovis ophthalmomyiasis case in Oman involved sixty larvae removed from a student's eye. Manual larval removal proved effective, highlighting the need for further myiasis surveys in the region.
Area of Science:
- Veterinary Ophthalmology
- Medical Entomology
- Parasitology
Background:
- Ophthalmomyiasis, an eye infection caused by fly larvae, is rare.
- The sheep nasal botfly (Oestrus ovis) is a known cause of myiasis in livestock and occasionally humans.
Observation:
- A case of external ophthalmomyiasis is reported for the first time in Oman.
- Sixty first-instar Oestrus ovis larvae were manually removed from the left eye of a 21-year-old male student.
- The patient acquired the infection during a field trip.
Findings:
- Manual removal using a swab stick was the sole effective treatment.
- Larval characteristics were documented with illustrations.
- The study discusses the prevalence of Oestrus ovis ophthalmomyiasis in the Middle East and notes local folk treatments.
Implications:
- While not a major public health concern in Oman currently, this case underscores the potential for Oestrus ovis infections.
- A nationwide survey of myiases is recommended to assess the broader scope of such parasitic infections.
- Understanding Oestrus ovis ophthalmomyiasis is crucial for veterinary and public health professionals in the region.
